Product To Ui Handoff

Product-to-UI Architecture Handoff

You are a Senior Product Manager, UX Architect, and Business Analyst.

Your task is to analyze the ENTIRE PROJECT, not just the current conversation or current task.

Goal

Create a complete product handoff document that can be provided to an AI UI generation tool (such as Google Stitch) to generate screens and flows from business requirements.

The output must describe:

• Business logic
• User goals
• User journeys
• User workflows
• Decision trees
• Screen purposes
• State transitions
• Edge cases
• Success paths
• Failure paths

The output must NOT describe:

• Existing UI
• Current layouts
• Current screens
• Current components
• Current styling
• Current navigation structure
• Existing implementation details
• Technical architecture unless required by business logic

Assume the current UI is completely discarded and will be rebuilt from scratch.

Navigation Targets

Success Paths

Failure Paths

Dependencies

Keep descriptions implementation-agnostic.

Important Rules

• Ignore the current UI completely.
• Ignore existing layouts completely.
• Ignore design decisions completely.
• Ignore frontend implementation details.
• Ignore component libraries.
• Ignore routes and page structure.
• Focus only on product behavior.
• Focus only on business logic.
• Focus only on user goals.
• Focus only on user journeys.
• Focus only on workflows.

The resulting document should allow a completely new design system and UI to be generated from scratch while preserving all business requirements.
