Approach

Jobs to be done

Understanding customers by the progress they are trying to make in a specific situation, the “job” they hire a product for, not by their demographics.

Origin
Its origin is debated; popularized by Christensen and Raynor (2003) and formulated as a theory by Christensen, Hall, Dillon and Duncan (2016)

What it’s for

It explains why someone buys a product and what it really competes with, something demographics don’t tell you.

Principles

  • The situation matters

    The same product is hired for different jobs depending on the moment.

  • More than function

    The job also has an emotional and a social side.

  • The real competition

    Anything that could do the same job, even if it looks nothing alike.

How it’s done

  1. Look at the situation. When, where and with whom the product is chosen.

  2. Find the job. What progress is sought and what alternatives are used.

  3. Design for that job. Improve what matters in that situation.

Applications in design

  • When to use it

    To understand why people choose, switch or abandon a product, especially against very different alternatives.

  • Avoid

    Confusing the job with a product feature.

  • Don’t fall for it

    Ask about the last time the person chose a solution, and don’t stop at the functional side: also ask how they felt and how they wanted to be seen.
