Reference table
Two schools of Jobs to Be Done
Jobs as progress versus jobs as activities

Jobs to Be Done has two main interpretations that people often mix up. Christensen and Moesta treat a job as progress in a circumstance and study it with switch interviews. Ulwick's Outcome-Driven Innovation treats it as a process with measurable outcomes and adds large surveys. This table helps you choose which school fits the question you are asking.
