QAT Global’s Approach
QAT Global and Atrium partnered together to update the application, document the existing application code, and develop a strategy for a complete upgrade to version 2.0. Faced with extremely tight time constraints for having product ordering and pricing updated for version 1.1, the team leveraged the existing tools and software to achieve the short-term goals. The tightly integrated Caelus pricing engine was successfully severed using software from existing tools and programming languages. QAT Global also used the process of producing “As-Is” Reference Architecture and “To-Be” Reference Architecture documents to provide the Architectural Recommendation and Roadmap for their future desire to move to version 2.0. Our U.S. based development resources also documented the existing application code so the application could be reverse-engineered. In turn, we were able to provide verification of track content, enhancements, and additions, as well as the basis for project cost estimates.
The scope of this project expanded greatly from the original task order, to include nearly twice as many products plus several of the original set turned out to be new, versus copies from the old system. The QAT Global team accepted the challenge and delivered the new requirements on an expanded time frame to ensure Atrium was successful with its upgrade and plans for the future.
