Build a mutual action plan the buyer will actually co-own

I want to build a mutual action plan for Larkspur Financial Group to actually get us to a signed deal by September 30, 2026, not a one-sided deadline sheet I hand them and hope they follow.

What we sell: a fraud-detection platform for mid-size banks. Milestones we already know need to happen, from either side: a security review, a pilot with two branches, and CFO budget sign-off. Who's involved on both sides so far: our implementation lead and their IT director on the technical side; their CFO and our AE on the commercial side. Risks already visible in how this deal has gone so far: their IT director mentioned being short-staffed through the next two months.

BUILD THE PLAN
List every milestone between now and signature, on both sides, not just the ones on our side — a mutual action plan that only tracks what we owe them isn't mutual, it reads as a project plan for their benefit only, and a real one has clear obligations on the buyer's side too: internal stakeholder reviews, security or procurement steps, budget approval, whatever a security review, a pilot with two branches, and CFO budget sign-off and the deal's nature actually require. For each milestone: a target date worked backward from September 30, 2026, not forward from today (working backward surfaces whether the timeline is actually realistic before committing to it), an owner named from our implementation lead and their IT director on the technical side; their CFO and our AE on the commercial side — never "TBD" or an unowned milestone, since an unowned step is the single most common place a mutual action plan quietly stalls — and any milestone it depends on finishing first.

DEPENDENCY FLAGS
Call out explicitly any milestone that depends on a step owned by the other side finishing first, since dependency chains crossing between the two organizations are where mutual action plans most often break down silently — our side waiting on their internal approval, with neither side proactively checking in on it, is a specific and common failure this plan needs to make visible rather than hide inside a flat list.

RISK-DRIVEN ADJUSTMENTS
Given their IT director mentioned being short-staffed through the next two months, flag which milestone in the plan is most likely to slip, and build in one specific buffer or check-in point around it rather than pretending the plan will execute exactly as drafted.

HOW TO PRESENT IT
Write one short paragraph of framing language for introducing this plan to our implementation lead and their IT director on the technical side; their CFO and our AE on the commercial side that positions it as something built together in the next conversation, not something delivered as a finished document — a mutual action plan the buyer had no hand in shaping tends to get treated as the vendor's homework rather than a shared commitment, and the framing should invite them to adjust dates or add missing steps rather than simply asking them to sign off on what's already been decided.

OUTPUT FORMAT
1. The full milestone table: milestone, owner, target date, dependency.
2. The dependency flags.
3. The risk-driven adjustment and where the buffer goes.
4. The framing paragraph for introducing it.
