How should a market be defined?
It’s worth remembering that people buy products and services to get a “job” done. A job is defined as a task people are trying to accomplish, a goal or objective they are trying to achieve, a problem they are trying to resolve, something they are trying to avoid, or anything else they are trying to accomplish. More about Jobs-to-be-Done Theory here.When looking at a market through the Jobs-to-be-Done lens, a market is best defined as: a group of people and the job they are trying to get done.
For example, parents (a group of people) who are trying to “pass on life lessons to children” (a job-to-be-done) constitute a market. As do surgeons (a group of people) who are trying to “repair a torn rotator cuff” (a job-to-be-done), or clinicians (a group of people) who are trying to “diagnose the cause of a patient’s sleep disorder” (a job-to-be-done).
When defining markets with a jobs-to-be-done lens, thousands of unique markets exist. They are stable over time, focus on what people are trying to accomplish rather than solutions, offer a focal point for analysis, and form a foundation for deeply understanding customer needs. Learn about needs through this lens here.
Because the market is defined using “Jobs-to-be-Done” before engaging in the first step of the Lean Startup methodology, the defined market will not change as customer discovery and validation of that market unfolds. This cuts back on the number of iterations and pivots.
Big idea – Even New and Disruptive Markets can all be viewed as “Jobs-to-be-Done”
How does “Jobs-to-be-Done” work in new and disruptive markets? For example, people often talk about the cryptocurrency market as a new market, but is it really? It depends how you define “market.”If you choose to define a market around a new product or a new technology, then, by definition, the “cryptocurrency market” would be considered new. But if you define the same market through a jobs-to-be-done lens, the story is very different, as consumers (a group of people) have for centuries been trying to intermediate the storage and exchange of value over time (the job-to-be-done).
When looking through a jobs-to-be-done lens, cryptocurrency is simply a new offering in a pre-existing market. Similarly, Uber, Netflix, electronic evidence discovery, cloud computing, smartphones, online learning, Airbnb, Spotify, Google Maps and many other products considered disruptions are in fact new offerings in pre-existing markets.
Why does this matter? When conducting needs discovery, potential customers struggle to articulate needs for a product that does not yet exist. But when you ask them about their job-to-be-done, customers can state with precision their needs associated with getting the job done better, making needs discovery faster and more effective.

What other products do people use in conjunction with the product?
What “job” does each of the other products get done?To get a feel for the entire job your customer is trying to get done, ask them what other products they use immediately before, while, and immediately after using your product/service.
For example, when tradespeople use a circular saw to “cut wood,” what other products are they using in conjunction with a circular saw? Perhaps they are also using a T-square, a measuring tape, sandpaper, and (or) a pencil.
List the products they use in conjunction with the one you have in mind.
Putting all the pieces together helps reveal the customer’s ultimate job-to-be-done at the right level of abstraction. Assume your product is getting part of a job done. Assume people are using these other products to complete the entire job-to-be-done.
You want to define your customer’s job-to-be-done in a way that includes your product’s function (job) and rationalizes why customers are using all these other products as they cobble together a complete solution. The Bosch team, for example, determined that tradespeople are using a circular saw along with other products so they can “cut wood in a straight line” (the abstracted job statement).
Defining the market at this level of abstraction allows you to evolve your product over time to help customers get more, and eventually all, of their job done—preferably before competitors do. It offers the innovator a built-in path and vision for growth—tied directly to what customers are trying to accomplish.
