How Strategy, Due Diligence, And Integration Fit Together
1) Strategy And Thesis
Write the one-page case: where value comes from, what must be true, and the no-go list. Choose programmatic pacing or selective large bets, using market and capital signals BCG, McKinsey.
2) Due Diligence That Proves The Case
- Commercial. Customer segments, share, pricing power, and churn.
- Operational. Cost baselines, footprint, and service metrics.
- Technology and data. Scalability, integrations, and security.
- Regulatory. Market, data, trade, and labor issues.
Teams are using gen AI to scan more sources and synthesize faster, while experts validate sources and assumptions Bain.
3) Integration That Captures Value
Define the target operating model early, set Day One decisions, and track synergies weekly. McKinsey notes that top-quartile programs often identify 30% to 150% more synergy potential than initial diligence estimates when integration is rigorous McKinsey.
A 90-Day Starter Plan
