Phase 1: Pre-Close Preparation (Days -30 to 0)

Integration planning should start before the deal closes. Use this time to build the foundation for success.

  • Form integration team: Dedicated team with clear authority
  • Conduct due diligence: Identify integration risks and synergies
  • Develop integration strategy: Define approach and timeline
  • Prepare communication plan: Messages for employees, customers, partners
