Executive summary

A method for reviewing whether an integration is delivering the value it promised, on evidence that survives challenge.

What is inside

What the benefits review covers

The asset walks a review lead and finance partner through building the benefits register from the approved case, validating synergies against frozen baselines, applying attribution tests, measuring attrition above natural churn, building a variance bridge, re-forecasting the horizon, re-grading assumptions, and running a review that informs the major gate decisions. A worked synthetic case runs a month-12 review.

Reconciling an integration's results against its approved case
Why claimed synergies and attributed synergies differ
Attribution tests for market effects, double counting, and pre-deal initiatives
Measuring customer attrition above natural churn
A variance bridge across synergies, attrition, and one-time cost
Re-forecasting the remaining horizon and re-testing switching values
A review agenda that ends in continue, adjust, or re-appraise

How to use it

How teams use it

Teams use it at the major review points, typically month 12 and close. Finance owns the register and bridge, the measurement lead supplies validated figures, the IMO lead explains variances, and the sponsor decides with the steering group. Communities of practice use the attribution checklist to test each other's synergy claims.
