# Competing Against Luck
**Author**: Clayton M. Christensen with Taddy Hall, Karen Dillon & David S. Duncan | **Pages**: ~256 | **Chapters**: 10 (+ Introduction) | **Generated**: 2026-06-08

## How to Use This Skill

- **Without arguments** — load core frameworks for reference
- **With a topic** — ask about `forces of progress`, `nonconsumption`, `job spec`, `the three fallacies`; I find and read the relevant chapter
- **With chapter** — ask for `ch05`; I load that specific chapter
- **Browse** — ask "what chapters do you have?" to see the full index

When you ask about a topic not in Core Frameworks below, I read the relevant chapter file before answering.

## Core Frameworks & Mental Models

**The central question** — *"What job did you hire that product to do?"* Customers don't buy products; they **hire** them to make progress, and **fire** them when something does the job better.

**The Job to Be Done (the definition)** — *A job is the progress that a person is trying to make in a particular circumstance.* Three load-bearing words:
- **Progress** — movement toward a goal/aspiration. A job is never just a function; it's a verb-driven struggle, not a product category or a customer attribute.
- **Circumstance** — the job is defined by the *situation*, not by customer demographics, product attributes, technology, or trends. "I'm a 40-year-old male" doesn't cause a purchase; "I have a long, boring morning commute and one free hand" does. **The circumstance is the fundamental unit of innovation work** — not the customer.
- **Functional + Social + Emotional dimensions** — every job has all three; the social and emotional are often heavier than the functional. Miss them and you miss the job.

**Jobs are stable; solutions churn.** The job ("get me from A to B reliably") barely changes over decades; the products hired to do it (horse → car → Uber) change constantly. Innovate against the job, not the current solution.

**The Milk Shake Dilemma** — When you study the *product* (improve the shake), you optimize the wrong thing. When you study the *job* (the morning shake is hired to make a boring commute survivable with one hand; the afternoon shake is a different job — a dad placating a kid), you see what to build and what you really compete with. Same product, two different jobs.

**Competing against nonconsumption / "competing with nothing"** — your real competition is often not a rival product but the customer doing nothing, or a clumsy workaround. The biggest growth lives where people are currently *not* solving the job at all.

**Causality, not correlation** — Big Data shows *what* correlates; Jobs Theory supplies the *causal mechanism* of why people buy. Data describes; the job explains and predicts. Most data measures attributes of customers and products — neither of which causes a purchase.

**Big Hire / Little Hire** — the **Big Hire** is the purchase (money changes hands); the **Little Hire** is every time the customer actually *uses* the product to get the job done. A product can be Big-Hired and never Little-Hired (bought, never used) — that's a job not actually being done.

**The Forces of Progress** (the switch happens only when push + pull > habit + anxiety):
- **Push** of the situation — the frustration/struggle with the current state.
- **Pull** of the new solution — the attraction of the new idea.
- *(opposing)* **Habits of the present** — inertia; "it's good enough."
- *(opposing)* **Anxiety of the new** — anxiety of choosing + anxiety of using.
To win a switch you must amplify push+pull **and** actively dismantle habit and anxiety — most innovators ignore the two opposing forces entirely.

**The Job Spec → the Résumé** — write the job as a spec: the functional/social/emotional dimensions, the trade-offs the customer will make, the obstacles to remove, the competing set ("the job's résumé of candidates"). Then design the product as a *résumé* that perfectly matches the spec — including the **experiences** of purchase and use that the job requires.

**Experiences, not features, command premium prices and loyalty.** Competitors can copy features; the right set of experiences wrapped around the job is what's hard to copy and what earns a **purpose brand** — a brand the customer mentally equates with the job ("milk for my Oreos," "I'll just Uber there"). A purpose brand is the highest-leverage asset in innovation.

**Integrate around the job, not the function.** *Processes* — how you integrate to get the customer's job done — are the durable competitive advantage, because they're invisible and hard to copy (Mayo Clinic, Amazon). Org charts are built around functions and products; the job cuts across them.

**The Three Fallacies of Innovation Data** — why good companies lose sight of the job:
1. **Fallacy of Active vs. Passive Data** — once a product ships, "operations" data (active, abundant, easy) crowds out the rich, passive, context-laden data of the original job. The map replaces the territory.
2. **Fallacy of Surface Growth** — chasing growth by selling more *products* to existing customers (line extensions, adjacencies) pulls focus off the core job and dissolves the company's purpose-brand clarity.
3. **Fallacy of Conforming Data** — managers unconsciously bend data to fit the model they already believe; data has no voice of its own.

**The Jobs-Focused Organization** — make the job, not the function, the organizing principle. Like **commander's intent**, a clearly understood job lets people at every level make the right call without escalating. Benefits: distributed decision-making, resource optimization toward the job, inspiration, and *better measurement* (you measure progress on the customer's job, not internal proxies).

**"People don't want a quarter-inch drill; they want a quarter-inch hole."** (Levitt) — and even that is only a proxy for the deeper progress (a shelf up, a happy spouse, a tidy home). Keep asking what progress the hole is for.

## Scope & Limits

This skill covers the book's content only — Jobs Theory as a lens for innovation, customer research, and organizing the firm. It is not a substitute for primary customer interviews; the book's whole point is that *you must do the field work*. For hands-on application, combine with project-specific research and pair with related skills (e.g. `fitzpatrick-mom-test` for the interview craft, `dunford-positioning` for naming the competitive frame).
