Managing usability evaluation practices in agile development environmentsIJECEIAES
Usability evaluation is a core usability activity that minimizes risks and improves product quality. The returns from usability evaluation are undeniable. Neglecting such evaluation at the development stage negatively affects software usability. In this paper, the authors develop a software management tool used to incorporate usability evaluation activities into the agile environment. Using this tool, agile development teams can manage a continuous evaluation process, tightly coupled with the development process, allowing them to develop high quality software products with adequate level of usability. The tool was evaluated through verification, followed by the validation on satisfaction. The evaluation results show that the tool increased software development practitioner satisfaction and is practical for supporting usability work in software projects.
Selecting A Development Approach For Competitive Advantagemtoddne
Companies that rely on their information systems to provide a competitive advantage must employ development methodologies that: facilitate innovation, improve customer and supplier relationships, and enable change at the speed of business. Potential development approaches include traditional, object-oriented, and vision and value oriented methodologies. The recommended approach is a hybrid methodology that incorporates agility, adaptability, reuse, collaborative thinking, and evolving innovation. At the foundation of this approach are agile development philosophies and practices, and the system designer. From an architectural perspective, the approach utilizes SOAs and SOMA methods. And, design thinking and innovation evolution cycle principles are incorporated to drive system innovations.

Consequently measuring and evaluating the quality of a software product has become a critical task for many companies.
Several models have been proposed to help diverse types of users with quality issues. The development of techniques for

AN APPROACH TO IMPROVEMENT THE USABILITY IN SOFTWARE PRODUCTSijseajournal
One of the significantaspects of software quality is usability. It is one of the characteristics that judge by
the success or failure of software applications. The most important risk facing the software applications is
usability which may lead to the existence of a gap between users and systems. This may lead to system
failure because of Poor design. This is due to the design is not based on the desires and requirements of the
customer. To overcome these problems, this paper proposed an approach to improve usability of software
applications to meet the needs of the customer and interacts with the user easily with an efficient and
effective manner.The proposed approach is based prototyping technique due to itssimplicity and it does not
require additional costs to elicit precise and complete requirement and design.

A METHOD FOR WEBSITE USABILITY EVALUATION: A COMPARATIVE ANALYSISIJwest
ABSTRACT
Graphical user interfaces design in software development process focuses on maximizing usability and the user's experience, in order to make the interaction for users easy, flexible and efficient. In this paper, we propose an approach for evaluating the usability satisfaction degree of a web-based system. The proposed method has been accomplished in two phases and implemented on an airlines website as a case study. In the first phase, a website usability test is implemented by a number of users, and then the results obtained are translated into charts for a final web-based system evaluation in the second phase. The results achieved
were satisfactory, since the places where the weaknesses and gaps in the website are identified and recommended solutions to avoid them are drawn. The authenticity of the results have been confirmed by comparing them with user opinions acquired from a questionnaire, which proves the precision in which the website is rated.

Integral part of software development cycle is SQA, evaluation of software Quality product when compared to other industrial projects and it is very highly difficult. For developing, performance, speed, maintaining the quality, cost and efficiency of the software, SQA activities, principles and its methods are implemented in the early stages of the software engineering development phases. Where in this paper there is little visibility of lack of software Quality product in the view of poor practices. Hence we proposed a new system with best practices in software quality management to make the best quality product. This System works on Gain Better Visibility into Supplier Quality with Technology.
A FRAMEWORK FOR INTEGRATING USABILITY PRACTICES INTO SMALL-SIZED SOFTWARE DEV...ijseajournal
Usability now appears to be a highly important attribute for software quality; it is a critical factor that
needs to be considered by every software-development organization when developing software to improve
customer satisfaction and increase competition in the market. There exists a lack of a reference model or
framework for small-sized software-development organizations to indicate which usability practices should
be implemented, and where in the system-development life cycle they need to be considered. We offer
developers who have the objective of integrating usability practices into their development life cycle a
framework that characterizes 10 selected user-centered design (UCD) methods in relation to five relevant
criteria based on some ISO factors that have an effect on the selection of methods (ISO/TR16982). The
selection of the methods for inclusion in the framework responds to these organizations’ needs; and we
selected basic methods that are recommended, cost-effective, simple to plan and apply, and easy to learn by
developers; and which can be applied when time, resources, skills, and expertise are limited. We favor
methods that are generally applicable across a wide range of development environments. The selected
methods are organized in the framework according to the stages in the development process where they
might be applied. The only requirement for the existing development life cycle is that it to be based on an
iterative approach.
The performance of an algorithm can be improved using a parallel computing programming approach. In this study, the performance of bubble sort algorithm on various computer specifications has been applied. Experimental results have shown that parallel computing programming can save significant time performance by 61%-65% compared to serial computing programming.

Software development process presents various types of models with their corresponding phases required to be accordingly followed in delivery of quality products and projects. Despite the various expertise and skills of systems analysts, designers, and programmers, systems failure is inevitable when a suitable development process model is not followed. This paper focuses on the Iterative and Incremental Development (IID)model and justified its role in the analysis and design software systems. The paper adopted the qualitative research approach that justified and harnessed the relevance of IID in the context of systems analysis and design using the Vocational
Career Information System (VCIS) as a case study. The paper viewed the IID as a change-driven software development process model. The results showed some system specification, functional specification of system and design specifications that can be used in implementing the VCIS using the IID model. Thus, the paper concluded that in systems analysis and design, it is imperative to consider a suitable development process that reflects the engineering mind-set, with heavy emphasis on good analysis and design for quality assurance.

