Jobs to Be Done: Why Customers Don't Buy Products

In the name of God, the Most Gracious, the Most Merciful

The Billion-Dollar Guessing Game

Imagine you're hiring someone for a critical role at your company. You have two approaches:

Approach A: Look at their age, gender, where they live, and how much money they make. Then guess if they'd be good at the job.

Approach B: Define exactly what job needs doing, then find the person whose skills match.

Approach A sounds absurd, right? Nobody hires employees based on demographics. But here's the thing — this is exactly how most companies think about their customers.

"Our target market is males 18-35 who earn $50K-$80K and live in urban areas." Sound familiar? That's Approach A applied to product development. And it explains why 75-85% of new products fail.

Not because the products are bad. Not because the teams are incompetent. But because they're asking the wrong question. They're asking "who is our customer?" when they should be asking "what job is our customer trying to get done?"

Correlation vs Causality: The History of Flight

To understand why this matters, let's go back to one of humanity's oldest dreams — flying.

For centuries, people watched birds and made what seemed like an obvious observation: birds have wings and feathers, and birds fly. So they concluded: wings + feathers = flight.

They strapped wings to their arms. They glued on feathers. They climbed to the top of cathedrals and jumped, flapping as hard as they could.

It never worked. People died trying.

And if they'd looked more carefully, they would have noticed the correlation wasn't even reliable. Ostriches have wings and feathers — and they can't fly. Bats have wings but no feathers — and they fly perfectly well. Flying squirrels have no wings or feathers at all — and they get by just fine.

The pattern was everywhere, and it was wrong everywhere too. Wings and feathers were correlated with flight — you could observe them together. But they didn't cause flight.

Then Daniel Bernoulli did something different. Instead of cataloging the attributes of things that fly, he studied the mechanism. He discovered the airfoil — a specific shape that creates lift by making air move faster over the top surface than the bottom. That was the causal mechanism.

Once engineers understood the actual cause, two incredible things happened:

1. They could build machines that flew — even without feathers, even without flapping wings. Because they understood the mechanism, not just the correlation.
2. When planes crashed, they could figure out why — "What was it about that specific situation that caused the mechanism to fail?" This led to if-then rules: if the angle of attack exceeds 15 degrees, then the wing stalls. Flight became predictable.

This is exactly where business stands today. Looking at customer demographics — age, gender, income, geography — is like looking at wings and feathers. These attributes are correlated with buying behavior, yes. But they don't cause anyone to buy anything.

"None of My Attributes Caused Me to Buy a Newspaper"

Clay Christensen — the Harvard professor who developed this theory — liked to make the point personal:

"I'm Clay Christensen. I'm 6 feet 8 inches tall, 62 years old, married for 38 years. I live in the suburbs of Boston. I drive a Honda minivan to work. I have a lot of attributes and characteristics. But none of those things caused me to go out and buy the New York Times today."

What caused the purchase was this: a job arose in his life. He needed to fill time while waiting at an airport. He looked around for something to hire for that job, and the New York Times got the interview.

The demographics — his age, height, income, education — are all correlated with buying the Times. But they didn't cause it. The job did.

The Milkshake Mystery

A major fast food chain wanted to sell more milkshakes. They did what any reasonable company would do — they brought in the quintessential milkshake customer and asked what they wanted.

"Should we make it chunkier? More chocolatey? Cheaper? Bigger?" Customers gave clear, thoughtful answers. The company implemented every suggestion. And... nothing happened. Sales didn't budge.

Then a researcher tried something different. He stood inside the restaurant for 18 hours. He recorded every milkshake sale — who bought it, when, what else they bought, whether they were alone or with someone.

What he found was startling: nearly half of all milkshakes were sold before 8:30 AM. The customers were almost always alone. They always drove off with the milkshake. And it was usually the only thing they bought.

The next morning, the researcher confronted these customers as they left with their milkshakes:

"Excuse me — what JOB were you trying to get done when you came here at 6:30 in the morning to hire this milkshake?"

They struggled to answer at first. So he asked a different way: "Think about the last time you were in this same situation — long boring commute ahead of you — but you DIDN'T hire a milkshake. What did you hire instead?"

Now they could answer. And the answers were fascinating:

• Bananas — "Gone too fast. Hungry again by 7:30."
• Donuts — "Crumbs on my clothes, fingers got gooey. Also hungry too fast."
• Bagels — "Dry and tasteless by themselves. Try spreading cream cheese while driving and the phone rings — now I've got three problems in two hands."
• Snickers bars — "Felt so guilty about eating candy for breakfast that I never hired one again."

