The Software Development Process

We have now gone through the various phases in the process of writing a software. These phases can be summarised as follows:

  1. What (Analysis)

  2. How (Design)

  3. Do It (Implementation)

  4. Test (Testing and Debugging)

  5. Use (Operation or Deployment)

  6. Maintain (Refinement)


A recommended way of writing programs is the procedure we have followed in creating the backup script - Do the analysis and design. Start implementing with a simple version. Test and debug it. Use it to ensure that it works as expected. Now, add any features that you want and continue to repeat the Do It-Test-Use cycle as many times as required. Remember, 'Software is grown, not built'.