Smart Sim Selector: A Software for Simulation Software SelectionCSCJournals
In a period of continuous change in global business environment, organizations, large and small, are finding it increasingly difficult to deal with, and adjust to the demands for such change. Simulation is a powerful tool for allowing designers imagine new systems and enabling them to both quantify and observe behavior. Currently the market offers a variety of simulation software packages. Some are less expensive than others. Some are generic and can be used in a wide variety of application areas while others are more specific. Some have powerful features for modeling while others provide only basic features. Modeling approaches and strategies are different for different packages. Companies are seeking advice about the desirable features of software for manufacturing simulation, depending on the purpose of its use. Because of this, the importance of an adequate approach to simulation software selection is apparent. Smart Sim Selector is a software developed for the purpose of providing support for users when selecting simulation software. Smart Sim Selector consists of a database which is linked to an interface developed using Visual Basic 6.0. The system queries a database and finds a simulation package suitable to the user, based on requirements which have been specified. This paper provides an insight into the development of Smart Sim Selector, in addition to the reasoning behind the system.
A Guideline Tool for Ongoing Product Evaluation in Small and Medium-Sized Ent...IJECEIAES
As consumer demand for user friendly software increases, usability evaluation is crucial to develop software systems which are easy to learn and use. However, implementation of usability evaluation is challenging for small and medium-sized enterprises (SMEs) due to factors such as lack of technical expertise, knowledge and experience of methods and standards. This results in neglect, or poorly executed evaluations of projects, resulting in software that disappoints and frustrates clients. To overcome this loss of competitiveness, we propose here a visual incorporation tool derived from ISO standards that would assist software development teams in SMEs in understanding and implementing usability evaluations. It shows fundamental Usability Engineering (UE) and Software Engineering (SE) activities and artifacts relevant to the usability evaluation and software development process, with potential incorporation points being highlighted. Dependencies and relationships are shown by links between activities and artifacts. Additionally, convergent artifacts of both disciplines were identified and shown. Evaluation of the proposed tool was based on the questionnaire results of software development practitioners from SMEs.

Rework is a known vicious circle in software development since it plays a central role in the generation of
delays, extra costs and diverse risks introduced after software delivery. It eventually triggers a negative
impact on the quality of the software developed. In order to cater the rework issue, this paper goes in depth
with the notion of rework in software development as it occurs in practice by analysing a development
process on an organisation in Mauritius where rework is a major issue. Meticulous strategies to reduce
rework are then analysed and discussed. The paper ultimately leads to the recommendation of the best
strategy that is software configuration management to reduce the rework problem in software development
An Elite Model for COTS Component Selection ProcessIJEACS
Component-based software development (CBD) promises development of high-quality trustworthy software systems within specified budget and deadline. The selection of the most appropriate component based on specific requirement plays a vital role for high-quality software product. Multi-Agent software (MAS) engineering approach played a crucial role for selection of the most appropriate component based on a specific requirement in a distributed environment. In this paper, multi agent technique is used for component selection. A semi-automated solution to COTS component selection is proposed. It is evident from the result that (MAS) plays an essential role and is suitable for component selection in a distributed environment keeping in view of the system design and testing strategies.

The objective of usability activities at the implementation stage are to ensure that detailed design takes account of usability principles.
This can be achieved by:
use of style guides and design guidelines
ensuring that rapid prototyping activities incorporate usability
With interconnectivity between IT Service Providers and their customers and partners growing, fueled by
proliferation of IT Services Outsourcing, with some providers gaining leading positions in marketplace
today, challenges are faced by teams who are tasked to deliver integration projects with much desired
efficiencies both in cost and schedule. Such integrations are growing both in volume and complexity.
Integrations between different autonomous systems such as workflow systems of the providers and their
customers are an important element of this emerging paradigm. In this paper we present an efficient model
to implement such interfaces between autonomous workflow systems with close attention given to major
phases of these projects, from requirement gathering/analysis, to configuration/coding, to
validation/verification, several levels of testing and finally deployment. By deploying a comprehensive
strategy and implementing it in a real corporate environment, a 10%-20% reduction in cost and schedule
year over year was achieved for past several years primarily by improving testing techniques and detecting
bugs earlier in the development life-cycle. Some practical considerations are outlined in addition to
detailing the strategy for testing the autonomous system integrations domain.

As consumer demand for user friendly software increases, usability evaluation is crucial to develop software systems which are easy to learn and use. However, implementation of usability evaluation is challenging for small and medium-sized enterprises (SMEs) due to factors such as lack of technical expertise, knowledge and experience of methods and standards. This results in neglect, or poorly executed evaluations of projects, resulting in software that disappoints and frustrates clients. To overcome this loss of competitiveness, we propose here a visual incorporation tool derived from ISO standards that would assist software development teams in SMEs in understanding and implementing usability evaluations. It shows fundamental Usability Engineering (UE) and Software Engineering (SE) activities and artifacts relevant to the usability evaluation and software development process, with potential incorporation points being highlighted. Dependencies and relationships are shown by links between activities and artifacts. Additionally, convergent artifacts of both disciplines were identified and shown. Evaluation of the proposed tool was based on the questionnaire results of software development practitioners from SMEs.

