Why integration value is won or lost after close

The deal model and the integration plan are often built by different teams on different timelines. PwC found only 46% of respondents fully translated value drivers into initiatives with clear owners, timelines, and dependencies before integration. 

Bring integration team members in early on what the deal should deliver, and start discovery across both organizations so each side understands how the other operates and where every workstream stands. 

Integration work also crosses functions. For example, changing a payroll provider touches HR, finance, and technology at once. Regular cross-functional working sessions surface those dependencies early, before they cause delays. 

Recommendation: Agree on the integrated end state for each function, map the dependencies between them, and give every synergy an owner, a timeline, and a metric. 

Integration decisions shape the combined business for years. Momentum matters, but a rushed decision that overlooks how the acquired company works often gets revisited later, at a higher cost. 

Strong governance balances both: seek to understand different points of view, take the time to get key decisions right, then make them clearly and keep moving. 

Recommendation: Stand up an integration management office (IMO) with guiding principles, decision rights, and a functional, cross-functional, and executive cadence. Define escalation paths and communicate each decision so teams can act on it. 

Deal value often walks out the door in two ways: key employees leave, and key customers start shopping. Often, both start with silence. When people don’t hear what’s changing, they fill the gap with assumptions. 

Communication is the first line of defense. Employees, customers, and vendors each need to hear what’s changing, what isn’t, and when they’ll know more. Consistent messages from leaders throughout the integration process also ease cultural friction. 

Recommendation: Build a pre-close communication plan that sequences messages by audience, from leadership and employees to customers and vendors. Pair it with retention plans for critical talent and key accounts. 

A green project dashboard doesn’t mean the deal is delivering. PwC found 62% of successful acquirers were very confident their reported synergies were real and auditable, compared with 27% of limited-success acquirers. 

Recommendation: Measure realized run-rate synergies against the deal model. Build targets into business unit budgets, and keep governance in place until synergies show up in the financials.
