A leading mobile networking company invested significantly in remodeling its product architecture and committed to specific timelines to its partner ecosystem. The product under test was developed in VC++ for Windows platform. The product provides to any roaming user the facility of connecting to the Internet to access corporate network resources with security. A secured connectivity was provided by the support of Virtual Private Network (VPN), Personal Fire Wall (PFW) and Antivirus. The client management preferred to consolidate its core strength towards building the product and de-risk quality from development by engaging STAG as its strategic quality partner.

Analyzing historical test artifacts and supporting issues, we setup a new test strategy to understand end user acceptance goal and perform intelligent regression testing - used Interaction Matrix (IM5) - tool from STEM^TM -to identify the scope of regression for every change done to the code due to enhancement or bug fixes. We applied core STEM^TM techniques - BEST, EFF, and CTQ - to strengthen existing test cases in terms of depth and breadth, improve readiness of build and to help uncover defects for different types of tests.

This engagement benefited the client in timely release of product with extensive deployment capability and buy-in from one of its prospect. Further, the client also benefited from savings in rework down by 25% and schedule variance down to 3%.
