Building the first lean business plan
Create a useful one-page business model, connect its assumptions, and revise or pivot as evidence arrives.
A plan is a system of assumptions
A lean plan connects customer problems, segments, value, solution, channels, revenue, costs, metrics, and advantage. Its value comes from seeing whether those parts support one another.
Write concise current beliefs rather than aspirational prose. Mark the assumptions with the highest uncertainty and greatest consequence.
Keep in mind
- Keep the first version on one page.
- Link each claim to evidence or label it an assumption.
- Use milestones to resolve risk, not merely ship features.
Revise deliberately
A revision improves the current model without changing its fundamental direction. Record what changed, why it changed, and which evidence influenced the decision.
Keeping a short decision trail prevents the team from cycling through old ideas and helps new collaborators understand the logic behind the plan.
Know when a change is a pivot
A pivot changes an important hypothesis such as the segment, problem, value proposition, channel, revenue model, or solution approach while preserving useful learning.
Change one major assumption at a time when possible. Define the new test and the evidence required before investing deeply in the new direction.
