Merger & Acquisition Decision Log

This is a practical guide to building a decision log for a merger & acquisition project — a record of the key decisions made, by whom and why, adapted to the realities of planning and executing an acquisition and integration.

What a Decision Log is

A decision log is a record of the key decisions made, by whom and why. For the full concept and how it works in general, see Decision Log. 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 decision log 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

  • Decision
  • Date and owner
  • Rationale
  • Alternatives considered
  • Impact

Merger & Acquisition-specific considerations

Tailor the decision log 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 decision log 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.