The milkshake won the job interview every time. Here's why: it was thick and viscous, so it took 23 minutes to suck up through a thin straw. It kept one hand busy and the mind engaged during a boring commute. And it sat heavy in the stomach — not hungry until noon.

Once You Know the Job, Innovation Becomes Obvious

Now that you know the job, think about how you'd improve the milkshake for morning commuters:

• Make it MORE viscous — thicker means it takes longer to suck up. That's a feature, not a bug.
• Add tiny fruit chunks — not for health, but for unpredictability. "Oh, a strawberry chunk!" gives your mind a small surprise during a boring drive.
• Move the dispenser to the front of the counter — these customers are in a rush. Add a pre-paid swipe card so they can dash in, gas up, and go.

Notice how different these improvements are from "make it more chocolatey" or "lower the price" — the answers the focus group gave. When you know the job, the right innovations become obvious.

And here's another insight: how big is the milkshake market? If you measure it by milkshake sales (McDonald's + Burger King + Wendy's), it looks like one number. But if you measure by the job — "help me survive a boring commute" — the market is enormously bigger. Every banana, donut, bagel, and Snickers bar sold to a morning commuter is part of your actual market.

Is the market "mature" or "growing"? That question is meaningless until you know the job. Once you do, the answer becomes clear: there's massive growth potential.

What a Job to Be Done Actually Is

Let's be precise about what we mean by a "job to be done":

A job is a problem or opportunity someone is trying to solve or address in their life. When a job arises, people look around for something to hire to get it done.

Jobs to be done statements typically start with:

• "Help me..." — "Help me stay informed." "Help me survive my commute."
• "Help me avoid..." — "Help me avoid getting hungry before lunch."
• "I need to..." — "I need to furnish my apartment today."

Critically, jobs are NOT adjectives or adverbs. "Low cost" is not a job — it's an attribute of a solution. "Convenient" is not a job. "Fast" is not a job. These describe HOW something gets a job done, not WHAT job needs doing.

Here's the most important implication: if you define your business by your product, you live in an unpredictable, chaotic world where competitors come from nowhere and customers leave for no apparent reason. But if you define your business by the job, you get clarity, stability, and predictability.

Julius Caesar Had the Same Job as You

Here's a thought experiment that changes how you see business forever:

The job: "I need to get this information from here to there, with perfect certainty, as fast as possible."

That job has existed for over 2,000 years. But look at how the products hired to do it have changed:

• Julius Caesar — hired a horseman with a chariot
• Abraham Lincoln — hired the telegraph and the railroad
• FDR — hired the airplane
• Today — we hire Skype, email, DHL, WhatsApp

The job hasn't changed in 2,000 years. Every single product hired to do it has changed completely — many of them don't even exist anymore.

This is the most important strategic insight in the whole framework: if you frame your business around a product, you will get supplanted. Telegraph companies died. Pony Express riders lost their jobs. The railroad's dominance faded. But the job is still here.

If you frame your business around the job, you see every new technology as an opportunity, not a threat. You don't fight to protect your product — you race to find a better way to get the job done.

The Afternoon Milkshake — Same Product, Different Job

Remember the milkshake? There's a second half to the story that reveals something crucial.

Clay Christensen took his son Spencer to a fast food restaurant after school one day. Spencer looked at the menu and said, "Dad, can I have a milkshake?"

Clay — being a good father — said yes. And then watched as Spencer sat there... and sat there... taking forever to finish it. The milkshake was thick. It took ages through the thin straw. Finally Clay said, "Spencer, we don't have time for this" — and threw away the half-consumed milkshake.

Wait. The same product that was perfect for the morning commute job was terrible for the afternoon job. Why?

Because the job was completely different:

• Morning job: "Help me survive a boring commute and stay full until lunch" — thick, slow, filling
• Afternoon job: "I want to feel like a good dad by giving my son a treat" — needs to be thinner, smaller, faster to finish

Functional, Emotional, and Social Jobs

Every job to be done has two dimensions, and understanding both is critical:

Functional dimension: The practical problem being solved. "Help me be clean-shaven." "Help me get from home to work."

Emotional and social dimension: How using the product makes you feel, and how it makes others see you. "Help me feel like I belong to an exclusive group." "Help me show the world I've made it."