With interconnectivity between IT Service Providers and their customers and partners growing, fueled by
proliferation of IT Services Outsourcing, with some providers gaining leading positions in marketplace
today, challenges are faced by teams who are tasked to deliver integration projects with much desired
efficiencies both in cost and schedule. Such integrations are growing both in volume and complexity.
Integrations between different autonomous systems such as workflow systems of the providers and their
customers are an important element of this emerging paradigm. In this paper we present an efficient model
to implement such interfaces between autonomous workflow systems with close attention given to major
phases of these projects, from requirement gathering/analysis, to configuration/coding, to
validation/verification, several levels of testing and finally deployment. By deploying a comprehensive
strategy and implementing it in a real corporate environment, a 10%-20% reduction in cost and schedule
year over year was achieved for past several years primarily by improving testing techniques and detecting
bugs earlier in the development life-cycle. Some practical considerations are outlined in addition to
detailing the strategy for testing the autonomous system integrations domain.

The impact of user involvement in software development processnooriasukmaningtyas
In software development process, user can take part in any phase of the process, depending on what model is being applied. Lack of user involvement can result in a poorly designed solution, or even a solution that conflicts with user’s needs. This review paper presents the impact of user involvement in software development process. In this study, different software development processes will be reviewed, show where the user usually gets involved in different models such as: structural (waterfall, Vmodel) and incremental (scrum-extreme programming XP). As each model differs from the other, each of them has a different perspective of where user should take part and where they should not. This can be an asset that helps project managers, and leaders to develop suitable strategies to follow in their projects.
THE IMPACT OF IN-HOUSE SOFTWARE DEVELOPMENT PRACTICES ON SYSTEM USABILITY IN ...IJMIT JOURNAL
In-house software development is a critical phenomenon for the production of efficient and effective
software in generating requisite job output. A few studies have devoted efforts towards establishing the
impact of in-house software development on software. Therefore, this paper is an effort towards
establishing the impact of in-house software development practices on system usability. In pursuit of this
paper, a sample of a sample size of 169, at 95% confidence level, with margin error of 5% was drawn from
bold software users, i.e. 300 employees who used the all software including those dealing with the main
stream activities. A total of 102 respondents actually responded to the questionnaires. The Online Sample
Calculator was used to draw the sample. Quantitative data were collected using semi-structured
questionnaires and processed using the SPSS. Descriptive statistics were applied in the analysis. Findings
of the study indicate that software development practices, specifically usability test and user involvement in
software designing and development had an impact on determining software usability for in-house
software. The paper concludes that software development practices shape the design of the software; hence
influence usability of the software produced. Recommended is therefore that software usability test and
user involvement in software designing and development be promoted for effective software production.
Best Practices for Improving User Interface Designijseajournal
A rich and effective computational system must have a friendly user interface with appealing usability features that provides excellent user experience. In order to develop interactive systems with the best user experience, an innovative iterative approach to user interface engineering is required because it is one of the most challenging areas given the diversity of knowledge, ideas, skills and creativity needed for building smart interfaces in order to succeed in today’s rapidly paced and tough, competitive marketplace. Many modeling aspects including analytical, intuitive, artistic, technical, graphical, mathematical, psychological and programming models need to be considered in the development process of an effective user interface. This research examines some of the past practices and recommends a set of guidelines for designing effective user interfaces. It also demonstrates how UML use case diagrams can be enhanced by relating user interface elements to use cases.

