7. Testing, Evaluating and Maintaining

This is the fifth and final stage of the Software Development Lifecycle (SDLC).

Unlike the previous states of the SDLC, aspects of this final stage continue throughout the life of the system.

Tasks included in this stage include:

  • Testing to ensure the system meets requirements
  • Trialling and using the Operations Manual
  • Ongoing evaluation to monitor performance
  • Ongoing evaluation to review the effect on users, participants and other people within the environment
  • Maintaining the system to ensure it continues to meet requirements 
  • Modifying parts of the system where problems are identified.

Students Learn About:


testing, evaluating and maintaining

  • testing and evaluating the solution with test data such as
    • volume data
    • simulated data
    • live data
  • checking to see that the original system requirements have been achieved
  • trialling and using the operation manual
  • reviewing the effect on users of the information system, participants and people within the environment
  • modifying parts of the system where problems are identified

Students Learn To:




  • compare the new system to the old and evaluate whether the requirements have been met
  • update system documentation
