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.

Combining strategy, M&A, and integration under a single leader provides a full lifecycle, enterprise-wide view. This structure breaks down silos and creates a "closed-loop system" where post-deal integration performance and lessons learned directly feed back into future strategy and deal theses, refining success metrics beyond financials.

Cisco moved from a dysfunctional "throw it over the wall" M&A model to an integrated one. The key change was implementing quarterly reviews where the integration team reports back to the original deal team on progress and synergy attainment. This forces dealmakers to learn from the downstream consequences of their strategies.

An M&A lead's primary skill isn't deep expertise in every domain, but the ability to assemble and manage a team of specialists (tax, IT, ops). They must know enough to spot issues and deploy the right expert, coordinating findings to assess valuation and integration hurdles, much like a general contractor on a build site.

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.

Cisco's integration team partners with corporate development to formulate a multi-faceted integration strategy aligned with the deal thesis before an LOI. This initial plan is a critical component of the first-stage approval conversation with the CFO, which greenlights negotiations.

An M&A lead's role isn't to be an expert in tax or IT, but to assemble specialists. Like a general contractor, they must know enough to spot issues ('wires sticking out of the wall') and deploy the right expert, synthesizing findings to assess valuation and integration hurdles.

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.

To prevent knowledge gaps between deal execution and integration, IFS makes the same internal expert responsible for a specific workstream (e.g., product, GTM) during commercial diligence and the subsequent integration phase, creating end-to-end accountability.
