What does solution fit measure in a product?

Solution fit measures how well a product addresses the problem it is intended to solve. This concept revolves around the alignment between the product's features and capabilities and the actual needs of the customers facing a particular challenge. Achieving solution fit indicates that the product not only understands the problem thoroughly but also offers a viable and effective solution that resonates with the target audience.

In the context of startup fundamentals, understanding solution fit is crucial for ensuring that resources are directed at developing products that have real value in the marketplace. This measurement is a key part of customer validation and helps identify areas where the product may need adjustments or enhancements to better meet the needs of users.

Evaluating other aspects, such as customer engagement, onboarding efficiency, or the effectiveness of wireframes, while important, does not directly measure how effectively the product delivers a solution to a customer problem. Their relevance comes after confirming that the product itself is well-aligned with customer needs.
