A development constitution defines project strategy, features, interaction flows, data schemas, and visual surfaces to prevent ad-hoc architecture decisions and inconsistent UX during software project initiation.

To define a project constitution, draft a five-layer structure covering strategy, core features, critical user journeys, data schemas, and visual guidelines, enforcing schema-first workflows and clear architecture constraints.

Yes, the framework enforces schema-first updates, interaction-level requirements, and clear architecture constraints, while also limiting heavy third-party libraries without explicit approval to ensure maintainability.

You need a product constitution when initiating or scoping software projects to ensure product and engineering teams have cohesive target users, core features, and critical user journeys defined before development.

The five-layer structure limits heavy third-party libraries without explicit approval and requires strict adherence to schema-first updates and interaction-level requirements, which may restrict rapid ad-hoc prototyping.
