This document discusses the "jobs-to-be-done" (JTBD) methodology for understanding customer behavior and needs. The JTBD approach focuses on the specific problems customers hire products and services to solve, rather than general needs statements. Customers want products and services to help them accomplish tasks and achieve goals. Understanding the specific jobs helps identify opportunities for new or improved offerings. The document provides examples of how analyzing jobs was useful for product development and discusses reasons why products may fail if they do not adequately address the job.