DESQA a Software Quality Assurance FrameworkIJERA Editor
In current software development lifecycles of heterogeneous environments, the pitfalls businesses have to face are that software defect tracking, measurements and quality assurance do not start early enough in the development process. In fact the cost of fixing a defect in a production environment is much higher than in the initial phases of the Software Development Life Cycle (SDLC) which is particularly true for Service Oriented Architecture (SOA). Thus the aim of this study is to develop a new framework for defect tracking and detection and quality estimation for early stages particularly for the design stage of the SDLC. Part of the objectives of this work is to conceptualize, borrow and customize from known frameworks, such as object-oriented programming to build a solid framework using automated rule based intelligent mechanisms to detect and classify defects in software design of SOA. The implementation part demonstrated how the framework can predict the quality level of the designed software. The results showed a good level of quality estimation can be achieved based on the number of design attributes, the number of quality attributes and the number of SOA Design Defects. Assessment shows that metrics provide guidelines to indicate the progress that a software system has made and the quality of design. Using these guidelines, we can develop more usable and maintainable software systems to fulfill the demand of efficient systems for software applications. Another valuable result coming from this study is that developers are trying to keep backwards compatibility when they introduce new functionality. Sometimes, in the same newly-introduced elements developers perform necessary breaking changes in future versions. In that way they give time to their clients to adapt their systems. This is a very valuable practice for the developers because they have more time to assess the quality of their software before releasing it. Other improvements in this research include investigation of other design attributes and SOA Design Defects which can be computed in extending the tests we performed.
USEFul: A Framework to Mainstream Web Site Usability through Automated Evalua...Waqas Tariq
A paradox has been observed whereby web site usability is proven to be an essential element in a web site, yet at the same time there exist an abundance of web pages with poor usability. This discrepancy is the result of limitations that are currently preventing web developers in the commercial sector from producing usable web sites. In this paper we propose a framework whose objective is to alleviate this problem by automating certain aspects of the usability evaluation process. Mainstreaming comes as a result of automation, therefore enabling a non-expert in the field of usability to conduct the evaluation. This results in reducing the costs associated with such evaluation. Additionally, the framework allows the flexibility of adding, modifying or deleting guidelines without altering the code that references them since the guidelines and the code are two separate components. A comparison of the evaluation results carried out using the framework against published evaluations of web sites carried out by web site usability professionals reveals that the framework is able to automatically identify the majority of usability violations. Due to the consistency with which it evaluates, it identified additional guideline-related violations that were not identified by the human evaluators.
Agile techniques that utilize iterative development are broadly used in various industry projects as a lightweight development technique which can satisfy the continuous changes of requirements. Short repetitions are used that are required for efficient product delivery. Traditional and old software development methods are not much efficient and effective to control the rapid change in requirements. Despite the benefits of Agile, criticism on agile methodology states that it couldn’t succeed to pay attention to architectural and design issues and therefore is bound to produce small design-decisions. The past decade has observed numerous changes in systems development with many organizations accepting agile techniques as a viable methodology for developing systems. An increase in the number of research studies reveals the growing demand and acceptance of agile methodologies. While most research has focused on acceptance rate and adaptation of agile practices, there is very limited knowledge of their post-adoption usage and incorporation within organizations. Several factors explain the effective usage of agile methodologies. A combination of previous research in Agile Methodologies, Diffusion of Innovations, Information Systems implementation, and Systems Development has been carried out to develop a research model that identifies the main factors relevant to the propagation and effective usage of agile methodologies in organizations.
AN IMPROVED REPOSITORY STRUCTURE TO IDENTIFY, SELECT AND INTEGRATE COMPONENTS...ijseajournal
An ultimate goal of software development is to build high quality products. The customers of software
industry always demand for high-quality products quickly and cost effectively. The component-based
development (CBD) is the most suitable methodology for the software companies to meet the demands of
target market. To opt CBD, the software development teams have to customize generic components that are
available in the market and it is very difficult for the development teams to choose the suitable components
from the millions of third party and commercial off the shelf (COTS) components. On the other hand, the
development of in-house repository is tedious and time consuming. In this paper, we propose an easy and
understandable repository structure to provide helpful information about stored components like how to
identify, select, retrieve and integrate components. The proposed repository will also provide previous
assessments of developers and end-users about the selected component. The proposed repository will help
the software companies by reducing the customization effort, improving the quality of developed software
and preventing integrating unfamiliar components.

Structural and Morphological Studies of Nano Composite Polymer Gel Electroly...vivatechijri
n today’s society, we stand before a change in energy scarcity. As our civilization grows, many
countries in thedeveloping world seek to have the standard of living that has been exclusive to a few nations, so
their arises a need in thedevelopment of technology that is compatible enough with the resources provided by
nature in order to have sustainabledevelopment to all class of the society. In order to overcomethe prevailing
challenges of huge energy crises in near future, there is an urgent need for the development of electrical
vehiclesor hybrid electrical vehicles with low CO2 emissions using renewable energy sources. In view of the
above, electrochemicalcapacitors can fulfil the requirements to some extent.Preparation of nano composite
polymer gel electrolyte is the best optional product to overcome these problems. When fillers are added or
dispersed to the polymer gel electrolyte, amorphous or porous nature of electrolyte increases which enhances
the liquid absorbing quality of polymer and helps in removing the drawbacks of polymer gel electrolytes such as
leakage, poor mechanical and thermal stability etc. In this work dispersion of SiO2 nano filler is done in the

An Alternative to Hard Drives in the Coming Future:DNA-BASED DATA STORAGEvivatechijri
Demand for data storage is growing exponentially, but the capacity of existing storage media is not keeping up, there emerges a requirement for a storage medium with high capacity, high storage density, and possibility to face up to extreme environmental conditions. According to a research in 2018, every minute Google conducted 3.88 million searches, other people posted 49,000 photos on Instagram, sent 159,362,760 e-mails, tweeted 473,000 times and watched 4.33 million videos on YouTube. In 2020 it estimated a creation of 1.7 megabytes of knowledge per second per person globally, which translates to about 418 zettabytes during a single year. The magnetic or optical data-storage systems that currently hold this volume of 0s and 1s typically cannot last for quite a century. Running data centres takes vast amounts of energy. In short, we are close to have a substantial data-storage problem which will only become more severe over time. Deoxyribonucleic acid (DNA) are often potentially used for these purposes because it isn't much different from the traditional method utilized in a computer. DNA’s information density is notable, 215 petabytes or 215 million gigabytes of data can be stored in just one gram of DNA. First we can encode all data at a molecular level and then store it in a medium that will last for a while and not become out-dated just like floppy disks. Due to the improved techniques for reading and writing DNA, a rapid increase is observed in the amount of possible data storage in DNA.
The usage of chatbots has increased tremendously since past few years. A conversational interface is an interface that the user can interact with by means of a conversation. The conversation can occur by speech but also by text input. When a chatty interface uses text, it is also described as a chatbot or a conversational medium. During this study, the user experience factors of these so called chatbots were investigated. The prime objective is “to spot the state of the art in chatbot usability and applied human-computer interaction methodologies, to research the way to assess chatbots usability". Two sorts of chatbots are formulated, one with and one without personalisation factors. the planning of this research may be a two-by-two factorial design. The independent variables are the two chatbots (unpersonalised versus personalised) and thus the speci?c task or goal the user are ready to do with the chatbot within the ?nancial ?eld (a simple versus a posh task). The results are that there was no noteworthy interaction effect between personalisation and task on the user experience of chatbots. A signi?cant di?erence was found between the two tasks with regard to the user experience of chatbots, however this variation wasn't because of personalisation.

