The benefits of undertaking review processes (and the feedback arising from these processes) are:
- In the delivery step, cases can be identified where expected costs and benefits may not be realised, and corrective action developed.
- Future decisions can take account of lessons from past experience (see Figure 1).
- As a result, the effectiveness of future decisions (from planning to delivery) can be enhanced.
- These processes enable stakeholders to be provided with evidence-based explanations of why actual outcomes may have varied from expected outcomes.
