About Our Client
Our client is a Canadian utility services provider managing operations such as pipeline inspections, equipment maintenance, and infrastructure audits. With hundreds of field technicians operating in remote and low-connectivity environments, ensuring seamless data access and task management was a major operational challenge.
Challenge
The company relied on a legacy mobile system that struggled with:
- Poor offline performance technicians often couldn’t access tasks or forms in no-signal zones.
- Delayed reporting due to manual syncing back at headquarters.
- Fragmented tools for scheduling, logging, and reporting lead to inefficiencies and human error.
- Device limitations, as field workers used both mobile and rugged desktop devices.
The client needed a unified, cross-device platform that worked reliably offline and streamlined field operations.
