Software Engineering Methodologies
The document describes the evolution of software development methodologies over time, from the 1950s to the 2000s. It discusses several models including code and fix, waterfall model, spiral model, V-model, and agile methods. The waterfall model was introduced in the 1970s and emphasized sequential development through requirements, design, implementation, testing, integration, and maintenance phases. The spiral model was developed in the 1980s to address limitations of the waterfall model through an iterative, risk-driven approach. The V-model emerged in the 1990s and depicted the relationships between project phases and testing activities.
SDLC Waterfall Model
The Waterfall model of the Software Development Life Cycle (SDLC) involves sequential phases of initiation, requirements, design, construction, testing, and implementation. Key project documents like the Business Requirements Document, Functional Requirements Document, and High Level Design are created, reviewed, and signed off on by stakeholders as the project progresses through each phase. Testing involves both system integration testing by the technology team and user acceptance testing by end users to identify and fix defects before final implementation.
Agile model
The agile model is an iterative and incremental software development process that focuses on quick delivery of working software in short cycles. Requirements are broken into small parts that can be developed incrementally to minimize risk and reduce delivery time. Each iteration is typically 1-4 weeks where a cross-functional team plans, designs, codes, tests, and demos a working product to stakeholders before starting the next iteration. Multiple iterations may be needed to fully develop the product or new features.
Introduction to software development methodologies- Agile vs Waterfall
This document discusses different software development methodologies, including Waterfall, Agile, Scrum, and Kanban. It defines a project and software development methodology. Waterfall follows sequential phases of requirements, design, development, testing, and delivery, while Agile focuses on iterative delivery, customer collaboration, and response to change. The document examines differences between Waterfall and Agile approaches to scope, schedule, team roles, testing practices, and other factors. It provides guidance on choosing a methodology based on requirements stability, team experience, project scale, and other criteria.
Waterfall Model
The document discusses the waterfall model of software development. It describes the waterfall model as a linear sequential approach where progress flows from one phase to the next like a waterfall. The key phases are requirement analysis, design, development, testing, deployment, and maintenance. Each phase has distinct requirements and activities. The waterfall model works well for smaller, well-defined projects but has disadvantages for complex projects where requirements may change.
sdlc
This document provides an overview of the Software Development Life Cycle (SDLC) and different SDLC models, including Waterfall, Incremental, Agile, and Spiral models. It describes the key phases and characteristics of each model, and discusses their advantages and disadvantages. The Waterfall model is a simple linear sequential approach, while Incremental is divided into modules with each release adding functionality. Agile uses rapid iterative cycles for continuous delivery, and Spiral emphasizes risk analysis with repeated planning, risk analysis, engineering and evaluation phases. Understanding SDLC helps improve quality, productivity and reduces risks of going over budget or delivering late.
SDLC- concept and models
The document discusses the System Development Life Cycle (SDLC), which is a standard model used worldwide to develop software. It describes the main stages of the SDLC as analysis, planning, implementation, and testing. Analysis is the first and most important phase where requirements are determined and the problem is broken down. Planning involves assigning tasks to team members. Implementation is the longest and most expensive phase. Testing is an ongoing phase where thorough testing takes place. The document also discusses various SDLC models including waterfall, iterative enhancement, prototyping, spiral, build and fix, and rapid application development models.
Sohrab Waterfall Vs Rad
This document summarizes two software development models: the waterfall model and the RAD (Rapid Application Development) model. The waterfall model is described as a sequential process that begins with analysis and progresses through subsequent phases of design, implementation, testing, and maintenance. Some advantages are provided but also limitations around inflexibility. The RAD model is then introduced as a variation that emphasizes short development cycles through concurrent processing and component-based construction.

The Waterfall Model
The document describes the Waterfall Model of software development. It consists of sequential phases: requirements, design, implementation, testing, and deployment. While easy to understand, it has disadvantages like inability to change requirements later in the process and lack of early working software. The document also discusses improving the model by adding design phases, documentation, testing planning, and customer involvement.
Waterfall model
The document discusses the waterfall model, which is a sequential software development process where progress flows steadily from one phase to the next - conception, initiation, analysis, design, construction, testing, production/implementation, and maintenance. The key phases and deliverables are completed one at a time before moving to the next phase. The waterfall model is simple and easy to understand, manage, and works well for smaller projects with well-defined requirements. However, it is inflexible and carries high risks since changes are difficult once a later phase has begun and no working software is produced until late in the lifecycle. The model is not suitable for complex, long-term, or ambiguous projects where requirements may change.

