Sogeti has developed TMap®, the Test Management approach for structured testing (both low-level and high-level) of software products. The method provides answers to the what, when, how, where and who questions of testing.

To structure the organisation and execute the test processes TMap® is based on four cornerstones: 
- a development process related life cycle model for the testing activities (L); 
- solid organisational embedding (O); 
- the right resources and infrastructure (I); 
- usable techniques for the various testing activities (T). 

In recent years TMap® has evolved towards the standard for software testing in the Benelux and Germany. It is being used by more than three hundred Dutch, Belgium and German organisations. Many banks, insurance companies, pensions funds and government departments, but also in market segments such as consumer electronics, telecommunications and medical systems use TMap®.

The TMap® books (in English, German and Dutch) have proven to be best sellers  in many countries, used by many organisations and uncountable professional testers.
