Acquisitions rarely fail because of the deal terms. They fail — or underperform — because of what happens after closing: two teams, two cultures, and two sets of priorities that need to become one functioning organization without losing momentum.
I've been on the inside of this exact challenge, leading post-acquisition integration as a COO in a private equity-backed company. That experience is why I focus as much on operating discipline during integration as on the plan itself — clear ownership, a shared meeting rhythm, and accountability that holds while two organizations become one.
EOS provides the operating system that makes that integration real instead of aspirational. See EOS Implementation for the full process.
