After a course in management of complex systems at CentraleSupélec, I wanted to develop a new perspective on the performance of organisations. The very robust academic base of the Worlds approach and the tools developed by P-VAL now give me complete satisfaction. In 2 years, I feel I have added a string to my bow thanks to the commitment and professionalism I have found at P-Val at all levels. It is a chance to work in a firm on a human scale in which everyone has the opportunity to develop on complex and ambitious missions, but also within our internal projects to be an actor in the development of the firm. Each P-Valien has a key role to play!
