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.

Learn about the different phases of the software development lifecycle including project initiation, requirements analysis, and design. Explore activities involved in each phase from gathering stakeholder requirements to creating a blueprint for the software.
