Post-merger integration

What needs to be in place on Day 1, and who owns the synergy that looks good on paper?

The deal thesis is never translated into what actually needs to change, for whom, and when. Day 1 and Day 100 aren't sharply defined. Synergies are sized on what's theoretically possible, not on what's been assigned to an owner with a timeline. Roles stay unclear across two organizations, and the people carrying the value leave in the months when that uncertainty is greatest.

1

Synergy baseline

For each synergy: source, owner, timeline and a testable assumption, built through templates and a wizard.

2

Day 1 and Day 100 plan

A checklist dataset for Day 1 and a Day 100 plan that puts the heaviest decisions first.

3

Integration office dashboard

Benefit tracking per synergy, a decision forum agenda, dependencies and a key-person risk list.

What it delivers

The front door provides three generators: a synergy baseline in which every synergy gets a source, owner, timeline and testable assumption, a Day 1 plan as a checklist dataset covering legal structure, contracts, payments, access and communication, and a Day 100 plan in which the tool sorts decisions by the cost of uncertainty. After that, the integration office itself functions as a tool: benefit tracking per synergy with status indicators and timers, a decision forum agenda, visible dependencies and a key-person risk list based on role, not on judgment. For sequential acquisitions, the standard 100 days can be saved as a reusable configuration. There's a standard question per component on what to integrate and what not to, because integrating can also destroy value.

How it works

Deal intake

Thesis, value sources and entities are recorded.

Synergy baseline wizard

Every synergy gets a source, owner, timeline and testable assumption.

Day 1 and Day 100 generators

The checklists and the decision-by-cost-of-uncertainty plan are built.

Integration office dashboard

Timers and benefit tracking continue through to the monthly recalibration.

What this explicitly is not

  • No completed engagement as reference There is no fully completed PMI engagement to point to yet; the tool structures, it does not prove a track record.
  • No promise at the synergy level The baseline makes assumptions testable; it does not guarantee synergy realization.
  • No judgment about people The key-person risk list is role-based and contains no assessments.

Three outcomes

Every report ends in three routes. You choose; we deliver the analysis, not the engagement.

1

Do it yourself

Do it yourself: the three documents and the dashboard, with templates for decision forums and communication.

2

Partly guided

Partly guided: a partner for organizational design and culture and leadership, while the tool remains the record.

3

Outsource it

Outsource: a full integration office, staffed by the partner, running on your own system.

The next step

The bridge to the work scan

Merging two organizations means two sets of tasks side by side. The FTE TO AI work scan can run across both organizations to see where the combined headcount can land and which part AI can carry — the FTE calculation as a synergy instrument.
