When Corp Dev runs diligence and hands it off to integration, it creates information gaps. Having the integration leader run diligence provides irreplaceable firsthand context, preventing misinterpretations and avoiding the need to 're-diligence' the deal later.

Involve the integration lead early in the deal process to act as a 'red team.' Their role is to challenge the business case and probe the plan with practical, ground-level questions, preventing strategic 'echo chambers' and ensuring the deal is executable.

Cisco's model brings the integration lead in from the earliest phases to shape diligence strategy. This ensures the "how" of integration is validated early, preventing post-close surprises and accelerating value capture, a stark contrast to the traditional model where integration is a late-stage handover.

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.

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.

Deal models often flag redundant roles for cost savings. However, an integration leader can identify hidden value, such as crucial client relationships held by an administrative assistant. Cutting roles based purely on numbers can inadvertently destroy the very value the deal was meant to capture.

Progress builds its pre-LOI synergy models by focusing on high-conviction cost optimizations it can control, such as leveraging global centers of excellence and consolidating sales/back-office functions. Revenue synergies are treated as upside, not core to the valuation.

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.