Rapid prototyping technologies,applications &part deposition planning 2
Rapid prototyping technologies allow for the quick fabrication of scale models using 3D CAD data. The document discusses several rapid prototyping processes like stereolithography, fused deposition modeling, and selective laser sintering. It also covers part deposition planning, which determines part accuracy, surface quality, build time and cost based on factors like tessellation, slicing, and orientation. While rapid prototyping enables faster design iterations, limitations include poor surface finish and limited strength compared to final production parts.
1 rapid prototyping model
Rapid prototyping is a process that involves quickly building a prototype or working model to test design features, ideas, concepts, functionality, output, and performance before fully developing the final product. It originated in the late 1960s and became more accessible in the 1980s. Rapid prototyping decreases development time by allowing for early corrections and has advantages like increasing variants, complexity, communication and decreasing delivery times and costly mistakes. However, it can fail to replicate the real product and overlook problems, requiring endless revisions. The rapid prototyping process involves analyzing requirements, identifying objects and actions, organizing them logically, getting feedback, and iterating the prototype-feedback cycle until customers are satisfied before final development.
Rapid application development model
The Rapid Application Development (RAD) model is an incremental model that delivers software to users early by devoting less time to planning and more time to development. It uses a combination of Joint Application Development techniques and CASE tools to convert user needs into designs through collaboration between system developers and users. Feedback from development is then used to refine requirements and design. The RAD model aims to complete projects on time and within budget while identifying problems early through its fast iterative development process.
Chapter 2 software development life cycle models
The document discusses several software development life cycle models including:
- Build and Fix model - A simple two phase model of building code without design then fixing issues. Not suitable for projects over 200 lines of code.
- Waterfall model - A sequential model consisting of requirements, design, implementation, testing, and maintenance phases. Difficult to define all requirements up front.
- Incremental and iterative models - Deliver working versions in cycles with additional functionality added each cycle.
- Spiral model - Addresses project risks through risk analysis phases. Each phase involves planning, risk analysis, development and customer evaluation in a spiral pattern.
RAD Model & Prototyping Of Software Engineering
The document discusses the RAD model and prototyping. The RAD model is an incremental software development process where components are developed in parallel. It has four phases: requirements planning, user design, construction, and cutover. Prototyping involves creating initial versions of the system to get user feedback and evolve the design before full development. There are two types of prototypes: throwaway prototypes that are not part of the final system, and evolutionary prototypes that are iteratively improved based on user feedback.
Rad model
Rapid Application Development (RAD) is an agile software development methodology that focuses on rapid prototyping through workshops and iterative testing with customers. It involves business modeling to identify information flows, data modeling to define necessary data objects, and process modeling to convert data objects into business processes. Automated tools are then used to generate code from the models. The RAD model aims to reduce development time through reusability, early customer feedback, and short iteration cycles enabled by powerful modeling and code generation tools. However, it relies on strong individual performances, is only suitable for modularized systems, and requires high modeling and development skills.
Software design methodologies
The document discusses various software development methodologies and life cycle models that have been used since the 1950s. It provides detailed descriptions of the waterfall model, spiral model, evolutionary prototyping, and staged delivery approaches. Each methodology takes different approaches to requirements analysis, design, development, testing, and deployment. The document emphasizes the importance of choosing a life cycle model that fits the needs of the specific project.
System Development Life Cycle (SDLC)
The document discusses the system development life cycle (SDLC) as a systematic method for organizations to implement change through new technologies. It describes the four phases of SDLC - planning, analysis, design, and implementation. The planning phase involves feasibility studies to understand economic, organizational, and technical factors. The analysis phase breaks down the problem and gathers stakeholder requirements. The design phase decides if the system will be internal or outsourced. The implementation phase builds, tests, trains users on, and evaluates the new system. SDLC provides a systematic strategy for large development projects involving many stakeholders.
Process models
Process models describe the life cycle of software development from requirements gathering to maintenance. The main process models discussed are waterfall, incremental, RAD, prototype, spiral and concurrent development. Each model represents the phases and flow of activities in the software development process in a different way. Process models help develop software in a systematic manner and ensure all team members understand responsibilities and timelines.

2-models.pptx
The document discusses several software process models, including:
- The waterfall model, which progresses through requirements, design, implementation, testing, and maintenance in a linear fashion. It is easy to understand but inflexible.
- The prototyping model, which builds prototypes to help refine requirements rather than freezing them early. This gets feedback from customers but prototypes may be mistaken for finished products.
- The spiral model, which is iterative and incremental, with each pass through the loop addressing process risks and allowing revisions of previous decisions.

2. Specialized process models for component-based development and formal methods are described. The unified process framework is also introduced as a iterative and incremental object-oriented development approach.
3. Key aspects of various process models like waterfall, spiral development and unified process are summarized, including their phases and characteristics.
Soft engg introduction and process models
The document discusses several software process models:
- The Linear Sequential (Waterfall) Model is a simple, systematic approach where each phase must be completed before moving to the next. It is best for small, well-defined projects.
- The Incremental Model applies the Linear Sequential Model iteratively to increments, delivering working software in stages. This allows for early delivery and flexibility.
- The Prototyping Model involves building prototypes to refine requirements through client feedback in iterations. This helps establish clear objectives.
- Rapid Application Development (RAD) is a fast version of the Linear Sequential Model using a component-based approach to accelerate delivery of fully functional projects.

