    • Determining budgets.
    • Gathering system requirements.
    • Detailed user documentation.
  • The SDLC initiates with a business need, it proceeds to satisfy that need and ends when system benefits would not at all be significant than maintenance cost.
  • The SDLC is comprised of seven phases that includes:
    • Planning
    • Analysis
    • Design

    • Testing
    • Implementation
    • Maintenance

Explanation of Solution

Most Critical Phase in SDLC:

  • All phases are important to build a social networking website, but the most critical phase in the System development life cycle is the maintenance phase.
  • During this phase, the organization performs corrections, changes and up gradations to ensure that system meets requirements.
  • Corrective maintenance would make system changes to flaws in design, errors in coding or issues in implementation.
  • Preventive maintenance would make system changes to reduce chances for system failure in future.
  • In this phase, the social network will grow, develop, attract users, and evolve depending on what the users prefer.
  • The success of the social network will be decided in this phase.
