We rigorously test application by keeping test plans, control and test documentation, apply test tools and techniques and follow checklist for various levels of testing. We organize acceptance test to determine whether the finished system meets the customer requirements specified in the user specification and is acceptable to the end user and prepare acceptance test plan and specification. We have a Documentation team under R&D who produce master lists to control all documents and data related to the project and the system. And they also create documents according to the Document style manual if applicable.
