Phase 2—Change Planning
If the change was requested by another person or group (other than the person or group
responsible for change control), the person or group responsible for change control
should perform the following tasks:
•
Verify that the information provided about the proposed change is correct.
•
Submit a list of requirements to the person or group that requested the change.
Requirements usually include the following:
•
All application changes should be tested on a development system to ensure that
the changes work as described and do not disrupt the system. Determine who
should test the changes (developers, a separate testing group, or operations staff)
and ensure that some type of quality-control policy is established and adhered
to.
•
All changes should pass user-acceptance testing.
•
All test results should be handed over to change control.
•
All affected documentation should be changed and given to change control for
approval. Documentation includes new or changed error messages, new or
changed procedures, updates to internal operator guides, and the names of
changed or added files and the location of those files.
•
Users should verify and formally approve all data changes to ensure the integrity
of production data.
•
All naming conventions and other company standards should be followed.
•
A recovery plan with written instructions should be developed in case the
change does not work.
•
The requesting group should provide installation instructions if special
procedures are needed.
•
After submitting a list of requirements to the requesting group, the person or group
responsible for change control should make sure that the requirements are fulfilled
before implementing the change.
