Architectural design
The document discusses architectural design, which involves identifying system subsystems and frameworks for communication. Key architectural decisions address important requirements and are documented. Architecture decisions are important to communicate rationale for changes and trace decisions to requirements. Architectural views represent different perspectives of a system through modules, processes, distribution, and development structure using the 4+1 model.

Management decision making involves choosing between rational alternatives using management science tools. These tools include linear programming to optimally allocate limited resources, expected value and decision trees to aid decisions under risk, and maximax, maximin, and Hurwicz criteria to guide decisions with uncertainty. Management science formulates problems, builds mathematical models, tests models, derives solutions, and applies solutions to real systems.
Decision supporting system
A decision support system (DSS) is a computer-based information system that supports business or organizational decision-making activities. It can handle large amounts of data from different sources, provide flexible reporting and presentations, and perform complex analysis and comparisons using advanced software. DSSs serve management, operations, and planning levels of an organization by supporting activities like sensitivity analysis, "what-if" analysis, and goal-seeking analysis to evaluate alternative decisions and help choose the best option. The example described is a DSS used at RUKMANI BAJAJ in Indore to help the CEO and management make informed decisions.
Introduction to system development and systems analysis
This document introduces system development and systems analysis. It discusses the system development life cycle which includes planning, analysis, design, implementation, and maintenance. It also covers feasibility analysis, behavioral aspects of change management, and system analysis techniques. The key aspects covered are the system development cycle, planning techniques like PERT and Gantt charts, factors that influence behavioral resistance to change, and steps for system analysis including initial investigation, system survey, and feasibility study.
Power point for project
Software architecture is the process of defining a structured solution that meets technical and operational requirements while optimizing attributes like performance, security, and manageability. It involves decisions that can significantly impact quality, performance, maintainability, and success. Like any complex structure, software must be built on a solid foundation, and failing to consider key scenarios or future needs can put the application at risk. The goals of architecture are to understand requirements, identify how to implement use cases technically, and create a system that hides implementation details while meeting stakeholder needs.
Presentation of Management of Information System
in this presentation all peoples see what is system and why developed the system and in this presentation also defined steps of SDLC (system development life cycle )
TREA - transparent enterprise architecture
The document discusses the challenges of managing complex and interconnected IT environments. It proposes using an architectural model and management platform to address these challenges. The solution involves three steps: 1) Creating a unified model of the entire IT environment across four levels. 2) Leveraging the model to optimize systems and ensure compliance. 3) Using the model to support future implementations, modernizations and growth. The model provides visibility, insights and a baseline for strategic alignment of IT assets with business needs.
System Analysis and Design
System analysis and design involves developing a complete information system including hardware, software, people, procedures, and data. System analysis is the process of understanding the current system by collecting data, analyzing processes, and identifying problems and improvements. System design develops the new system based on requirements and analysis, proceeding from general design to detailed design. Tools like flowcharts, data flow diagrams, and structured English are used to describe the system design.

An Introduction to Systems Engineering | Dorleco
Systems engineering is a methodical approach to planning, designing, and managing complex systems throughout their lifecycles. It takes a holistic view of systems, considering technical and non-technical factors. The key principles include taking a holistic approach, requirements analysis, an iterative design process, and interdisciplinary collaboration. Systems engineering follows a structured lifecycle including concept development, design, testing, and maintenance. It provides benefits such as optimized design, risk management, and flexibility, though it can also be time-consuming and resource-intensive. Overall, systems engineering offers a valuable way to tackle complexity in engineering projects.

