Evaluate where applying OATS is most feasible. It is important to evaluate where the application testing effort will be most effective and efficient to apply. Focus implementing the OAT testing effort from the perspective of what component(s) of the application would benefit most. Focus on utilizing OAT on the critical areas of the application. For example, one test engineer I know returned from a training class on the OATS technique, impatient to apply it right away. He spent days devising an incredibly elaborate orthogonal array testing system to verify possible query combinations applied through a GUI. This specific application used a GUI front end that allowed the user to select various query combinations by selecting parameters on various pull-down menus\u2014basically an in-house modification of a commercial off-the-shelf (or COTS) system that allowed for various application queries. The COTS tool had already been tested thoroughly by the vendor, but in his eagerness to apply his newly learned technique the test engineer lost sight of the big picture. He applied his elaborate OATS scheme to the wrong area of the system: the already-tested COTS front end. It would have been good enough to simply run a variety of GUI tests to verify that the pull-down selections worked and produced correct results. In this case using an elaborate OATS system was excessive, and the testing effort would have been better focused on verifying the accuracy of the SQL queries (the actual code) and on verifying the data migration. The OATS testing method is a great resource, but it\u2019s important to evaluate where in your application testing effort it will be most effective and efficient to apply, and how much of it to use.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
