Methods for the Business Model Generation: how #bmgen and #custdev fit perfectly

Blog: Business Model Alchimist

The Business Model Generation is about people who strive to defy outmoded business models. They are visionaries, game changers, and challengers who want to design tomorrow’s enterprises. To succeed on this journey they will require new tools, such as the Business Model Canvas and Steve Blank’s Customer Development. In this post I outline how they fit together.

This post comes mainly as a reaction to the various attempts by others to adapt and merge the Business Model Canvas with Customer Development for the entrepreneurial context. While it’s great and fascinating to see how people are tinkering with Steve’s and our method to adapt them for their start-ups, I am also worried that they lead young companies down the wrong path.
Steve and I have both already written about how our methods fit together here (Steve) and here (me). However, this time I took some time to sketch out a more detailed start-up process that merges the concepts and tools from Steve’s bestselling The Four Steps to the Epiphany and our globally bestselling Business Model Generation – A Handbook for Visionaries, Game Changers, and Challengers. Additional concepts and tools, such as Eric Ries’ Lean Start-up, may be added subsequently.

I will illustrate this process through the fictional story of Dave Sanburn, a former finance type based in Dallas, who decided to launch his own start-up. His entrepreneurial story all started with an unsatisfied customer need that gave him the idea for his start-up.

1) The Business Idea and Initial Stress Tests

Dave likes wearing tailor-made shirts, but sees shopping as a chore. He used to buy these kind of shirts during his business trips to London, but was never really satisfied, neither by the experience nor the price. When Dave realized that it was not so easy to conveniently find and buy tailor-mode shirts in Dallas he wondered if this could be a business idea worth pursuing.

Ideas for a business can have various origins. Sources could be:

Let’s get back to Dave and help him run a first rough stress test of his business idea. Dave should look at four areas: customers, key trends (e.g. technology), competitors, and the macro environment. (These for areas are a simplification of the Business Model Environment outlined in Business Model Generation).

Dave should investigate a series of questions related to each of the four areas:

In the graphic below I added four of the concepts from Steve’s The Four Steps to the Epiphany, which I think can be of tremendous help at this stage (additions in red).

Regarding customers (right-hand side), Dave should start sketching out some first rough customer hypotheses and problem hypotheses. Steve’s book contains excellent worksheets with questions to develop the hypotheses. Regarding competition (left-hand side), Dave should add a first rough take on the market type hypothesis and competitive hypothesis.

Stress-testing the business idea is part desk-research (thank you Google) and part “getting out of the building”, to use Steve Blank’s terms. The goal of this phase is to figure out if a business idea is worth pursuing.

2) Business Model Prototyping – Generating Alternatives

After some initial research Dave decides to continue investigating his business idea. The question is: how can he offer tailor-made shirts in a viable way and how can he turn this into multi-million dollar business?

At this point many entrepreneurs fully focus on the product or service they are planning to offer. Big mistake. It’s far more illuminating to sketch out and think through several alternative business models for a product, service, or technology.

#bmgen and #custdev

The same product, service, or technology may fail with one business model, but succeed with another. For example, few people know that Nespresso – today a 2+ billion USD business owned by Nestlé – almost failed in the late 80s because of an unsuccessful business model. With exactly the same product and technology (Nespresso machines and pods), but a very different business model, Nespresso started its global conquest of the espresso market.

I call this phase business model prototyping. It’s the one that business people and entrepreneurs struggle most with. Rather than sketching out 4-6 potential business model alternatives in 60 minutes, most people feel more comfortable merely discussing ideas or one single business model. Big mistake. It’s more valuable to have several business model alternatives on the table so you can discuss their strengths and weaknesses.

To compare the different potential business models you particularly want to play around with ballpark figures for each alternative. You can either do this with a spreadsheet or even more conveniently with our upcoming iPad app (don’t ask for the release date ;-).

3) Selecting a Business Model: Plan A

After going through several alternatives and comparing them with a set of criteria Dave has selected the one he thinks looks most promising. It’s illustrated in the next three images.

This first Business Model Canvas below illustrates the basic model of offering tailor-made shirts that are manufactured in China to white-collar office workers in big US cities. The hundred million-dollar question is of course how to reach them, i.e. through which channels?

This is where Dave’s business model becomes special. He plans to operate no stores and no sales force. His intention is to generate sales through independent “style advisers” who will earn commissions of up to 25 percent on clothing they sell.

MeShirt Business Model

The second Canvas illustrates the value proposition that shall attract the “style advisers” who will essentially be recruited by other advisers. Like in most direct-sales companies, advisers will get a cut of the sales made by reps they recruit.

MeShirt Business Model

The last Canvas shows how Dave’s company is different from most other shirt retailers. For example, he operates no stores, no sales force, and only manufactures shirts that have already been sold.

4) Testing the Business Model – Customer Development

As attractive as this first business model might look, it’s nothing else than a set of guesses. Nobody knows if it’s really going to work? This is where the real value of Steve Blank’s Customer Development kicks in. Each post-it note in the Canvas should be turned into a hypothesis and then tested. In Steve’s 4-step methodology this is the first phase called Customer Discovery.

Visually this can be represented with three layers. A first (Canvas) layer represents the business model. This is what we just outlined above with Dave’s example of a tailor-mode shirt maker. The second (Canvas) layer outlines the underlying hypothesis for each post-it note. The third (Canvas) layer turns each hypothesis into a test, so that it can be verified and measured.

3 Layers: Business Model, Hypotheses, Tests

Let’s briefly go through these three layers with a simple example that Dave could put in practice:

The challenge for Dave is to develop the three layers for each business model building block and post-it note in the Canvas ranging from customers, over value proposition, all the way to resources, and cost structure.

When Dave tests the business model with customers he is likely to modify it in an iterative fashion every time he learns more from customers. Once he thinks he’s got it right, he can continue with the remaining 3 steps of Customer Development, notably Customer Validation, Customer Creation, and Company Building.
