AP Imports Redesign

Finance analysts had quietly built workarounds around their primary tool. The business hadn't noticed — which was exactly the problem. This wasn't an interface issue. It was a trust problem.

The problem

Finance analysts and procurement buyers had quietly built shadow systems around their primary tool — spreadsheets, manual checklists, workarounds that lived entirely outside the platform. No escalations on record. Everyone had simply adapted.

The workarounds had become invisible to the business. That adaptation was the real problem — not just a usability issue, but a business cost. The tool wasn't losing users. It was losing volume.

An external supplier, unprompted, during discovery research. The UX problem was costing the business volume, not just user time.

What changed

The research surfaced what no escalation report had: shadow workflows that had become the actual process. That finding reshaped what the redesign needed to do — not improve the tool, but earn back trust from users who had adapted around it. Navigation was restructured around task completion rather than data taxonomy. Exception states were elevated to where users needed them. Approval context was surfaced inline. Satisfaction went from 2.69 to 6.14 out of 7. The usability testing framework became the standard for the broader product area.


Research & discovery

End-to-end: discovery, stakeholder interviews, information architecture, three rounds of usability testing, final designs. The goal was understanding not just what was broken, but why it had stayed broken.

Methods

Key findings

  1. The workarounds were invisible: Because users had adapted quietly, the business didn't see the problem. Escalation data understated severity significantly.
  2. Navigation was organized for the system, not the user: The existing IA reflected data taxonomy rather than task completion. Users had to learn the system's logic before they could do their job.
  3. Exception states were buried: The states users most needed to act on required hunting. The tool surfaced everything equally, which meant nothing was findable.
  4. Approval context was missing at the moment of decision: Approvers were being asked to make consequential decisions without the information they needed to make them confidently.
Getting stakeholder alignment

When I brought the discovery findings to the product team, the initial response was skepticism: the escalation data showed almost nothing, so how serious could the problem be? I had to make the case that a user who stops complaining isn't a satisfied user — they've adapted. Presenting the shadow spreadsheets side-by-side with the support ticket data made the gap concrete. Getting alignment that this needed a trust rebuild, not a feature increment, required three stakeholder sessions and a direct comparison of what the escalation record showed versus what the research surfaced.

Discovery research surfaced three distinct user types with fundamentally different relationships to the tool — each with their own workarounds, priorities, and failure modes.

Design process

The central design challenge wasn't the UI. It was trust. Users had a conditioned belief that the system would fail them. Every design decision had to be evaluated against whether it would build or erode that belief.
