Epic Hypothesis

Frame epics as testable hypotheses by using an if/then structure to articulate the proposed action, target persona, expected outcome, and validation method before committing to a full build-out.

An epic hypothesis in lean UX makes assumptions explicit by defining an expected user outcome and establishing measurable success criteria to manage uncertainty before development begins.

Design lightweight experiments by defining tiny acts of discovery, such as quick user surveys, to test core assumptions and validate user needs before committing to full feature build-out.

Define validation metrics for a feature hypothesis by establishing specific, measurable criteria during the hypothesis formulation stage to determine if the expected user outcome is successfully achieved.

Use epic hypotheses to reduce the risk of building unvalidated features by making product assumptions explicit and running lightweight experiments to ensure development effort aligns with validated user needs.

Avoid using a hypothesis-driven approach for epics when the feature requirements are already fully validated and certainty is high, as the process is designed to manage product development uncertainty through experimentation.
