When to Use the Lean Canvas Instead
The Lean Canvas is a one-page variant built for ideas nobody has paid for yet. Use it before you have customers, and move to the Business Model Canvas once you are running a business you need to explain and improve.
Ash Maurya adapted the canvas in 2010 for start-ups whose biggest risk is that nobody wants the product. He swapped out four blocks: Key Partnerships, Key Activities, Key Resources and Customer Relationships. In their place are Problem, Solution, Key Metrics and Unfair Advantage.
The swap moves the page from how you deliver to what you have not proven. A founder with a meal-planning app idea and no users learns more from writing the top three problems her buyers have and the one number that shows the app is working than from listing suppliers she does not have yet.
You have an idea and no paying customers yet
The biggest unknown is whether the problem is real
You need to pick the one number to watch first
Customers already pay and you are improving the model
Partners, resources and costs are where the risk is
You are comparing your model with a competitor's
Both canvases hold guesses until a customer, a price test or a cost check turns them into facts.
A bakery has sold to 300 regular customers for three years and wants to add wholesale deliveries to cafés. Which canvas suits the decision better?
The Business Model Canvas, because the risk sits in partners, resources and costs
The Lean Canvas, because wholesale is a new idea for the bakery
The Lean Canvas, because it is quicker to fill in
Neither, because a canvas only works before launch
The bakery's problem and demand are already proven. The open questions are about delivery partners, van and staff costs, and whether wholesale prices cover them, which are the left-side blocks the Lean Canvas drops. The Business Model Canvas keeps them on the page.
