Overview
Designed a field operations tool for Bouygues Energies & Services at Paris Airports, enabling airport technicians to track and manage critical equipment availability in real time.
The problem
Technicians coordinated by radio and paper logs
Technicians responsible for maintaining airport equipment had no unified visibility tool. They relied on radio calls and paper logs to coordinate, leading to slow response times and duplicated effort. The airport environment added hard constraints: interfaces needed to work gloved, in noisy conditions, on handheld devices, and update in real time across a large physical site.
How I approached it
On-site observation first, then a single-action model
I started with on-site observation at CDG, shadowing technicians during a morning shift to understand the real workflow — what they checked first, how they communicated status changes, and where the process broke down. From this I mapped a simplified flow: live equipment status dashboard → detail view per unit → status update → automatic notification to team lead. The UI was designed for large touch targets, high-contrast states, and a single-action model per screen.
“Designing for gloved hands, noise, and real-time pressure — if it doesn’t work in those conditions, it doesn’t work at all.”
Results
Delivered and accepted in 6 weeks
Delivered a validated high-fidelity prototype covering all primary user journeys, accepted by Bouygues for development. The project was completed in 6 weeks from discovery to delivery, on time and within scope.
