To ensure Day 1 alignment and retain key talent, treat integration planning as a collaborative process. Share the developing integration plan with the target's leadership during due diligence. This allows them to validate assumptions, provide critical feedback, and feel like partners in building the future company, rather than having a plan imposed on them.

Contrary to standard M&A practice where integration begins post-close, Brad Jacobs makes immediate, unrestricted access to a target company's employees and operations a non-negotiable term upon signing. This allows his team to begin the integration process weeks or months earlier.

To maintain momentum, Cisco makes critical integration decisions—like site strategy or system consolidation—during diligence, not after close. These decisions are embedded into the final deal commitment materials, preventing post-close paralysis and emotional debates, allowing teams to execute immediately.

To avoid a broken handoff, embed key business and integration experts into the core deal team from the start. These members view diligence through an integration lens, validating synergy assumptions and timelines in real-time. This prevents post-signing surprises and ensures the deal model is operationally achievable, creating a seamless transition from deal-making to execution.

Many M&A teams focus solely on closing the deal, a critical execution task. The best acquirers succeed by designing a parallel process where integration planning and value creation strategies are developed simultaneously with due diligence, ensuring post-close success.

Don't surprise an acquired company with an integration plan on day one. Snowflake turns diligence into a collaborative process post-term sheet. They work with the target's leadership to jointly build the integration thesis, define milestones, and agree on charters, ensuring buy-in and alignment before the deal is even signed.

Pre-close diligence provides an incomplete picture due to legal and access limitations. The first 30 days post-acquisition represent the real discovery phase. This is when the integration team gains full access to financials, customer data, and systems, allowing them to validate assumptions and refine plans based on complete information.

To avoid post-close surprises and knowledge loss, marry diligence and integration leads before an LOI is even signed. This ensures real-world operational experience informs diligence from the start. The goal is to have a drafted integration thesis by LOI and a near-complete plan by signing, not after closing.

A process where the deal team hands off a signed transaction to a separate integration team is flawed. State Street integrates business and integration experts into the deal team from the start. This ensures diligence is informed by integration realities, timelines are realistic, and synergy assumptions in the deal model are achievable.