Cross Platform Development Using Fluttervivatechijri
Today the development of cross-platform mobile application has under the state of compromise. The developers are not willing to choose an alternative of either building the similar app many times for many operating systems or to accept a lowest common denominator and optimal solution that will going to trade the native speed, accuracy for portability. The Flutter is an open-source SDK for creating high-performance, high fidelity mobile apps for the development of iOS and Android. Few significant features of flutter are - Just-in-time compilation (JIT), Ahead- of-time compilation (AOT compilation) into a native (system-dependent) machine code so that the resulting binary file can execute natively. The Flutter’s hot reload functionality helps us to understand quickly and easily experiment, build UIs, add features, and fix bugs. Hot reload works by injecting updated source code files into the running Dart Virtual Machine (VM). With the help of Flutter, we believe that we would be having a solution that gives us the best of both worlds: hardware accelerated graphics and UI, powered by native ARM code, targeting both popular mobile operating systems.

Recommender System (RS) has emerged as a significant research interest that aims to assist users to seek out items online by providing suggestions that closely match their interests. Recommender system, an information filtering technology employed in many items is presented in internet sites as per the interest of users, and is implemented in applications like movies, music, venue, books, research articles, tourism and social media normally. Recommender systems research is usually supported comparisons of predictive accuracy: the higher the evaluation scores, the higher the recommender. One amongst the leading approaches was the utilization of advice systems to proactively recommend scholarly papers to individual researchers. In today's world, time has more value and therefore the researchers haven't any much time to spend on trying to find the proper articles in line with their research domain. Recommender Systems are designed to suggest users the things that best fit the user needs and preferences. Recommender systems typically produce an inventory of recommendations in one among two ways -through collaborative or content-based filtering. Additionally, both the general public and also the non-public used descriptive metadata are used. The scope of the advice is therefore limited to variety of documents which are either publicly available or which are granted copyright permits. Recommendation systems (RS) support users and developers of varied computer and software systems to beat information overload, perform information discovery tasks and approximate computation, among others.

The advancement of Information Technology has hastened the ability to disseminate information across the globe. In particular, the recent trends in ‘Social Networking’ have led to a spark in personally sensitive information being published on the World Wide Web. While such socially active websites are creative tools for expressing one’s personality it also entails serious privacy concerns. Thus, Social Networking websites could be termed a double edged sword. It is important for the law to keep abreast of these developments in technology. The purpose of this paper is to demonstrate the limits of extending existing laws to battle privacy intrusions in the Internet especially in the context of social networking. It is suggested that privacy specific legislation is the most appropriate means of protecting online privacy. In doing so it is important to maintain a balance between the competing right of expression, the failure of which may hinder the reaping of benefits offered by Internet technology
Google File System was innovatively created by Google engineers and it is ready for production in record time. The success of Google is to attributed the efficient search algorithm, and also to the underlying commodity hardware. As Google run number of application then Google’s goal became to build a vast storage network out of inexpensive commodity hardware.

