SCENE

EXPERIENCES OF A LEAN SIX SIGMA GREEN BELT PROJECT During and after my Lean Six Sigma (LSS) crash course in München in May 2018, I had mixed feelings regarding the upcoming Lean Six Sigma project. I was lucky to have landed a job in the Finnish worldleading company Konecranes, which specializes in the

manufacturing and service of cranes and lifting equipment for ports, shipyards and other industrial environments. However, I felt quite uncertain, as it would be the first time I would work as a project leader and have the true responsibility of a project and its outcome. I also knew that I would be on a very tight schedule and working with products that I had never seen before, in a totally new industrial environment. Looking back now it sounds very interesting and an excellent opportunity to learn, as it was!

achieve. Headless pounding and frustration will not get you anywhere, I can tell you that. The project that I am conducting is for the Hyvinkää gear factory (CHG). The gear factory produces gearboxes and transmission parts of gears for industrial equipment. As you might know, port cranes are gigantic and the largest ones can lift 1200 tons high in the air. As it can be understood the gearboxes of these kind of products cannot be small either. Here’s a picture of a gear box. To give you some scale, the largest ones I have so far seen at the factory are some three meters long and weigh up to 1000 kg, so certainly we are not talking about small objects.
