At STAG, we are passionate about testing and come up with methods and build tools to foster an engineering-oriented approach to validation. We understand the principles, techniques of software testing to know what kind of defects we are going after and then device the appropriate test strategy and cases. We constantly update and refine our knowledge from our practical experience from our various projects to our valued customers.

STAG believes that there exists a "Science and Engineering of Testing" that should enable a professional test engineer to guarantee quality. STEM^TM is an embodiment of this Science and Engineering of Testing.

STEM^TM or STAG Test Engineering Method is a combination of techniques, tools, process and metrics that guarantees quality. Technique deals with "Principles/Science", Tools deal with "Application/Implementation" while Process deals with to "How-to-implement" and Metrics deal with "Is it going in the right direction?"
