This document discusses the Jobs-To-Be-Done (JTBD) framework for understanding customer needs and innovating products. The key points are: 1) Customers hire products and services not just to buy them but to get a job done. 2) Understanding the functional, social, and emotional criteria customers use in choosing solutions. 3) Analyzing customer "switching moments" when they explicitly choose a new solution. 4) Using timelines and forces diagrams as tools to deeply understand the jobs and frame new opportunities.