Modelos de desarrollo de software
The document discusses several software development process models:
- The waterfall model is one of the first proposed models and follows a linear sequence of phases but does not allow for iteration.
- The V-model is a variation of the waterfall model that uses testing at each phase to verify the previous phase.
- Prototyping allows repeated investigation of requirements or design to reduce risk.
- The transformational model applies a series of transformations to formally specify a system.
- Phased development delivers a system in increments or iterates on subsystems with each release.
- The spiral model combines development activities with risk management through iterative cycles.

From Concept to reality : Implementing Lean Managements DMAIC Methodology for...
The Ready-Made Garments (RMG) industry in Bangladesh is a cornerstone of the economy, but increasing costs and stagnant productivity pose significant challenges to profitability. This study explores the implementation of Lean Management in the Sampling Section of RMG factories to enhance productivity. Drawing from a comprehensive literature review, theoretical framework, and action research methodology, the study identifies key areas for improvement and proposes solutions.
Through the DMAIC approach (Define, Measure, Analyze, Improve, Control), the research identifies low productivity as the primary problem in the Sampling Section, with a PPH (Productivity per head) of only 4.0. Using Lean Management techniques such as 5S, Standardized work, PDCA/Kaizen, KANBAN, and Quick Changeover, the study addresses issues such as pre and post Quick Changeover (QCO) time, improper line balancing, and sudden plan changes.
The research employs regression analysis to test hypotheses, revealing a significant correlation between reducing QCO time and increasing productivity. With a regression equation of Y = -0.000501X + 6.72 and an R-squared value of 0.98, the study demonstrates a strong relationship between the independent variables (QCO downtime and improper line balancing downtime) and the dependent variable (productivity per head).
The findings suggest that by implementing Lean Management practices and addressing key productivity inhibitors, RMG factories can achieve substantial improvements in efficiency and profitability. The study provides valuable insights for practitioners, policymakers, and researchers seeking to enhance productivity in the RMG industry and similar manufacturing sectors.

Customer Relationship Managemenet’s Impact on Customer Satisfaction and Perfo...Istanbul Beykent University (İstanbul Beykent Üniversitesi)
Many companies have perceived CRM that accompanied by numerous
uncoordinated initiatives as a technological solution for problems in
individual areas. However, CRM should be considered as a strategy when
a company decides to implement it due to its humanitarian, technological
and process-related effects (Mendoza et al., 2007, p. 913). CRM is
evolving today as it should be seen as a strategy for maintaining a longterm relationship with customers.
A CRM business strategy includes the internet with the marketing,
sales, operations, customer services, human resources, R&D, finance, and
information technology departments to achieve the company’s purpose and
maximize the profitability of customer interactions (Chen and Popovich,
2003, p. 673).
After Corona Virus Disease-2019/Covid-19 (Coronavirus) first
appeared in Wuhan, China towards the end of 2019, its effects began to
be felt clearly all over the world. If the Coronavirus crisis is not managed
properly in business-to-business (B2B) and business-to-consumer
(B2C) sectors, it can have serious negative consequences. In this crisis,
companies can typically face significant losses in their sales performance,
existing customers and customer satisfaction, interruptions in operations
and accordingly bankruptcym249-saw PMI To familiarize the soldier with the M249 Squad Automatic Weapon ...
M249 Saw marksman PMIThe Squad Automatic Weapon (SAW), or 5.56mm M249 is an individually portable, gas operated, magazine or disintegrating metallic link-belt fed, light machine gun with fixed headspace and quick change barrel feature. The M249 engages point targets out to 800 meters, firing the improved NATO standard 5.56mm cartridge. The SAW forms the basis of firepower for the fire team. The gunner has the option of using 30-round M16 magazines or linked ammunition from pre-loaded 200-round plastic magazines. The gunner's basic load is 600 rounds of linked ammunition. The SAW was developed through an initially Army-led research and development effort and eventually a Joint NDO program in the late 1970s/early 1980s to restore sustained and accurate automatic weapons fire to the fire team and squad. When actually fielded in the mid-1980s, the SAW was issued as a one-for-one replacement for the designated "automatic rifle" (M16A1) in the Fire Team. In this regard, the SAW filled the void created by the retirement of the Browning Automatic Rifle (BAR) during the 1950s because interim automatic weapons (e.g. M-14E2/M16A1) had failed as viable "base of fire" weapons.
Early in the SAW's fielding, the Army identified the need for a Product Improvement Program (PIP) to enhance the weapon. This effort resulted in a "PIP kit" which modifies the barrel, handguard, stock, pistol grip, buffer, and sights.
The M249 machine gun is an ideal complementary weapon system for the infantry squad platoon. It is light enough to be carried and operated by one man, and can be fired from the hip in an assault, even when loaded with a 200-round ammunition box. The barrel change facility ensures that it can continue to fire for long periods. The US Army has conducted strenuous trials on the M249 MG, showing that this weapon has a reliability factor that is well above that of most other small arms weapon systems. Today, the US Army and Marine Corps utilize the license-produced M249 SAW.
