The deal is only 20% of the work. The remaining 80% is integration. Most M&A failures in the UK mid-market stem from a 'governance gap' where the due diligence findings are never operationalised. If your integration plan is a separate spreadsheet, you've already lost.

### What is Post-Merger Integration (PMI)?
**Definition:** Post-Merger Integration (PMI) is the complex process of combining and rearranging businesses to materialise the efficiencies and synergies that justified the deal. It requires a unified view of governance, systems, and people.

### Action List for Deal Success
- Use a unified platform for both due diligence and integration to ensure continuity of knowledge.
- Map target company risks directly into your GRC framework for immediate remediation.
- Ensure the board has real-time visibility on integration KPIs, not just deal costs.
