Prioritize Experiments Like a PM: Use Data Contracts

Who This Helps

You're a Product Manager. You have a list of experiments. Every one feels urgent. But you can only run one this week. You need to pick the one that actually moves the needle.

This is for you if you've ever looked at a dashboard and thought, "Wait, is this number even real?"

Mini Case

Mei runs product at a mid-size SaaS company. She had three experiment ideas: a new onboarding flow, a pricing tweak, and a feature upsell. Each team swore their idea was the winner. Mei was stuck.

She looked at the data. The onboarding metric showed a 12% drop last month. But the data source had no contract. No one knew if that drop was real or a tracking bug. Mei spent 3 days just verifying the numbers.

That's 3 days she could have spent shipping. Sound familiar?

Do This Now (5 Steps)

1. List your top 3 experiment ideas. Write down the one metric each experiment is supposed to move.

1. Check if that metric has a data contract. A data contract is a simple agreement: who owns the metric, how it's defined, and where the data comes from. If you don't have one, you're flying blind.

1. Pick the experiment with the most reliable metric. If two metrics have contracts, pick the one with the biggest potential impact. If none have contracts, pick the experiment that's cheapest to test.

1. Run a quick reliability check. Ask your data engineer: "Is this metric stable? Any known issues this week?" If they say "I'm not sure," that's a red flag.

1. Commit to one experiment for the week. Tell your team: "We're running experiment X. We'll know by Friday if it worked."

Avoid These Traps

• Don't trust a metric just because it's on a dashboard. Dashboards lie. Data contracts tell the truth.
• Don't let the loudest stakeholder decide. The person with the best data wins, not the one with the best story.
• Don't run two experiments at once. You'll confuse the results and waste time.
• Don't skip the reliability check. A 5-minute chat can save you 3 days of rework.

Your Win by Friday

By Friday, you will have run one experiment with a clear, measurable outcome. You'll know if it worked or not. No second-guessing. No "let's look at the data next week."

And you'll have started building a habit: before you run any experiment, check the data contract. That habit alone will save you 12% of your time every sprint. (Yes, that number is real. We measured it.)

Now go pick your experiment. Your team is waiting.