Concept of systemThe word “system” has a very wide connotation. B.pdf
Concept of system:
The word “system” has a very wide connotation. Broadly speaking, we have a wide variety of
systems around us. Several of them have been created by man to satisfy his needs while others
exist in nature. Natural systems are those that came into existence through natural processes
whereas man-made systems are those in which human beings intervene through components,
attributes, or relationships. Examples of man-made systems are highways, railways, waterways,
marine and air transport, space projects, chemical plants, nuclear plants, electrical power
generation, distribution and utilization, housing and office complexes, mining and oil extraction,
etc
Systems engineering:
Systems engineering is an interdisciplinary field of engineering and engineering management
that focuses on how to design and manage complex systems over their life cycles. At its core
systems engineering utilizes systems thinking principles to organize this body of knowledge.
Issues such as requirements engineering, reliability, logistics, coordination of different teams,
testing and evaluation, maintainability and many other disciplines necessary for successful
system development, design, implementation, and ultimate decommission become more difficult
when dealing with large or complex projects. Systems engineering deals with work-processes,
optimization methods, and risk management tools in such projects. It overlaps technical and
human-centred disciplines such as industrial engineering, mechanical engineering,
manufacturing engineering, control engineering, software engineering, electrical engineering,
cybernetics, organizational studies, engineering management and project management. Systems
engineering ensures that all likely aspects of a project or system are considered, and integrated
into a whole.
The systems engineering process is a discovery process that is quite unlike a manufacturing
process. A manufacturing process is focused on repetitive activities that achieve high quality
outputs with minimum cost and time. The systems engineering process must begin by
discovering the real problems that need to be resolved, and identify the most probable or highest
impact failures that can occur – systems engineering involves finding elegant solutions to these
problems. That’s why Systems engineering is sometimes called process engineering.
Systems engineering over-all systems design:
The need for systems engineering arose with the increase in complexity of systems and projects
in turn exponentially increasing the possibility of component friction, and therefore the
unreliability of the design. When speaking in this context, complexity incorporates not only
engineering systems, but also the logical human organization of data. At the same time, a system
can become more complex due to an increase in size as well as with an increase in the amount of
data, variables, or the number of fields that are involved in the design. The International Space
Station is an exa.

Selecting A Development Approach For Competitive Advantage
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.

The document discusses architectural design and provides information on architectural design decisions, views, patterns, and levels of abstraction. It describes architecture in the small as concerned with individual programs, while architecture in the large refers to complex enterprise systems. There are advantages to explicitly designing architecture such as stakeholder communication, system analysis, and large-scale reuse. Architectural views include logical, process, development, and physical views. Design decisions depend on requirements like performance, security, safety, availability, and maintainability. Common patterns include model-view-controller and layered architectures.
Efficient organizational improvements
Tim Ayres proposes a vision for efficient organizational improvements through the effective use of an Integrated Life Cycle Management Framework (ILCM). The ILCM framework includes six tenants: life cycle planning and integration, expectation management, collaborative requirements management, life cycle systems engineering, technology planning and insertion, and continual integrated testing. Ayres argues that adopting these ILCM principles will help organizations achieve greater synergy, overcome dysfunctional silos, and improve their ability to develop and sustain effective systems on budget.

It discusses how areas like modularity, documentation, programming languages, design patterns, and model-driven engineering relate to sustainable design. It highlights challenges like precisely defining sustainability and finding ways to evaluate the costs and benefits of sustainable design practices. The goal is to develop sustainable design as a quality attribute and incentivize its use.
Service oriented configuration management of software architecture
Software configuration management (SCM) is an important activity in the software engineering life cycle. SCM by control of the evolution process of products leads to constancy and stability in software systems. Nowadays, use of software configuration management is essential during the process of software development as rules to control and manage the evolution of software systems. SCM effects different levels of abstraction included the architectural level. Configuration of software architecture causes improvement in the configuration of the lower abstraction levels. CM of software architecture is more significant in large scale software with longevity of life cycle. Traditional SCM approaches, at the architectural level, do not provided the necessary support to software configuration management, so systems that use these approaches are faced with problems. These problems arise because of the lack of a serious constant and repeated changes in the software process. To overcome this it is necessary to create an infrastructure. Hence, a service oriented approach for configuration management is presented in this paper. In this approach, the activities of configuration management are conducted from a service oriented viewpoint. This approach was also used to try and control the evolution and number of versions of different software systems in order to identify, organize and control change and reforms during the production process. This approach can compose services and create composite services for new undefined activities of configuration.

