The reaurn on investment for Information Systems Developmentprojects takes place during the period of stability following the system's implementation. This return on investment can be leveraged by extending the period of stability or reducing the ongoing costs of maintenance and enhancement. Since the usefulness of information systems is dependent on their alignment with the organization's goalsandobjectives,theabilityofasystemtoabsorbchangedirectlyaffectsitslifespan.
