WILLEM JANSSEN, CERTIFIED LEAN SIX SIGMA MASTER BLACK BELT
Willem Janssen started working as a quality manager in the steel sector in 1996. Along the way he learned which approaches lead to good results, and this – the search for the right approach to a problem – still gives him a lot of energy every day.
In 2014, Willem received his Lean Six Sigma Master Black Belt certificate from the Lean Six Sigma institute of the University of Amsterdam (IBIS UvA). Only a few people in the Netherlands have met the very strict requirements set by IBIS.
Willem led various Lean Six Sigma projects at the Dutch TV and internet provider Ziggo, saving the company more than €5 million; and under his guidance, Merck reduced their storage facilities by 2,500 units while pallet movements went down to 18,000. These are just a couple of examples of Willem’s outstanding results.
