Competing Against Luck: The Story of Innovation and Customer Choice

Customers hire products to make progress in specific life circumstances — not because of demographics or features
Every job has three dimensions: functional, social, and emotional — social/emotional often outweigh functional
Innovation fails from the correlation-causation gap: massive data about who bought what, zero insight into why
Competitive advantage lives in the experience, not the product — design the full hiring-to-using journey
A well-articulated job serves as commander's intent for the entire organization

Situation	Do This	Avoid This
Discovering customer needs	Use the five job-hunting methods: own life, nonconsumption, workarounds, negative jobs, unusual uses	Surveys, focus groups, feature request lists
Designing a new product	Build a job spec across all three dimensions, then design the full experience	Optimizing features without understanding the job
Entering a new market	Look for nonconsumption — people hiring nothing	Stealing share from incumbents on their terms
Customers buy but don't use	Track Little Hires (usage), not just Big Hires (purchases)	Celebrating sales numbers without retention data
Product adoption is slow	Map all Four Forces — reduce anxiety and break habits, not just increase pull	Adding more features to increase attractiveness
Brand losing differentiation	Reconnect to the original job; check for organizational drift	Broadening the brand to chase adjacent markets
Internal teams can't prioritize	Articulate the job as commander's intent — it tells you what to do AND what not to do	Mission statements too vague to guide decisions
