Post-Merger Integration Work Breakdown Structure

This is a practical guide to building a work breakdown structure for a post-merger integration project — a deliverable-oriented decomposition of the whole scope into manageable work packages, adapted to the realities of integrating two organisations after a deal.

What a Work Breakdown Structure is

A work breakdown structure is a deliverable-oriented decomposition of the whole scope into manageable work packages. For the full concept and how it works in general, see Work Breakdown Structure. On a post-merger integration project it plays the same role, tuned to this kind of work.

Why it matters for a Post-Merger Integration project

Post-Merger Integration projects live or die on integrating two organisations after a deal. A well-built work breakdown structure 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 post-merger integration projects drift into avoidable delay and cost.

What to include

  • Top-level deliverables
  • Sub-deliverables
  • Work packages (8–80 hours)
  • WBS numbering
  • WBS dictionary entries

Post-Merger Integration-specific considerations

Tailor the work breakdown structure to the risks that most often derail post-merger integration projects:

  • Systems and process consolidation
  • People and culture
  • Realising synergies

Example

On a real post-merger integration project, the work breakdown structure would be shaped by integrating two organisations after a deal. In particular, it should explicitly account for the project’s biggest risks — systems and process consolidation, people and culture, realising synergies — rather than treating them as afterthoughts.
