pm-state-matrix

A product state matrix enumerates explicit states like normal, empty, loading, failure, and permission denied from a flow to replace guesswork in engineering handoffs. It lists triggers, user-visible feedback, system actions, and risk notes for each state to guide development and testing.

A product state matrix must cover edge cases including loading, empty, failure, permission denied, boundary input, and cancel states. For each state, it documents trigger conditions, user-visible feedback, system actions, and risk notes to ensure complete test coverage across normal and abnormal scenarios.

Document product state triggers and system actions by listing per-row details for each state in the matrix. Each row should specify the trigger condition, user-visible feedback, system action, and risk notes, providing a structured and testable state map from prototype inputs to facilitate QA planning.

Yes, you can generate state matrices for boundary and permission denied cases directly from a prototype. By applying business rules to the prototype flow, the state matrix derivation produces explicit states with associated outcomes and documented boundaries for downstream specs and metrics.

Engineering handoffs often miss critical edge states because prototype inputs lack a structured state map. Deriving a product state matrix explicitly captures boundary inputs, loading, empty, and failure states with clear triggers and outcomes, replacing guesswork with testable documentation.

You need a product state matrix for product management flow analysis when scenarios require explicit happy-path, edge states, and errors across normal, loading, empty, and permission cases. It provides a structured, testable state map from prototype inputs to facilitate downstream handoffs and QA planning.
