A high failure rate of changes duringPost Implementation Review (PIR)inITIL’s change management process suggests a deficiency in theassessment and evaluation of change requests(A).

If this step is inadequate (e.g., overlooking conflicts or underestimating impacts), changes are more likely to fail, as they may not align with objectives or be poorly planned.

Insufficient budget (D):May limit implementation but is less likely the primary cause of failed objectives.
