At Smart Automotive Variant.CON in Berlin we.CONECT spoke with Ralf Schäfer, Principal of MBTECH, about a modular strategy to avoid the generation of variance at a early product stage. Industries with big product volumes like automotive, software or consumer industries experience problems in quality and cost due to increasing product complexity. This is where modular product design comes in: The main advantage of modular product design is that it does not manage increasing variance but avoids it in the first place.
