The document proposes a Market Readiness Level (MRL) metric to evaluate how ready a new product or service is to enter the market. The MRL is based on existing models and synthesizes them into 9 levels that a product must pass through. At each level, specific outputs and validations are required before advancing to the next level, to ensure the business model is validated and to prevent premature launch. The goal is to evaluate market fit and determine when to invest or launch, similar to how NASA's Technology Readiness Levels assess technology.
