What it means
A post-implementation review compares the outcome of a project or investment against what was expected, some months after completion.
Why it matters
Without it, the case made for an investment is never tested, and the same optimistic assumptions get used again.
What it looks like in practice
Compare against the original business case: the benefits claimed, the costs forecast, and the timescale. Record what would be done differently.\n\nDo it late enough for benefits to have appeared — usually six to twelve months.

Where to get proper advice
Your own figures.
