How: Formulate the concept of your product by defining your target customer, their problems, and how you will solve those problems. Using a framework such as the Business Model Canvas can aid a nuanced result. Most of what you write down will be assumptions, so consider which are the riskiest and how you will test them.

Why: The simple act of writing forces you to consider things you may have previously glossed over. By being explicit about the problems your product solves and the assumptions you make, you can validate whether customers also see these as problems and whether they are seen as worth solving.

Before the experiment

The first thing to do when planning any kind of test or experiment, is to figure out what you want to test. To make critical assumptions explicit, fill out an experiment sheet as you prepare your test. We created a sample sheet for you to get started. Download the Experiment Sheet.

Force yourself to consider everything

The simple act of going through a predefined template and writing down your concept, can help force you to consider things you may have previously skipped. Answering a few key questions that you can go out and test subsequently, can help you get a great start.

Tools like the Business Model Canvas, the Lean Canvas, or the Opportunity Canvas can act as great starting points to guide your thinking.

Ultimately, aim for writing down basic assumptions that you can readily go out and test:

  • Who is your target customer? ‘Everyone’ is not your target customer. Be specific about what kind of businesses or people you are targeting? What about the market size of each segment? If the buyer works in a company, what is his or her title?
  • What problems are you solving? Your starting point should be in the problem you are solving - not the solution you have intended to solve the problem. Be explicit about the problem your product solves. Once you have written it down, you can start validating whether your potential customers also see the problems you identified as problems of their own – and whether they see those problems as worth solving.
  • How does your product solve these problems? You need to define the problem you’re solving before moving to the product. How will solving the problems of your potential customers make their life better? Will it make them more money? Feel better about themselves? Be more efficient?
  • What are the key features of your product? Do your features map to actual and specific customer problems (jobs, pains, and gains)?

After the experiment

To make sure you move forward, it is a good idea to systematically record your the insights you learned and what actions or decisions follow. We created a sample Learning Sheet, that will help you capture insights in the process of turning your product ideas successful. Download the Learning Sheet.

  • Lean Canvas

    Keep our ideas succinct and robust by spending 20 minutes on filling out this canvas.

  • Opportunity Canvas

    Can help facilitate a discussion around a new feature or capability. It assumes you've got a product already, so you won’t need to reconsider the operational or revenue model, which is what the other canvases ask you to deal with.
