Mabat Viewer: IA & Permissions Design for a Secure Engineering Document Platform

The Challenge

What Mabat Viewer Was Facing

Mabat's secure document platform served engineers with highly differentiated access permissions, but the IA treated all users identically. Role-based interviews uncovered that senior engineers spent an average of 14 minutes per session navigating to documents they were entitled to view, while junior staff frequently encountered opaque permission-denied errors with no recovery path.

The Solution

What We Built

We designed a role-adaptive IA where the document hierarchy and navigation labels dynamically reflected each user's permission scope. A transparent access model was introduced — surfacing why a document was restricted and who to contact — replacing the silent dead ends. Heuristic evaluation and expert review sessions validated each layer before engineering handoff.
