Who This Helps
This is for junior analysts who want to stop guessing and start shipping analysis that actually moves the needle. You're tired of running experiments that don't matter. You want to be the person whose recommendations get a "yes" from stakeholders.
Mini Case
Mei, a junior analyst at a mid-size e-commerce company, had 12 experiment ideas on her backlog. She picked the one that felt easiest: a button color test. It took 3 weeks to run and moved conversion by 0.2%. Meanwhile, a pricing experiment she skipped would have boosted revenue by 8% in 7 days. Ouch.
Mei learned that prioritization isn't about what's easy. It's about impact. She joined the Data Reliability Leadership course to build a system for choosing the right experiment every time.
Do This Now (5 Steps)
- List your experiment ideas. Write down every test you're considering. Don't filter yet.
- Score each by potential impact. Use a simple scale: low (1), medium (3), high (9). Think about revenue, retention, or time saved.
- Score each by effort. How many hours will it take? Low effort (1), medium (3), high (9). Be honest.
- Calculate priority score. Divide impact by effort. The highest number wins. This is your north star.
- Pick the top one and start today. No more analysis paralysis. Ship the experiment with a clear recommendation on what you'll measure.
Avoid These Traps
- Falling in love with a hypothesis. Just because you think something will work doesn't mean it will. Let the data speak.
- Ignoring stakeholder input. Your boss might have a pet project. Listen, but use your priority score to guide the conversation.
- Overcomplicating the score. Don't build a spreadsheet with 20 columns. Keep it simple so you actually use it.
- Waiting for perfect data. You'll never have perfect data. Use what you have and move forward.
- Forgetting to document your reasoning. Write down why you picked this experiment. Future you will thank you.
Your Win by Friday
By Friday, you'll have a prioritized list of experiments and one clear recommendation to share with your team. You'll feel confident that you're working on the highest-impact move. And you'll have a repeatable system for next week. That's a win you can build on.
And hey, if you nail this, maybe your boss will finally stop asking "why did we run that test?"
