Overview

The brief.

12,000 SKUs across nine categories. Managers were drowning in tabs. We built a dashboard that prioritises what's broken first and quietly stays out of the way when things are fine.

The previous tool treated every metric equally — a wall of charts that took thirty minutes to read. Managers needed a surface that triaged itself: what changed today, what's at risk this week, what's safe to ignore.

Key insights
  1. Insight 01

    Triage over transparency

    Managers didn't want more data — they wanted a shorter list of what needs attention.

  2. Insight 02

    Glance density matters

    Above-the-fold had to encode 12 signals without feeling like a cockpit.

  3. Insight 03

    Deltas beat absolutes

    'Change since yesterday' was the most-scanned value in every test.

Approach

How it came together.

  1. 01

    Wrote an information-priority matrix with the head of category before any pixels.

  2. 02

    Designed in two registers — 'glance' (status, deltas) and 'focus' (the one chart you came for).

  3. 03

    Built a custom data-viz kit on top of an existing tokens layer, no third-party charts.

  4. 04

    Iterated on density with real managers, not stakeholders — six rounds before launch.
