Why it’s on the shelf

The book that turns innovation from a lottery into a discipline, by revealing the one question every winning product answers: what job did the customer hire it to do?

Two of the ideas you’ll keep

The Clif summary of Competing Against Luck pulls out 7 insights. Here are the first two.

  1. A **Job to Be Done** is the progress a person is trying to make in a particular **circumstance**, and it always has **functional, social, and emotional** dimensions. Nail the whole job, not just the functional features, and you become nearly impossible to copy.
  2. **Customers don't buy products; they hire them to do a job**, and when a better candidate appears, they fire the old one. Your real competition is defined by the job, not your product category: a milkshake competes with bananas, bagels, and boredom, not other milkshakes.
