Study Notes
Software Development Life Cycle (SDLC)
- SDLC methodologies provide a systematic process to guide the development team through various phases, ensuring that the software is well-planned, efficiently constructed, thoroughly tested, and effectively deployed.
Phases of SDLC
- A series of distinct stages or phases that define the tasks and activities to be performed during the software development process.
- Common phases include:
- Project initiation, feasibility analysis, resource planning, and initial risk assessment
- Requirements analysis: gather and document detailed requirements from stakeholders
- Design: create a blueprint for the software based on the requirements
- Implementation (coding): transform the design into executable code
- Testing: validate and verify that the software meets the specified requirements
- Deployment: release the software for end-users or clients
- Maintenance: sustain and enhance the software over time
Life Cycle Methodologies
- Life cycle methodologies, often referred to as SDLC methodologies, are structured approaches or frameworks used in the development, deployment, and maintenance of software applications.
- The choice of a specific life cycle methodology depends on factors such as the nature of the project, organizational preferences, and project requirements.
Waterfall Methodology
- A widely used project management method with a linear approach.
- Each stage of the workflow needs to be completed before moving on to the next step.
- Suitable for projects where the objectives are clearly outlined from the beginning.
- Best suited for projects with well-defined and stable requirements, particularly when a quick initial delivery is more critical than long-term maintainability.
Advantages of Waterfall Methodology
- Quick initial delivery: allows for the rapid development of a working version.
- Flexibility: provides flexibility to adapt to changing requirements, as changes can be made at any stage of development.
