Replace this with the long-form narrative.
The challenge
The existing app assumed a seated user with two free hands. Technicians were using it on site, one-handed, often in poor light, and were filling in reports hours later from memory.
The approach
We rebuilt the job flow around the bottom third of the screen, enlarged every target, and replaced typed fields with selections wherever the answer was predictable. Reporting moved to the moment the work finished.
The outcome
Reports started being filed on site rather than at the end of the day, and the data got noticeably more accurate.
Results
- 81% of reports now filed on site
- -4 min average time per job report
