Competing Against Luck: The Story of Innovation and Customer Choice

Clayton M. Christensen, Taddy Hall, Karen Dillon, David S. Duncan · HarperBusiness Paid Intermediate

When you feel that something is broken but cannot name it, Christensen's Jobs-to-be-Done lens gives you a way to describe the actual progress a person is trying to make in a specific situation. That reframing turns a fuzzy hunch into a concrete job you can go test with real people, which is exactly the move from vague to sharp. It is the canonical text on the idea, and it is a starting point for thinking in jobs, not a formula to follow blindly.

• People do not buy products, they hire them to make progress in a specific circumstance, so define the job, not the demographic.
• A job has functional, social, and emotional dimensions, which is often where the real, unmet problem is hiding.
• Once you can state the job clearly, you have a testable claim you can validate or kill by talking to the people who have it.
