Measurement plan template: one KPI, a real target and a decision, on one page

A measurement plan should be agreed before the work starts, not assembled from whatever the dashboard shows afterwards. The version that works is short: one business goal, one number that proves marketing moved it, a target someone can say no to, and the decision you'll make if it isn't working.

Below are the eleven sections, what each one is for, the mistake I see most, and a line from a filled-in plan for a made-up coffee subscription launch. You can see the whole plan here, or start your own. It's free and there's no sign-up.

01

Business goal

The number the business actually cares about. Revenue, customers, retention, share. Not a marketing metric.

The usual mistake is writing a marketing metric here, like awareness or engagement. Write the number the business reports on.

ExampleGrow subscription revenue from 4% to 10% of total coffee revenue by the end of Q1.

Push harder: Would the CFO recognize this as a goal?

02

What marketing has to change

The behavior or belief that moves the goal, written as from, to.

"Drive consideration" isn't a change. From what, to what is. It also tells you what to count.

ExampleFrom buying a bag when they remember, to setting up a subscription after their first order.

Push harder: What exactly do they do today, and what should they do instead?

03

Whose behavior has to change

The specific people. The rest of the plan only counts what they do.

If you can't find these people in your data, you can't measure what they did. Define them the way the report does.

ExampleFirst-time online buyers in their first 30 days, plus retail buyers who scan the insert in the bag.

Push harder: Who is left out on purpose?

04

The one number

One primary KPI, and exactly how it's counted.

Three KPIs means no KPI. Pick one, then write down exactly how it's counted so nobody argues in month two.

ExampleSubscription starts: new active subscriptions created in the period, not counting reactivations.

Push harder: Is it one number?

05

Where it is today

The current number, the date range, and where it came from.

Most plans skip this, and then every result looks good. Write the number, the dates, and the report it came from.

Example38 starts a month, averaged over June to August, from the Shopify subscriptions report.

Push harder: Over what dates?

06

Target and deadline

From what, to what, by when. And how you picked it.

A target without a reason gets negotiated down at the first bad week. Say how you picked it.

Example150 starts a month by the end of January. Set from 8% of monthly first-time buyers converting, which is what the best week this summer did.

Push harder: Why this number and not half or double?

07

Early signals

Two or three things you'd see in the first two weeks if it's working.

The KPI usually moves too slowly to steer by. Early signals are what you'll actually watch in the first two weeks.

ExampleInsert QR scans over 2% of bags shipped. Welcome email 2 click rate over 6%. Subscription page to checkout over 20%.

Push harder: What would you see in week two that tells you to keep going?

08

Guardrails

Numbers that must not get worse while you chase the target.

Targets get hit in ways nobody wanted: discounts that wreck margin, sign-ups that cancel. Name the numbers that must hold.

ExampleOne-time order revenue doesn't drop more than 5%. Cancellations in the first 60 days stay under 25%.

Push harder: What could you break while hitting the target?

09

Where the numbers come from

The tool or report for each number, and who pulls it.

When two tools disagree, the meeting becomes about the tools. Decide the source for each number now, and who pulls it.

ExampleStarts and cancellations: Shopify subscriptions report, pulled by Dana. Email clicks: Klaviyo. QR scans: link tracker, pulled by Sam.

Push harder: Who pulls each number, by name?

10

Who looks, and how often

The meeting or report, the owner, and the rhythm.

Numbers nobody looks at stop being collected. Put them in a meeting that already exists, with an owner.

ExampleMonday growth standup, 15 minutes, Dana owns the numbers. Monthly review with the client on the first Tuesday.

Push harder: Which meeting does this show up in?

11

What we'll do if

The decision you agree on now, before the numbers come in.

This is the section that makes it a plan and not a report. Agree now what you'll change if the number is short by a date.

ExampleIf starts are under 70 a month by week six, we move budget from paid social to the insert and the welcome flow. If cancellations pass 25%, we pause acquisition and fix onboarding first.

Push harder: What number, by what date, changes the plan?
