Post-investment review

A scheduled comparison of what an approved project was expected to deliver with what it delivered, and what that teaches.

The deliverable

What it is

Reviews are skipped because they look backwards at a decision nobody can change. Their purpose is forwards: consistent optimism about cost, benefit or timing shows up across several reviews and can then be corrected in future appraisals.

The review is about the quality of the forecast, not the people who made it. Where it becomes a search for blame, sponsors learn to present cautious figures and the appraisals lose their value.

Look for the pattern across reviews. One variance is a project; the same variance five times is a forecasting habit.
