Lean Canvas is a strategic management tool used to create a one-page business plan for a new or existing company. It was developed by Ash Maurya and is based on the Business Model Canvas by Alexander Osterwalder. The purpose of Lean Canvas is to help entrepreneurs and businesses quickly and effectively validate their business ideas and develop a roadmap for growth.

The Lean Canvas consists of nine key elements that are organized into four categories:

Problem: This section defines the target audience and their pain points.

• Customer Segments: Who are the customers or users of the product/service?
• Problem: What are the specific problems or needs of the customer segments?

Solution: This section outlines the unique value proposition of the product/service.

• Solution: What is the product or service that solves the customer's problem?
• Unique Value Proposition: What makes the product or service different and better than the competition?

Market: This section defines the market size and competition.

• Channels: How will the product/service be delivered to the customer?
• Revenue Streams: What is the pricing model for the product/service?
• Cost Structure: What are the major costs involved in creating and delivering the product/service?

Execution: This section outlines the plan for execution and growth.

• Key Metrics: What are the most important metrics for measuring success?
• Unfair Advantage: What unique advantage does the company have that makes it difficult for competitors to replicate?
• Key Activities: What are the most important activities required to create and deliver the product/service?

By filling out the Lean Canvas, entrepreneurs can quickly identify potential flaws in their business idea and make adjustments before investing significant time and resources. Additionally, the Lean Canvas can be used to communicate the business model to stakeholders and investors.
