Although the program stages used by CIPP indicate that the evaluation should focus on the· stage of the program and that different questions arise at different stages, another advantage of the approach is that it encourages managers and evaluators to think of evaluation as cyclical, rather than project based.
Like performance monitoring, evaluating programs at each stage can provide a "continual information stream to decision makers to ensure that programs continually improve their services" (Alkin & Christie, 2004, p. 44, analyzing the CIPP approach).
