Lean IT is different from the traditional methods because it focuses on the test engineers themselves, it enables them to change the processes through a series of local improvements of their test practices. "Thanks to these accomplishements, we are now able to initiate an innovative and successful managerial approach which will benefit our customers, employees and the company as a whole" explained Arnaud Cailleau in this presentation from the Lean IT Summit 2015.
