Idea Napkin
Quick idea sketch on a napkin - the core elements of a business idea.
PURPOSE
In early innovation phases, teams need a quick format to capture the core elements of a business idea before details are worked out. The Idea Napkin makes it possible to reduce a business idea to its essentials in just a few minutes and make it communicable. It prevents promising ideas from getting lost and creates a basis for further development.
HOW TO USE
The core elements of the business idea are sketched on a single-page template, similar to how you would jot down an idea on a napkin. Typical fields include problem, solution, target customer, value proposition, and revenue model. The Idea Napkin is intentionally filled out quickly and informally to avoid interrupting the flow of idea generation. It serves as a starting point for deeper analysis with tools like the Business Model Canvas.
WHAT IT IS
The Idea Napkin is a compact canvas tool for quickly capturing the core elements of a business idea on a single page. It typically contains fields for the problem statement, the solution idea, the target customers, the value proposition, and a rough revenue model. The name references the tradition of sketching breakthrough ideas on a napkin.
EXAMPLE
Example: Over lunch, a colleague tells you about his idea for an app that connects tradespeople and material suppliers in real time. On the Idea Napkin, you sketch out the core elements in five minutes: target audience (small trade businesses), problem (long wait times for materials), solution (real-time marketplace), and revenue model (commission per order).
