Turn agreements into action with the Rule of Three and implementation How’s

Hard - Requires significant effort Recommended

A startup COO agreed in principle to a vendor’s analytics package. In past deals, that verbal Yes had crumbled during legal review. This time, the account lead slowed down and asked, “What about this makes it a good idea for your team?” The COO described how the tool would cut reporting time in half. The lead summarized the goal and the risks, and the COO said, “That’s right.”

The lead then asked three How questions: “How will we measure progress in the first 30 days?” “How will we handle it if adoption lags?” and “Who else needs to be involved?” The COO named a skeptical finance director and proposed two check‑ins with usage targets. The lead noted the pronouns, hearing we and they, and scheduled a call with finance before contracts started flying.

Through implementation, the team followed the agreed metrics and sent a weekly one‑pager. When adoption dipped in week two, they used the pre‑agreed plan: a short training clinic and simplified dashboard. Because the signals were clear, no one panicked. The contract stuck, and the relationship strengthened.

The Rule of Three works because repeated confirmation in different forms uncovers weak Yes responses and surfaces hidden stakeholders before they derail you. Pair that with concrete How questions and attention to pronouns and tone, and you turn a meeting into a shared plan that survives contact with real life.

After your next tentative Yes, ask, “What about this makes it a good idea?” and listen for their logic. Follow with a tight summary until you hear, “That’s right.” Then nail three implementation How’s: how to measure progress, how to handle slippage, and who else must be involved. Watch for pronouns and hesitation that signal hidden decision‑makers, and bring those people in before paperwork. Close by sending a one‑page recap with owners and dates. Try this on one deal this week and see how much smoother execution feels.

What You'll Achieve

Internally, you’ll stop celebrating early and start building durable plans. Externally, you’ll reduce rework, prevent surprise blockers, and increase follow‑through on agreements.

Test commitment three different ways

1

Get verbal alignment

After a proposal, ask, “What about this makes it a good idea?” Listen for their reasoning in their words.

2

Summarize to That’s right

Reflect their goals and risks until they say, “That’s right.” This marks true buy‑in.

3

Lock implementation with How

Ask, “How will we measure progress?” “How will we handle it if we slip?” and “Who else needs to be involved?” Capture owners and dates.

4

Watch pronouns and tone

Lots of I/me from them can mean they lack authority. Look for we/they/them to spot unseen stakeholders you must engage.

Reflection Questions

  • Where did a quick Yes fall apart last quarter—and why?
  • Which three confirmations will I secure before moving forward?
  • What metrics and check‑ins will prove momentum?
  • Who is behind the table and how will I include them early?

Personalization Tips

  • Project work: Before leaving a kickoff, get three confirmations and a written timeline with owners, then send a one‑page recap.
  • Hiring: After a verbal offer, ask, “How will you and I know the first 90 days were a success?” and write it into the plan.
