What is Jobs to Be Done?
Jobs to Be Done (JTBD) is a product-development framework developed by Clayton Christensen that reframes customer needs around the underlying “job” a customer is trying to accomplish, not the demographic profile of the customer. Customers don’t buy a quarter-inch drill bit because they want a drill bit; they buy it because they need a quarter-inch hole. Understanding the job-to-be-done shifts product strategy from feature lists to outcome design.
The milkshake example
Christensen’s classic case study: a fast-food chain wanted to sell more milkshakes. Demographic segmentation gave no useful direction. JTBD analysis revealed that morning milkshake buyers were commuters using the shake as a single-handed, mess-free breakfast that lasted the drive to work. The job: “make my commute less boring without spilling coffee on my shirt.” The redesign followed: thicker shakes, faster drive-thru lanes, larger cups.
How to do JTBD research
Three steps. (1) Customer interviews — ask “the last time you bought X, what were you actually trying to do?” not “do you want feature Y?” (2) Job mapping — break the underlying outcome into stages (define, locate, prepare, confirm, execute, monitor, modify, conclude). (3) Outcome statements — quantify what success on each stage means to the customer. Tony Ulwick’s “outcome-driven innovation” extends Christensen’s framework with this rigor.
JTBD vs. personas
Personas describe who the customer is (demographics, behaviour patterns, channel preferences). JTBD describes what the customer is trying to do (functional outcome, emotional state, social signal). JTBD scales better across segments: the same underlying job can be performed by very different demographic groups. Persona-only product strategy misses customers outside the persona; JTBD-grounded strategy captures everyone trying to accomplish the same job.
Functional, emotional, and social jobs
Most jobs have three dimensions. (1) Functional — the practical outcome (“transport me from A to B”). (2) Emotional — the feeling the customer wants (“feel confident, in control”). (3) Social — the signal the customer wants to send (“be seen as someone who values quality”). Tesla’s success on all three dimensions vs. legacy luxury sedans illustrates how a job-completion bundle wins.
Türkiye context
For Türkiye-based founders, JTBD is especially useful in markets where Western personas don’t map cleanly. A Türk small-business owner buying accounting software isn’t the same “SMB persona” as their EU counterpart — different regulatory job (KDV reporting), different emotional state (tax-audit anxiety), different social signal (compliance demonstrates business legitimacy). Designing for the actual job, not the imported persona, produces dramatically better Turkish product-market fit.