Most products serve BOTH dimensions — but usually one dominates:

A Merry-Go-Round and a Father's Insight

In the early 1950s, Walt Disney took his two young daughters to a small amusement park in Los Angeles. While his kids rode the merry-go-round, Walt sat on a bench to the side, watching.

And in that moment, he had an insight that would create one of the most successful businesses in history.

He realized: "We just need occasionally to go away from where we live and immerse ourselves in a fantasy together — an experience we would remember for the rest of our lives."

He looked around Southern California — the beaches, the parks, the mountains. Nothing was designed around that job. There were amusement parks with rides. There were beaches with sand. But nothing that said: "Come here, leave reality behind, and step into a story with your family."

The job: "Help me escape reality into a storytelling experience with my family."

How Disney Integrated Around the Job

What Disney built was extraordinary — not because of the technology or the rides, but because of the integration around the job:

• Characters — created beloved characters that people grew up with
• Stories — built emotional narratives around those characters
• Films — brought the stories to life so millions could fall in love with them
• Theme Park (1955) — created a physical place where you could play out the fantasy

But the genius was in the details of the experience:

• Five themed lands with a full-size castle at the center
• Characters alive — walking around, greeting children, signing autographs
• Walls around the entire park — you can't see the outside from inside, and the outside can't see in. You're not in Anaheim anymore — you're in a fantasy world.
• Main Street USA — walking down Main Street signals that you're leaving reality behind and entering the story

The result: nobody could compete with Disney for four decades. Not because of secrets. Not because of proprietary technology. Not because of patents. But because of integration around the job. You can copy a ride. You can't copy an integrated system designed from the ground up to nail a specific job.

And here's the remarkable thing — that job hasn't changed. As Clay put it: "I'm 62 years old, unfortunately. But as I was growing up, our family had that job to be done. As I was raising our children, we had the same job to be done. And now our children have children, and they have the same job to be done." Julius Caesar probably had that job. Abraham Lincoln had it too.

Because the job is so stable over time, it becomes a kind of North Star for innovation. Anything that helps families escape into a storytelling experience together — invest in it. Anything that doesn't serve that job — cut it. Without a clear job to focus on, innovation feels unpredictable. With one, every decision has a compass.

The $1 Billion Mistake: California Adventure

In 1998, Disney's management made a decision that perfectly illustrates what happens when you abandon jobs-to-be-done thinking.

They wanted to turn Southern California into a multi-day destination. More days = more hotel revenue. So they built a second park right next door to Disneyland: Disney California Adventure.

But instead of building another place designed around the family fantasy job, they went after a different demographic: teenagers and thrill-seekers. They built California Screamin' (a roller coaster), Hollywood Tower of Terror, and marketed it as "Disneyland's hipper, edgier younger sibling."

The result was devastating:

• Projected attendance: 7 million visitors. Actual: never broke 6 million.
• An 18-year-old visitor said: "Disneyland is a magical place, but California Adventure is just a theme park you can get anywhere."
• A Disney executive admitted: "Guests have told us that when they stand in California Adventure, they don't have an emotional connection to it."

They spent $1 billion building a park that failed — not because the rides were bad, but because they abandoned the job. They tried to serve a different demographic (thrill-seeking teenagers) instead of doubling down on the job that made Disney unbeatable (family fantasy escape).

Bob Iger's $1.1 Billion Fix

In 2007, CEO Bob Iger made a bold decision. He called the park a "brand withdrawal" and committed $1.1 billion over five years to fix it.

The fix? Return to the job.

• Cars Land — step into the movie. Walk through Radiator Springs. See Lightning McQueen.
• Toy Story Land — become a toy in Andy's backyard
• Little Mermaid interactions — Ariel's undersea adventure

This wasn't copying an old strategy. The job hadn't changed. "Help me escape reality into a storytelling experience with my family" was the same job Walt identified on that bench in the 1950s. Iger just found better ways to get it done — with new characters and new stories.

The result? Success. Because when you return to the job, the customers return too.

The Architecture That Makes Companies Unbeatable

You've now seen the Disney integration stack in action. That stack is actually a universal framework — the Jobs to Be Done Pyramid — that explains why some companies become virtually impossible to compete with.

The pyramid has four layers, built from the bottom up:

IKEA — 50 Years, Zero Competitors

Clay Christensen's son Michael got accepted to a PhD program at Stanford. He called his dad, excited: "I found the apartment. I need to furnish it — tomorrow."