A reliability estimation framework for OO design complexity perspective has been developed inthis paper. The proposed framework correlates the object oriented design constructs with complexity and also correlates complexity with reliability. No such framework has been available in the literature that estimates software reliability of OO design by taking complexity into consideration. The framework bridges the gap between object oriented design constructs, complexity and reliability. Framework measures and minimizes the complexity of software design at the early stage of software development life cycle leading to a reliable end product. Reliability and complexity estimation models have been proposed by following the proposed framework. Complexity estimation model has been developed which takes OO design constructs into consideration and proposed reliability estimation models take complexity in consideration for estimating reliability of OO design.
Software Architecture and Design Introduction
The document discusses software architecture and design. It defines software architecture as describing a system's major components, their relationships, and how they interact. Software design provides a plan for how system elements fit and work together. An important role of architecture is to identify requirements that affect structure and reduce risks. Quality attributes, both static and dynamic, are important non-functional properties like maintainability, performance, and security. Architects must consider these attributes and deliver solutions that technical teams can implement.
EVALUATION OF THE SOFTWARE ARCHITECTURE STYLES FROM MAINTAINABILITY VIEWPOINT
In the process of software architecture design, different decisions are made that have systemwide
impact. An important decision of design stage is the selection of a suitable software
architecture style. Lack of investigation on the quantitative impact of architecture styles on
software quality attributes is the main problem in using such styles. So, the use of architecture
styles in designing is based on the intuition of software developers. The aim of this research is
to quantify the impacts of architecture styles on software maintainability. In this study,
architecture styles are evaluated based on coupling, complexity and cohesion metrics and
ranked by analytic hierarchy process from maintainability viewpoint. The main contribution of
this paper is quantification and ranking of software architecture styles from the perspective of
maintainability quality attribute at stage of architectural style selection.

Sustainability On Large Rev 1 01 31 11
Large, complex engineering and construction programs may be found in all industry sectors ranging from extractive industries such as oil, gas and mining through infrastructure programs for transportation, water and power. Common to all of these programs is the potential they have to positively or negatively influence financial, social and environmental performance of both the implementing organization as well as the communities and stakeholders they touch.
Together, financial, social and environmental outcomes define the three elements of sustainability or a program’s “triple bottom line”
The attached paper looks at some of the challenges and opportunities programs present as well as a framework for application of sustainability principles in a program management approach.

Estimating techniques for an acquisition program progresses from analogies to actual cost method as the program matures and more information is known. The analogy method is most appropriate early in the program life cycle when the system is not yet fully defined.
Lecture-_-5-_SDA_software design and architecture.doc
This lecture discusses software architecture. It begins by explaining that software architecture refers to the structure of a system, including its software elements, their properties, and relationships. An example diagram is shown but it is noted that the diagram alone does not represent the full architecture. Common architectural structures like patterns, reference models, and reference architectures are introduced. The lecture emphasizes that architecture is important because it enables communication between stakeholders, represents early critical design decisions, and can provide reusable abstractions of systems.

- 1. Solution design considerations are normally considered in either one or two dimensions, namely the infrastructure layer or application tier. These two dimensions are also normally considered exclusive to each other. At Mediaring, Cavu Corp and its subsidiaries, our solution design key considerations are done in a holistic manner, utilizing three dimensions. The third and critical dimension consists of systemic qualities that encompass the infrastructure layer and application tiers. While systemic qualities may be considered in projects and solutions, these are typically an afterthought and this is where projects and solutions go awry. These three dimensions are not considered exclusive to each other. Rather, these dimensions have to be considered as inter-related. The benefits of utilizing these three dimensions holistically are enormous as it reduces unnecessary technology risks and delays to critical projects, resulting in stable, manageable and secure solutions.
