Study Notes
SDLC Methodologies
- Incremental Model is used when demand for an early release of a product arises, when the software engineering team is not very well skilled or trained, and when high-risk features and goals are involved.
- It is commonly used for web application and product-based companies.
- The advantages of the Incremental Model include:
- Quick generation of software during the software life cycle.
- Flexibility and low cost to change requirements and scope.
- Easy identification of errors.
- Less costly compared to others.
- Customer can respond to each building.
- The disadvantages of the Incremental Model include:
- Requires good planning and designing.
- Problems may arise due to system architecture.
- Each iteration phase is rigid and does not overlap each other.
- Rectifying a problem in one unit requires correction in all the units and consumes a lot of time.
Spiral Model
- The Spiral Model is a combination of the waterfall model and iterative model.
- Each phase in the Spiral Model begins with a design goal and ends with the client reviewing the progress.
- The Spiral Model was first mentioned by Barry Boehm in his 1986 paper.
- The development team in the Spiral-SDLC model starts with a small set of requirements and goes through each development phase for those set of requirements.
- The software engineering team adds functionality for the additional requirement in every-increasing spirals until the application is ready for the production phase.
Requirement Life Cycle
- Requirement Life Cycle involves several phases and can be a complicated process.
- The nature of the process depends on the methodology chosen for software development.
- Each phase may involve a lot of paperwork and approval procedures.
- It deals with project documents like a project proposal, project management plan, project scope, and the business case.
Phases of Requirement Life Cycle
- Phase 1: Requirement Definition (Requirement extraction)
- Phase 2: Requirement Validation (Analyzing the needs or conditions required to meet a new or altered product)
- Phase 3: Requirement Documentation (Formal written documents that outline the technical and logical requirements of a project)
- Phase 4: Requirement Management (Planning, monitoring, analyzing, communicating, and managing requirements)
Software Development Life Cycle (SDLC)
- SDLC is the sequence of activities carried out by developers to design and develop high-quality software.
- Different phases of SDLC include:
- Requirement Gathering
- Design Stage
- Build Stage
- Test Stage
Rapid Application Development (RAD) Model
- RAD model focuses on the reuse of templates, tools, processes, and code.
- Different phases of RAD model include:
- Business Modeling
- Data Modeling
- Process Modeling
- Application Generation
- Testing and Turnover
- RAD model is used when there is a need to develop software quickly and with a high degree of quality.
