Turn a product brief into a task-tested UI prototype
Prototype one three-screen journey and test it with three people before handing the design to a developer.
Setup time

Quick answer
How does the “Turn a product brief into a task-tested UI prototype” workflow work?
Google Stitch can explore UI and connect prototype screens. The prototype tests whether people understand the journey; backend behavior, data persistence, authentication, and production accessibility require implementation and testing later. It takes about 2-4 hours, uses Notion, Google Stitch, Google Sheets, and follows 4 documented steps.

When to use this workflow
Tools you need
Notion
Workspace
Workspace for docs, databases, calendars, SOPs, and team knowledge bases.
Visit websiteGoogle Stitch
Design
Google Labs design canvas that turns briefs and references into UI explorations and interactive prototypes. Use it for task-flow validation and developer handoff, then implement and test the actual product.

Specify one user task
Write who the user is, the starting point, the action to finish, and how success is observed. Limit the first prototype to three screens and include an empty or error state.
Tool used
Notion
Expected output
A task brief and acceptance criteria
Explore and connect the screens
Provide the brief and approved references to Google Stitch. Choose one coherent direction, align text and spacing, and connect the primary route. Use sample data and label simulated actions in the prototype.
Tool used
Google Stitch
Expected output
A clickable three-screen prototype
Observe three task attempts
Ask three intended users to complete the task without coaching. Record completion, hesitation, misclicks, and misunderstood labels. Revise the two most disruptive issues and repeat those steps.
Tool used
Google Sheets
Expected output
A short usability record and revised prototype
Prepare a development handoff
Export the supported design or code artifacts and list states, responsive rules, component choices, and unresolved questions. Have a developer inspect the output and implement real data flows before release.
Tool used
Google Stitch
Expected output
Reviewed handoff artifacts and implementation scope
Prompt templates
Prompt to adapt
Design three screens for [user] completing [task]. Use [brand references], consistent spacing, readable labels, and one error state. Describe each screen's success condition and what must be implemented beyond the prototype.Automation ideas
- Reuse approved design rules across later screens after the main journey passes its task test.
Common mistakes
- Mistaking a clickable mockup for a functioning product
- Adding screens before validating the main task
