Merger & Acquisition Lessons Learned
This is a practical guide to building a lessons learned for a merger & acquisition project — what went well and badly, captured to improve future projects, adapted to the realities of planning and executing an acquisition and integration.
What a Lessons Learned is
A lessons learned is what went well and badly, captured to improve future projects. For the full concept and how it works in general, see Lessons Learned. On a merger & acquisition project it plays the same role, tuned to this kind of work.
Why it matters for a Merger & Acquisition project
Merger & Acquisition projects live or die on planning and executing an acquisition and integration. A well-built lessons learned gives the team a shared, explicit reference for exactly that — reducing ambiguity, aligning stakeholders, and making problems visible early enough to act. Skipping it, or doing it generically, is how merger & acquisition projects drift into avoidable delay and cost.
What to include
- What happened
- Impact
- Root cause
- Recommendation
Merger & Acquisition-specific considerations
Tailor the lessons learned to the risks that most often derail merger & acquisition projects:
- Cultural clash and attrition
- Integration complexity
- Synergies that never land
Example
On a real merger & acquisition project, the lessons learned would be shaped by planning and executing an acquisition and integration. In particular, it should explicitly account for the project’s biggest risks — cultural clash and attrition, integration complexity, synergies that never land — rather than treating them as afterthoughts.
