The Jobs to be Done (JTBD) framework is a customer-focused approach that prioritizes product development based on the outcomes customers are trying to achieve, rather than focusing on features. It involves collecting "jobs stories" from detailed customer interviews and sorting them into categories such as main jobs, related jobs, functional aspects, emotional aspects, and social aspects. The framework can help companies understand customer needs in-depth, innovate unique solutions, and uncover untapped opportunities in their target market. It is best used at the beginning of product development or after a fully-functioning product has been established to drive innovation.