The entire file system is organized hierarchically in directories and identified by pathnames. The architecture comprises of multiple chunk servers, multiple clients and a single master. Files are divided into chunks, and that is the key design parameter. Google File System also uses leases and mutation order in their design to achieve atomicity and consistency. As of there fault tolerance, Google file system is highly available, replicas of chunk servers and master exists.
A Study of Tokenization of Real Estate Using Blockchain Technologyvivatechijri
Real estate is by far one of the most trusted investments that people have preferred, being a lucrative investment it provides a steady source of income in the form of lease and rents. Although there are numerous advantages, one of the key downsides of real estate investments is lack of liquidity. Thus, even though global real estate investments amount to about twice the size of investments in stock markets, the number of investors in the real estate market is significantly lower. Block chain technology has real potential in addressing the issues of liquidity and transparency, opening the market to even retail investors. Owing to the functionality and flexibility of creating Security Tokens, which are backed by real-world assets, real estate can be made liquid with the help of Special Purpose Vehicles. Tokens of ERC 777 standard, which represent fractional ownership of the real estate can be purchased by an investor and these tokens can also be listed on secondary exchanges. The robustness of Smart Contracts can enable the efficient transfer of tokens and seamless distribution of earnings amongst the investors. This work describes Ethereum blockchainbased solutions to make the existing Real Estate investment system much more efficient.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Abstract : The Usability Metric for User Experience (UMUX) is a four-item Likert scale used for the
subjective assessment of an application’s perceived usability. It is designed to provide results similar to those
obtained with the 10-item System Usability Scale, and is organized around the ISO 9241-11 definition of
usability. A pilot version was assembled from candidate items, which was then tested alongside the System
Usability Scale during usability testing. It was shown that the two scales correlate well, are reliable, and both
align on one underlying usability factor. In addition, the Usability Metric for User Experience is compact
enough to serve as a usability module in a broader user experience metric
Keywords - metric,system usability scale,usability,user experience.
I. INTRODUCTION
Usability can be measured, but it is rarely Metrics are expensive and are a poor use of typically scarce
usability resources. Although measuring usability can cost fourfold the maximum amount as conducting
qualitative studies (which often generate better insight), metrics are sometimes well worth the expense. Among
other things, metrics can help managers track design progress and support decisions about when to release a
product. As organizations increase their usability investments, collecting actual measurements is a natural next
step and does provide benefits. In general, usability metrics let you: Track progress between releases. You
cannot fine-tune your methodology unless you recognize how well you're doing. Assess your competitive
position. Are you better or worse than other companies? Where are you better or worse? Make a Stop/Go
decision before launch. Is the design ok to release to an unsuspecting world? Create bonus plans for design
managers and higher-level executives. For example, you'll determine bonus amounts for development project
leaders supported what percentage customer-support calls or emails their products generated during the year.
Usability may be a quality attribute that assesses how easy user interfaces are to use. The word "usability" also
refers to methods for improving ease-of-use during the planning process.
Usability is defined by 5 quality components:
Learnability: How easy is it for users to accomplish basic tasks the primary time they encounter the design?
Efficiency: Once users have learned the planning , how quickly can they perform tasks? Memorability: When
users return to the planning after a period of not using it, how easily can they re-establish proficiency? Errors:
what percentage errors do users make, how severe are these errors, and the way easily can they get over the
errors? Satisfaction: How pleasant is it to use the planning There are many other important quality attributes. A
key one is utility, which refers to the design's functionality: Does it do what users need?
Usability and utility are equally important and together determine whether something is useful: It matters little
that something is straightforward if it isn't what you would like

RELATED WORK
Software development organizations contains marketing, design, project management, development and
quality assurance team. it's important for the various teams within the organization to know the
advantages and limitation of incorporating various usability testing methods within the software development
life cycle. Some reasons for poor usability include effort prioritization conflicts from development, project
management, and style team. The part played by the usability engineer is to urge involved because
the heuristic judge and facilitate the event and style efforts are supported usability principles and at an
equivalent time adhering to the project period of time . Two approaches for usability inspection methods
consist of user experience testing and expert review or more commonly referred to as Heuristic Evaluation
(HE). This paper focuses on understanding the strength of HE as a strategy for defect detection. The results also
increase the need for integrating traditional heuristics with modified heuristics customized to the domain or field
of the project being tested such as E-Government.[1]
. Describes an innovative methodology developed for usability tests of the IEEE PCS internet site that
combines heuristic evaluation and task-based testing. Tests conducted on the PCS Web site has evaluated
whether the location facilitated members' ability to seek out information and participate in
discussions, also as developers' are capable to seek out , contribute, and manage administrative
information on the location . The distinctive social characteristics of Communities of Practice (CoPs)
provide context for tailoring design heuristics for informational internet sites that serve the
requirements and interests of CoP members. The discussion gives important on technical communication
principles that apply not only to evaluating the effectiveness of the PCS internet site design but also to all
or any centralised. f the PCS Web site design but also to all centralised technical communication products and
media that increasingly demand user participation.[2] Here Proposes a usability testing method that alters a
given usability testing method to form it less expensive and time consuming for the investigator. The
usage of user-centred methods is stimulated and a mixture of two centralised methods suggested. Future
this method is combined with other techniques to additionally detect the state of satisfaction within the
participant.
User based features like emotions, opinions, cognitive and conative effects are therefore are
considered. a way for the joint analysis of all data gathered is proposed.[3] More automated system
testing might be instrumental in achieving these goals and in recent years testing tools are developed to
automate the interaction with software systems at the GUI level. However, there's absence knowledge on
the usability and applicability of these tools in an industrial setting. This study analyses two tools for
automated visual GUI testing on a real-world, safety-critical software is developed by the corporate Saab
AB.
The tools are compared supported their characteristics also as how they support automation of system
test cases that have previously been presented manually. The time to develop and the size of the
automated test cases also as their execution times are evaluated.[4] Usability testing is important to be
performed by software development companies to determine whether their products are usable or
unusable. it's equally important for the end- users companies running usability studies also . This paper
represents the event of
Usability Management System (USEMATE), an automatic system as an alternate solution
to assist usability tester or practitioner to run usability testing more efficiently and effectively.
The main objective of USEMATE is to enhance the present systems which are paper-based,
require manual score calculation using excel and manual reaction time recording into a webbased
management system. The tools used for the event compromise Adobe Photoshop CS2, Adobe
Dreamweaver CS3, Apache Web Server, and a private computer (PC). The modules and
usefulness criteria included and therefore the approach utilized in the event of this automated system
were replicated from a case study on usability testing of a webpage conducted earlier. USEMATE is
envisaged to be ready to minimize the lengthy working hour and energy needed to manage the usability
testing process from phase to phase.[5]
Usage of traditional UT techniques which aren't sufficient and suitable with the growing
complexity of internet sites & constraints faced by usability practitioners. For a sample, the Lab
Based Usability Testing (LBUT) is dear and has lesser coverage than Exploratory
Heuristics Evaluation (EHE) while the EHE is subjected to false alarms. A hybrid usability
methodology (HUM) comprising of LBUT and EHE is obtainable . Six experiments involving
EHE and LBUT were performed at the first , in-between and future stages of the SDLC of
websites, during which the simplest relative performance of every method were measured using
the dependent variables followed by the planning of a HUM. To prove the HUM, four case

