Field Service & Inspection Mobile

01 / Business Challenge

• Technicians lost in-progress forms whenever the app assumed a constant internet connection.
• Photo and note uploads sometimes failed without a clear message, which led to repeat visits.
• Contractors and employees used different device fleets, so security setup (including trusted certificates) had to be consistent and supportable.
• Supervisors could not tell which jobs were finished in the field but still “waiting to sync.”.
• Policy required encrypted storage on the device and the ability to wipe lost or stolen hardware remotely.

02 / Our Approach

How we executed this engagement in practice. The phases below describe the delivery rhythm we use across ServiceNow, custom engineering, and mobile programs.

We built a React Native app that saves work on the device first, then uploads in the background with clear sync status and retries. Local storage uses SQLite; photos and forms queue safely until the network is available. Work orders tie to barcodes or NFC tags on assets, and GPS is used only where policy allows. Releases aligned with the client’s mobile device management (MDM) program. Telemetry covers crashes and performance—not the text of private field notes.

• Implemented resilient offline capture: forms, signatures, and batched media upload.
• Built supervisor dashboards in the existing web portal fed by the same sync API.
• Added barcode and NFC asset lookup to reduce wrong-asset closures.
• Integrated OAuth device flows with refresh handling suited to long shifts.
• Shipped staged rollout: pilot region, hardening sprint, then national expansion.
• Documented field playbooks for low-bandwidth troubleshooting and support tiers.