When you hear that job — "I need to furnish my home today" — what company pops into your head instantly?

IKEA.

Think about what IKEA integrated around that job:

• Intuitive store layout — follow the path, room by room. You don't need a design degree to figure out what goes together.
• Everything in flat-pack boxes — fits in your car. No delivery wait.
• Take it home TODAY — not in 6-8 weeks. Today. The warehouse is right there in the store.
• Room displays — see exactly how it looks in a real room before buying
• Swedish meatball restaurant — because furnishing a home takes hours, and you'll get hungry
• Children's play area — because parents with kids need time to choose, and kids get bored

IKEA has been rolling out worldwide for 50 years. No competitors. Not because of patents or technology or secrets — IKEA's founder became the 3rd richest person in the world. The reason nobody can compete is integration around the job.

Competitors can copy any individual product. Anyone can make cheap furniture. But you can't copy the way IKEA is organized — the store layout + flat-pack + take-home-today + room displays + restaurant + play area. All of these are experiences that nail the job. Copying ONE piece doesn't work. You need all of them, working together.

5 Ways to Find Jobs to Be Done

The million-dollar question: how do you actually find jobs to be done? Here are five methods, drawn from the most successful innovators in history:

Method 5 deserves special attention. Compensating behaviors are when people cobble together awkward workarounds because nothing good exists to hire for their job.

Here's a classic example: before OpenTable existed, coordinating dinner with four friends meant calling restaurants, getting availability, calling friends back, someone couldn't make Tuesday, calling the restaurant again, trying Thursday, calling friends again, one person doesn't answer, leaving a voicemail, waiting, calling back...

All that back-and-forth was a compensating behavior — a painful workaround for the job "help me coordinate a group dinner easily." OpenTable saw those workarounds and built a product that got the job done. Whenever you see people doing ridiculous workarounds, there's a job to be done hiding in plain sight.

The Earache That Changed Healthcare

A busy working mom in Minneapolis wakes up to her youngest daughter crying with an earache. Mom takes out her otoscope (she's seen this before), looks in the ear, and sees it's pink.

She knows it's an earache. She's seen several. So she calls the doctor:

"Trust me — I've seen earaches. Can you just call in amoxicillin to the pharmacy?"

Doctor: "I have to see her."

"When can we come in?"

"Wednesday."

It's Monday.

"She's in pain!"

"Come in at 2 PM. I'll try to work you in."

So this mom leaves work in the middle of the day, picks up her daughter from school, drives to the doctor's office, and waits two hours.

Finally, the doctor calls them in. He looks in the daughter's ear for fifteen seconds and says:

"She has an earache."

The mom already knew that. The entire system — the appointment, the wait, the two-hour delay — existed not to diagnose the problem (the mom already knew the answer) but to fulfill a process designed around the doctor's needs, not the patient's.

Designing Around the Job

Minute Clinic was built specifically around this job, with two brilliant design principles:

1. Only diseases with YES/NO answers. Earache? Yes/No. Strep throat? Yes/No. Pink eye? Yes/No. If the answer is "maybe" — go see a doctor. No ambiguity. No gray areas.
2. Response every 5 minutes. You walk in. Within 5 minutes, a nurse practitioner sees you. No appointment. No unpredictable waiting. Every 5 minutes, predictable progress.

Nurse practitioners — not doctors — staff these clinics. They can do almost everything a doctor does for simple, clear-cut conditions. And they cost a fraction of a doctor's time.

Now look at Minute Clinic through the JTBD Pyramid:

• Job: Help me quickly and conveniently get healthcare without seeing a doctor
• Experience: No waiting, no appointment, no ambiguity. Walk in, get diagnosed, get a prescription — all in minutes.
• Integration: Located inside CVS and supermarkets — go where people already go. Pharmacy is 20 steps away (no separate trip to fill the prescription).
• Purpose Brand: "Minute Clinic" — it's a clinic, in a minute. The name is the job.

And this brings us full circle to where we started. One of the most important dimensions of the Jobs to Be Done concept is this: what causes you to buy a product or use a service is not that you belong to a particular demographic. What causes people to walk into a Minute Clinic is not that they're in a demographic with a propensity to need healthcare. They go when they have a job to do — an earache at 9pm, a sore throat before a flight, a child with a fever on a Sunday.

Demographics don't cause purchases. Jobs do. And once you see that, you can't unsee it.

What To Do Monday
