Typical Stages of a development or maintenance project using SDLC methodology during ‘Design, Construction and Implementation Phases’
  • Impact Analysis of existing applications / systems.

  • Pull existing version of source or create a new program using change management software.

  • Modify the source or create new programs.

  • Compile the source program or put back the source in change control management.

  • Compile until there are no errors.

  • Pull Production JCLs and customize for unit Testing or Create Test JCLs for new programs.

  • Create Test Files, and associated documentation like Test Grids, etc.

  • Execute test JCLs.

  • Validate results and if they are not as expected, Modify source, Compile and Test program.

  • Once Test are OK, document the results, code compares etc.

  • Create or Modify Production JCLs and put back in the change management system.

  • Repeat above steps for String Test, UAT, SIT, Regression and Performance Testing etc.
