The payroll system that Brigcttc is implementing might, for instance, need to be adjusted if the staffing structure at the college is reorganized.

Other, internal, changes will crop up. Amanda might find that there are inconsistencies in the program specifications that become apparent only when the programs are coded, and these would result in amendments to the specifications.
