Clay Christensen: The Jobs to be Done Theory (the milkshake example)

Clayton Christensen (HubSpot Marketing) · YouTube Free Beginner

This is the canonical newcomer walkthrough: Christensen shows a team improving a milkshake on every obvious dimension and moving nothing, because they had the job wrong. It makes the good-versus-bad framing concrete in a few minutes, which is exactly the trap founders fall into when they optimize a feature instead of the job. Start here if the concept still feels abstract.

  • Improving a product on the wrong dimensions is what a bad job statement looks like in practice.
  • The same product can be hired for very different jobs (the morning commute versus the afternoon treat), so the situation defines the job.
  • Watch what people hire and fire, not just what they say they want, to name the job correctly.

  2. How specific should my ideal customer be for a consumer app versus a B2B tool?
  3. What are the most common ways founders get JTBD wrong in practice?
  4. How do I do competitive research for a brand-new category where there are no direct competitors yet?
