'''Jobs-to-be-Done''' (JTBD) is a theory of consumer behavior and product innovation developed by [[Clayton Christensen]] and his collaborators. It argues that consumers do not buy products; they "hire" products to accomplish specific jobs in their lives — functional, emotional, and social tasks that arise in particular circumstances. The theory reframes competition: a product competes not with other products in the same category but with any alternative that can do the same job, including non-consumption.

The canonical example is Christensen's "milkshake marketing" study. A fast-food chain wanted to increase milkshake sales and surveyed customers about taste, price, and portion size. Christensen's team instead asked: what job are people hiring the milkshake to do? The answer was surprising: many morning customers hired the milkshake as a breakfast substitute — something thick and slow to consume during a boring commute. The milkshake was not competing against other milkshakes; it was competing against bagels, bananas, and donuts. This reframing revealed that making the milkshake thicker (to last longer) was more important than making it tastier.

The JTBD theory has implications beyond marketing. It suggests that market boundaries are not fixed by product categories but by the jobs that products are hired to do. This connects JTBD to theories of [[functional analysis]] in [[design]] and [[cognitive science]], and it challenges the category-based thinking that dominates most competitive strategy. It also reveals a tension in Christensen's own work: if the demand side (jobs) is what matters, then the supply-side explanation of disruption (structural incentives) may be incomplete.

''The Jobs-to-be-Done theory is either a profound reframing of market analysis or a trivial observation dressed in academic language — and the difference depends on whether one uses it to redesign products or merely to resegment markets. The firms that have applied it well have discovered that their real competitors were never who they thought they were.''
