Document Search

Document search for aviation maintenance technicians

Impact

Improved scanability by clarifying informaiton hierarchy
Flexible and iterative search experience, allowing users to refine results without restarting their search
Featured

In a regulated environment, a technician accessing the wrong document version isn’t just a UX inconvenience, it’s a safety risk.

Overview

Client Brief

Customer portal, MVP was released in 2024.

Objectives

Redesign and improve the overall user experience.


Project Duration

September 2021 - June 2022

Challenges

• Due to a lack of information hierarchy and site organization, customer support team had been receiving a lot of technical support requests.

• The consequences of document errors in aviation are serious. The design needed to eliminate ambiguity around versioning and surfacing the right information at the right moment in a workflow.

Challenges

Portal was information-heavy. The UI needed to display critical details without becoming overwhelming to scan quickly.

Multiple UX designers were working on the project. So part of the challenge was ensuring the portal maintained a cohesive and consistent experience across contributions.

Technicians had habits from legacy tools. The new portal had to feel intuitive without dismissing years of learned behaviour.

Key design decisions

The information architecture was reorganized around tasks rather than tool origin. Instead of

"click here, then here to download manuals, this button Y on top for tasks,"

I focused: what is the technician trying to complete right now, and what do they need to do it?

Documents were categorized accordingly rather than requiring a separate lookup. This wasn't a product that needed to feel exciting. It needed to feel trustworthy and fast to navigate under time pressure.

Result

The product now has an improved information hierarchy with clear action buttons. The team will keep track of the effectiveness of the new design by tracking the user inquiries in the customer support team.

Deliverables

Structuring visual hierarchy for scanability

I explored different ways of organizing dense metadata in list views through wireframes, focusing on clarity in high-information environments. Key explorations included:

  • Differentiating primary vs secondary metadata using typographic hierarchy
  • Making key entities visually dominant over supporting details like dates
  • Reducing visual competition between multiple data points

These explorations aimed to improve scan efficiency in long document lists.

Exploring grid and list views

I proposed and explored supporting both grid and list views to better match different user scanning behaviors.

  • List view optimized for comparison and detail scanning
  • Grid view optimized for visual browsing and faster recognition

Supporting iterative search refinement

I intentionally kept the filter checkboxes and granular category selection to support progressive refinement. Based on the usability testings the team noticed that users tend to adjust filters based on visible results.

Reflection

These initial wireframe explorations helped define the direction of the search experience, particularly around information hierarchy, filter persistence, and flexible view options. While some details were further refined by the team, several patterns were carried through into later stages of implementation, including: filter checkboxes, grid and list views, and granular category filtering.