practitioners and also provides stakeholders a validated situational deciding
framework for usability testing strategies taking under consideration world constraints.[6]
II. METHODOLOGY
usability may be a multidimensional concept that aims into the fulfillment of certain set of goals,
mainly; effectiveness, efficiency and satisfaction” and without these goals, usability can't be achieved.
Effectiveness: this term refers to the accuracy and completeness of the user goal achievement.
Efficiency: refers to the resources exhausted by users so as to make sure an accurate and completed achievement
of the goals.
Satisfaction refers to the subjective thoughts of the user regarding their attitude, level of comfort, relevance
of application and therefore the acceptability of use.
A system or a product is completely hooked in to its specific and distinct context of use, the character of the
task, the users appointed to require the task, and finally the equipment used to perform it.
Measuring the usability of a certain system can be done through the measurement of the three goals using a
number of observable and quantifiable usability metrics.
In the light of the three goals mentioned earlier, we’ll go through the different metrics used to measure each
goal, however, our main focus will be on the Effectiveness It can be measured through using two usability
metrics: Success rate, called also completion rate and the number of errors .Success rate/ completion rate: is the
percentage of users who were able to successfully complete the tasks. Despite the very fact that this metric
remains unable to supply insights on how the tasks were performed or why users fail just in case of failure,
they're still critical and are at the core of usability.The success rate is one of the most commonly used metric for
most of practitioners, where 79% of them reported using the success rate as the first metric to think about for
simple use and through data collection and interpretation.
The success rate metric are often measured by assigning a binary value of 0 and 1 to the users; where 1 is
assigned to those that successfully complete the task and 0 to the ones who fail to do so.”Once the test is over
and you have all the data you need to calculate your success rate, the next step would be to divide the total
number of correctly completed attempts by the total number of attempts multiplied by 100.The completion rate
is easy to measure and to collect but with one major pitfall to consider; it happens frequently when a user stops
at some point during the task and fails to end it or maybe finishes it but not in the expected way.Taking into
account that they have completed some steps successfully in the task, how would you score what they have
accomplished as an evaluator?I am getting to dive a touch bit into the small print on the way to score you users
taking under consideration the various stages of their success or failure, using an example to illustrate.
Let’s consider, for instance, that your user task is to order a box of dark chocolates with a card to their
mother for mother’s day.The scoring might seem simple at first glance, and you'll easily say; if the mother
receives the box of bittersweet chocolate with the cardboard then it's a case of success. On the opposite hand, if
the mother doesn't receive anything then we will simply say, that this is often a case of failure.
However, it’s not that straightforward , there are other considerations:
Ordered a box of chocolate but not the dark one (white or milky or a spread of these) alongside card.
Ordered the proper chocolate box without a present card
Ordered quite one box of chocolate by mistake and a present card
Ordered a box of chocolate but didn’t add delivery information or address
Ordered a box of chocolates and gift card successfully but to the incorrect address
All these cases entail a percentage of success and failure within the process of fulfilling the task, their failure
is partial also as their success, which simply means that as an evaluator you would like to interact your own
personal opinion within the scoring.
If you decided that there are no middle grounds in the estimated scoring, your success rate would be different
from that obtained when you appreciate the effort they have made in spite of the task you planned for them.
The fact that there is not a steady rule when it comes to scoring your users, and oftentimes success rates
become subjective; because different evaluators won’t have the same scoring and estimate an equivalent
percentage of failure or success for the above cases, within the same way. However, so as to mainstream the
method , you'd like to work out the important aspects of the task and what score you would allot each a part of
it.

