Global Case - Exclusion Platform for Leading German Truck Manufacturer
Project Overview

In this case study, I share my experience leading product design and user research for a Power Platform “case-exclusion” application and dashboards for a leading German truck manufacturer (name withheld under NDA). My remit covered the end-to-end UX for the Power App — from persona workshops and flow mapping to building an accessible Figma component library — while supporting a second designer on the Power BI dashboards. The objective was to replace a sluggish, accessibility-flawed legacy tool with a faster, role-aware solution that could scale across 30+ markets and automate complex approval logic.

Outcome at a Glance

Replaced a slow legacy tool with a Power Platform app that automates approvals and scales to 30+ markets.

Story Spine
Problem & Constraints

The in-house “case-exclusion” tool was infamous for 40-second loads, manual email chains and a UI that breached accessibility rules.

Complicating matters:
▫️Holiday crunch — delivery was first pegged for 31 Dec 2024, right through the winter break.
▫️Shifting scope
— deliverables grew as stakeholders realised the legacy dashboard logic.
▫️Data access pain
— Databricks permissions failed several times, blocking QA.
▫️Fragmented management — because multiple Reply subsidiaries were tapped, 5 different PMs cycled in to “help coordinate.” Ownership blurred, decisions slowed, and responsibility gaps emerged.

Insight

Two remote workshops surfaced three clear personas:

Market Requester
Submit large batches of exclusion requests at once, instantly see remaining quota, and receive automated confirmations and status updates.
HQ Approver
Work through a filtered, KPI-specific queue, rely on automatic duplicate and limit checks, and meet strict SLAs aided by progressive reminder nudges.
HQ Admin
View every market’s full queue in real time, override exclusion limits when necessary, and fine-tune country-specific thresholds directly in the dashboard.

Pain-point mapping showed that status opacity and manual limit checks cost ~15 min per request. We framed the product principle:

“Make limits & status self-evident.”
Solution

Design system
I built a Figma component library in one week, then paired with engineers to port tokens to Power Apps. We adjusted brand colours to hit 4.5:1 contrast while keeping the corporate palette.

Role-driven UI
T
he canvas renders columns and actions based on the Rights & Roles matrix.

Automation layer
▫️Power Automate flows trigger all eight email templates and a three-step reminder ladder.
▫️Auto-approval logic consults the Databricks limit table nightly; overrides if case was previously excluded.

Dashboards
Secondary designer led Power BI; I reviewed layouts and injected the exclusion status filter and colour tokens.

Impact

Despite the holiday-season crunch and a staggered rollout, the first production release delivered clear, measurable wins that validated the redesign and set the stage for future feature work:

↓67%
cycle time
5× faster load
8s screens vs 40s legacy tool
34 markets
minor launch bugs surfaced
but were fixed within the first week
Conclusion

Shipping a 5× faster, WCAG-compliant platform to 34 markets — despite holiday absences, shifting scope, and a five-PM shuffle — proved that tight deadlines don’t have to force shallow results. The project’s success hinged on front-loading design systems, automating repetitive checks, and staying ruthless about visible performance wins.

Key takeaways:
✔️ Design tokens pay compounding dividends in multi-role apps.
✔️ Clear SLA nudges (Teams or email) are as valuable as UI polish.
✔️ Performance metrics tell the story better than feature lists when executive attention is scarce.
