What it is
Often produced by UX, but PMs frequently sketch them to communicate intent. Keeps requirement debates concrete without committing to visual design.
Concrete example
Balsamiq or FigJam frames showing revised scheduling calendar layout with notes about hierarchy and key interactions.
When to use it
When the team is debating requirements through paragraphs of prose. A wireframe usually settles it in 10 minutes.
What Product Joi delivers
Low-fidelity wireframes for the key screens, annotated with hierarchy, key interactions, and the question each screen answers.
