The India Development Center of a global wireless communication giant was developing a product - Video Sharing Application - for their client using 3G/IP multimedia-based technologies. This application is used to share live or stored video on mobile phones with or without PS (Packet Switched)/CS (Circuit Switched) calls. The application uses SIP (Session Initiation Protocol) for signaling & RTP (Real Time Protocol) for Streaming.

The product was tested by in-house QA team. However, its offshore QA team spent considerable amount of time in detecting defects related to system level hence there was severe lag in the schedule and delay in final product release. The client management was in dilemma on this anomalous situation. STAG was called in to arrest the defect escapes at system level and enable focused field-testing by client's offshore QA team.

Analyzing the existing test artifacts, it was noted, requirement changes were handled on ad hoc basis, test case documentation were neither exhaustive nor reusable, lacked formal unit testing, defects recorded were not analyzed in-depth for its impact.

We worked to streamline test process, applied core STEM^TM techniques - BEST - in designing test cases aligned to test functionality, compliance to standards, abnormal conditions and end-user scenarios. Defects were analyzed and inputs were given to development team to take corrective actions.

Working closely with the customer resulted in zero defect escapes to field testing thereby reducing the time of overseas QA team on field testing for every release from 3 days to 1 day. The client also benefited in faster test cycle - from 5 days to 2 days - due to proper defect identification and immediate actions.
