Lean Analytics

Alistair Croll & Benjamin Yoskovitz

1st ed.

Startups don't die from lack of data, they die from lack of focus. This is how to find the one metric that actually matters right now and ignore the rest.

About the book

Croll and Yoskovitz's discipline is separating metrics that change a decision from numbers that merely flatter — a dashboard full of the latter feels like progress while telling you nothing about whether the riskiest part of the business is actually working. Their fix is the One Metric That Matters: a single number, chosen by knowing your business model and your current stage, that the whole team points at until it earns replacement. The book maps good-vs-vanity metrics and realistic benchmarks across business models and the five stages of a startup's life.

Best used for

  • —Picking the One Metric That Matters for your current stage and business model
  • —Auditing a dashboard for vanity metrics that flatter but don't change decisions
  • —Setting realistic targets and benchmarks instead of guessing at a number

“Amazing. Period. Full of 'meat', contentful and actionable from the next business day.”

— Maciek Wilczyński, Goodreads
