Notes
Elements and Performance Criteria
1. Determine the functional changes required
  • 1.1 Consult the user to determine, and document, the functional change required
  • 1.2 Clarify the impact of changes with operational personnel
2. Review legacy language
  • 2.1 Identify the basic structures of the legacy language
  • 2.2 Review the data storage of the legacy language with regard to global variables, modularisation, cohesion and coupling
  • 2.3 Review the basic algorithms of the legacy language
3. Identify and isolate the change
  • 3.1 Review the technical documentation for the system, to determine which modules to change
  • 3.2 Review the source code to determine program logic and flow
  • 3.3 Update the technical documentation to reflect the current state of the program
4. Determine the framework for change
  • 4.1 Determine the change approach to be used to implement the change
  • 4.2 Ascertain and detail the risks for each approach
  • 4.3 Determine the personnel who will make the changes
5. Design the change
  • 5.1 Develop the changes required, considering the impact of the changes on other parts of the system
  • 5.2 Document the changes according to change-management standards
6. Code the change
  • 6.1 Identify and obtain, the appropriate hardware and software for the change
  • 6.2 Write the code according to programming standards
  • 6.3 Compile and unit test the changes
  • 6.4 Document the changes according to programming standards
7. Test the change
  • 7.1 System test the changes and record the outcomes
  • 7.2 Perform user acceptance testing and record the outcomes
  • 7.3 Sign off the change request
8. Archive the system
  • 8.1 Create a new version of software, according to configuration management standards
  • 8.2 Archive the development system, including the source code, compilers and test data
