Design Principle
Collaborative interfaces need to show who is present, who is editing, and how conflicts resolve.
Principle
Collaborative interfaces need to show who is present, who is editing, and how conflicts resolve.
Design action
Show member avatars, cursors/selections, edit locks or conflict hints; use save state and history to explain collaboration outcomes.
Examples
Positive example: Docs, whiteboards, design systems, project planning, and multi-person review flows. Counterexample: Multiple people edit with no presence or conflict signals.
Apply when
Docs, whiteboards, design systems, project planning, and multi-person review flows. Users need to judge state, scope, risk, or next action quickly.
