The Milkshake Story & the Core Idea
Here is the one idea everything else builds on: people don't buy products — they "hire" them to make progress in their life. Instead of asking "who is our customer?" (age, gender, income), ask "what situation are they stuck in, and what progress are they trying to make?"
Everyday example — the drill and the hole
There's a famous line: "People don't want a quarter-inch drill — they want a quarter-inch hole." And really, they don't even want the hole. They want to hang a photo of their kids so their living room feels like home. The drill is just something they "hired" to make that progress. If someone invented a cleaner way to hang the photo, the drill gets "fired." JTBD keeps your eyes on the progress people are chasing — because that's what they're loyal to, not your product.
The famous milkshake study
A fast-food chain wanted to sell more milkshakes. They asked customers what flavors they'd like. Nothing worked. Then researchers simply watched when people bought milkshakes — and discovered half were sold before 8:30 AM, to commuters.
The commuters had a problem: a long, boring drive. Bananas were gone in a minute, donuts made fingers sticky on the wheel, bagels were too dry. A thick milkshake lasted 25 minutes, fit the cupholder, and kept them full until lunch.
The "job" was: keep me occupied, clean, and full during my morning drive.