Success rate remains the only usability metric and therefore the easiest among the entire range of those
usability signals, mainly because it’s quick and straightforward and doesn't require much preparation and time to
gather and most significantly it enables you from tracking the progress within your system being one among the
overall areas commonly employed by marketers and designers right along , to ascertain the large picture of how
well their system is doing at the extent of user experience, this doesn't change the very fact , that it remains
subjective.
Help the designers and developers to ascertain that uncovering problems isn't a symbol of
failure. nobody does an ideal job the initially time only. Users always surprise us. It's much better to seek
out out about the issues with a some users during a usability test than later when the design is being
reviewed and is out there within the marketplace. [7]
2. The Number of Errors
This metric provides an idea about the average number of times where an error occurred per user when
performing a given task.These errors can be either slips; where the user accidently types the incorrect email
address or picks the incorrect dates when making a reservation or booking a flight, or they will be mistakes
where the user clicks on an image that’s not clickable or even double clicks a button or a link
intentionally.Normally any users of any interactive system may make errors, where 2 out of every 3 users err,
and there's absolutely no such thing as a ‘’perfect’’ system anyway..To help you measure and ensure obtaining
great diagnostic results, it is highly recommended to set a short description where you give details about how to
score those errors and the severity of a certain of an error to show you how simple and intuitive your system is.
3. Time-Based Efficiency
Or referred to as time on task, this metric helps in the measurement of the time spent by the user to complete
the task or speed of work. This consequently means there's an immediate relationship between the efficiency
and effectiveness, and that we can say, that efficiency is really the user effectiveness divided by the user time
spent.
4. The Overall Relative Efficiency
This is actually measured through users who successfully completed the task in relation to the total time
taken by all users.Let’s consider that we have 2 users where each one of is supposed to complete a different
task.The first user has successfully completed task (1) yet failed to complete task (2). While the second hand has
did not complete task (1) but completed task (2) successfully.
5.Post Task Satisfaction
Once your users have finished the task and it doesn’t matter whether complete it successfully or not, it’s time
to hand them over a questionnaire to have an idea about the difficulty of the task from the users point of
view.Generally, these tasks consist of 5 questions, and the idea behind them give your users a space to judge the
usability of your system.
6. Task Level Satisfaction
This metric helps into investigating the overall impression of users confronted with the system. To measure
the level of satisfaction you can either use the smiley scale method where the user is expected to choose one of
the 5 smileys as a reflection of their satisfaction or lack of satisfaction.The Word Method is also use to measure
the user’s level of satisfaction through listing a series of positive and negative connotations highlighted in green
and red respectively.
In light of the conceptual framework we have discussed earlier, the user experience is highly influenced by
everything that surrounds it.However, the tide might be turning on usability funding. I've recently worked on
several projects to determine formal usability metrics in several companies. As organizations increase their
usability investments, collecting actual measurements is a natural next step and does provide benefits. In
general, usability metrics let you:
Track progress between releases. You cannot fine-tune your methodology unless you recognize how well you're
doing.Assess your competitive position. Are you better or worse than other companies? Where are you better or
worse?Make a Stop/Go decision before launch. Is the design ok to release to an unsuspecting world?
Create bonus plans for design managers and higher-level executives. For example, you'll determine bonus
amounts for development project leaders supported what percentage customer-support calls or emails their
products generated during the year.

It is easy to specify usability metrics, but hard to gather them. Typically, usability is measured relative to
users' performance on a given set of test tasks. The most basic measures are supported the definition of usability
as a top quality metric:
success rate (whether users can perform the task at all),
the time a task requires,
the error rate, and
users' subjective satisfaction.[8]
It is also possible to collect more specific metrics, such as the percentage of time that users follow an
optimal navigation path or the number of times they need to back track. You can collect usability metrics for
both novice users and experienced users. Few websites have truly expert users, since people rarely spend
enough time on any given site to find out it in great detail. Given this, most websites benefit most from studying
novice users. Exceptions are sites like Yahoo and Amazon, which have highly committed and constant users and
may enjoy studying expert users. Intranets, extranets, and weblications are almost like traditional software
design and can hopefully have skilled users; studying experienced users is thus more important than working
with the novice users who typically dominate public websites. With qualitative user testing, it is enough to test
3–5 users. After the fifth user tests, you've got all the insight you're likely to urge and your best bet is to travel
back to the drafting board and improve the design so that you can test it again. Testing quite five users wastes
resources, reducing the amount of design iterations and compromising the ultimate design quality.
Unfortunately, when you're collecting usability metrics, you want to test with quite five users. In order to urge a
fairly tight confidence interval on the results, I usually recommend testing 20 users for every design. Thus,
conducting quantitative usability studies is approximately fourfold as expensive as conducting qualitative ones.
Considering that you simply can learn more from the simpler studies, I usually recommend against metrics
unless the project is extremely well funded.success rate or the completion rate because it’s gives a general idea
about the performance of the system.

To illustrate quantitative results, we can look at those recently posted by Macromedia from its usability study of
a Flash site, aimed at showing that Flash is not necessarily bad. Basically, Macromedia took a design,
redesigned it according to a set of usability guidelines, and tested both versions with a group of users. Here are
the results:

V. CONCLUSION
usability metrics, it's possible to watch and quantify the usability of any system irrespective if it's software,
hardware, web-based or a mobile application. This is because the metrics presented here are supported extensive
research and testing by various academics and experts and have withstood the test of your time .
Moreover, they cover all of the three core elements that constitute the definition of usability: effectiveness,
efficiency and satisfaction, thus ensuring an all-round quantification of the usability of the system being tested.
usability gets side-tracked and becomes something which will be addressed afterward . Tracking the usability of
your product with metrics allows you to possess a transparent understanding of the experience you're providing
to your users, and improve it over time. usability metrics are measured and aggregated into actionable results,
which allows you to act instantly on the info you record. That makes it painless to stay track of how your
design's usability progresses, detect issues, and improve your users' experience
