OBJECTIVE 3: PROGRAM MODIFICATION
When a program change is submitted for approval, a list of all required updates should be compiled by management and program users.
Changes should be thoroughly tested and documented.
During the change process, the developmental version of the program must be kept separate from the production version.
When the amended program has received final approval, it should replace the production version.
Changes should be implemented by personnel independent of users or programmers.
Logical access controls should be employed at all times.
