What is the Life Cycle of SDLC?

In the realm of software development, understanding the life cycle of SDLC (Software Development Life Cycle) is crucial for delivering high-quality products efficiently. This article delves into the stages, methodologies, and best practices that define SDLC, offering a comprehensive guide to navigating this critical process.

What is the Life Cycle of SDLC?

The SDLC, or Software Development Life Cycle, outlines the process of developing software from inception to deployment and maintenance. It encompasses several phases that ensure systematic progress and effective project management.

Phases of SDLC

  1. Planning Phase
    • Objective: Define project goals, scope, and requirements.
    • Activities: Conduct feasibility study, define project milestones.
    • Key Deliverables: Project plan, feasibility report.
  2. Analysis Phase
    • Objective: Gather and analyze end-user requirements.
    • Activities: Conduct interviews, create use cases and scenarios.
    • Key Deliverables: Requirement specification document.
  3. Design Phase
    • Objective: Design architecture and system specifications.
    • Activities: Develop system design, create prototypes.
    • Key Deliverables: System design document, prototypes.
  4. Development Phase
    • Objective: Build and code the software system.
    • Activities: Writing code, unit testing, integration testing.
    • Key Deliverables: Executable software.
  5. Testing Phase
    • Objective: Validate the software for quality assurance.
    • Activities: System testing, acceptance testing, bug fixing.
    • Key Deliverables: Test cases, defect reports.
  6. Deployment Phase
    • Objective: Release the software for user access.
    • Activities: Installation, data migration, user training.
    • Key Deliverables: Deployed software system.
  7. Maintenance Phase
    • Objective: Enhance and support the software post-deployment.
    • Activities: Bug fixes, updates, user support.
    • Key Deliverables: Maintenance documentation, updated software.
