Welcome » IT Booklets » Development and Acquisition » Maintenance » Major Modifications
Major modifications include significant functional changes to an
existing system, converting to a new system, and introducing new
systems or data due to corporate mergers or acquisitions. Major
modifications should be implemented following a well-structured
process similar to the SDLC (systems development life cycle)
described in the "Development" section.
Major modification standards should address applicable project
activities such as requirements analysis, feasibility studies,
project planning, software design, programming, testing, and
implementation procedures. Refer to the "Project Management" and
"Development" sections for additional project management details.
Refer to the "Conversion" discussion later in this section for
specific considerations relating to major modifications.
