Impact of Cost Problems (F5) on Implementation Problems (F2)
SISP can be very time-consuming and expensive [74]. The excessive cost of the
planning process can deter management from implementing the plan. The extended
duration (no. 32 in F5) and increased cost (no. 46 in F5) can result in a plan that is out
of date too soon. The duration and cost, along with the outdated plan, may not be in
accordance with top management's expectations (no. 15 in F2). Top management may
be unwilling to support implementation if the SISP process requires its excessive
involvement, especially in tedious tasks (such as defining strategic or other business
issues in minute detail) or technical tasks (such as evaluating detailed data models and
dataflow diagrams). Hence, top management may be incredulous about the plan and
reluctant to implement it (no. 16 in F2).
