Validate whether a proposed or shipped feature fits the product, solves a meaningful user problem, and stays differentiated from existing surfaces. Use when reviewing overlap between features, checking product market fit, challenging roadmap ideas, evaluating retention or adoption risk, or pressure-testing new UX against the current product.
