In 1998, Michiel began programming test tools at LogicaCMG. The acquisition of this knowledge allowed him to become involved in the development of the “Testframe” test method in 1999. As a test consultant Michiel co-authored the book about Testframe. At Capgemini in 2000 he was a test manager responsible for various national and international projects. Towards the end of 2002 he was requested to set up a test competency centre and thereafter to run it. The competency centre expanded to employee around 40 staff who carried out projects for customers from the financial world. In mid-2004 he made the move to Business Development at Sogeti. Here he was responsible for the development of new products and services in the specialist areas of quality assurance and testing. At the beginning of 2006 he was one of the authors of a new version of TMap. This resulted in the publication of the book, “TMap Next for result driven testing” in 2007. On February 2008 Michiel became an independent test manager and consultant.
