There can be different options for winning transformation strategies; however, success will always come from rigorous, meaningful execution.
Jean Guillou is a Director with Alvarez & Marsal in France, with more than 17 years of operational management including managing operations of multi-site and multinational organizations, leading transformation programs with multicultural teams and cross functional issues.

He has worked with clients across a range of industries, including aeronautics, automotive, high tech, chemicals and banks and insurance companies. He has worked in France, Poland, the U.K. and Japan.

Before A&M, Mr. Guillou was the industrial director of Anovo Group, the European leader of after-sales support solutions for high-tech products. During difficult market circumstances, he successfully led improvement programs and purchasing initiatives. He also built the new accounting model for the Group and all the subsidiaries, resulting in improved control of international operations and easer share of resources across the group.

Prior to this, he was the industrial performance director at Roullier Group, a €2 billion revenue company, with 15 production facilities across six countries in Europe and Latin America. There, he significantly increased the production capacity and then reallocated the capacity to a new product mix, serving a higher margin for the group.

Previously, Mr. Guillou spent more than seven years with McKinsey & Company, first in the U.K. and then in France. He contributed to the creation of their operations practice, developing a Production System Design Center in the U.K. and then in France. He also led transformation programs for large corporations, including growth issues in aeronautics and lead time reduction, and cost cutting in metals and mining.

For private equity firms, Mr. Guillou led assessments of improvement potential for targeted businesses and managed transformation programs for portfolio companies. He started his career with Thales Electronic Tubes, a French high-tech company, in Warsaw, Poland. There, he significantly increased profitability and led programs for technology transfer between Germany and France for satellite power amplifiers. Additionally, he transferred industrial methods and rapid production ramp up for Thales Group in France, in cooperation with the Japanese Ministry of Industry and Panasonic.

Mr. Guillou graduated from the Ecole Nationale Supérieure d’Arts et Métiers in Paris. A French national, he is fluent in French and English.
