Project Solution

BSG developed iOS and Android applications for the client's Transportation segment across 4–5 sprints. They implemented the full BLE (Bluetooth Low Energy) communication interface for the batteries and built a component to calculate state of charge and state of health from measured voltage and temperature. They designed and delivered the full user interface for guest and authenticated user modes, created customized versions for customers, and produced roughly twenty screens showing battery health and status. Two dedicated teams (one for iOS and one for Android) were assigned; in total the client worked with 5–6 developers and a project manager. The engagement included iterative sprints, quality-control oversight, and coordination on technical and commercial setup.

Project Outcome

Interim release available on the App Store and Google Play for internal and external piloting
Users reported positive feedback on functionality, look and feel, and response time
Quality control manager assigned to both teams to manage QA
Some delays occurred but the vendor worked overtime and maintained the defined budget limits
