With MS Excel, it used to take us 3 hours to do a single planning run that covered more than 400 SKUs. Now, we can do several planning runs in 1.5 hours only. We have also reduced our inventory by 15% by applying our standards using the Ortems tool. And there are other gains from production optimization, only sometimes more difficult to quantify, because we see them over the long term; for instance, the savings on operator-level labor cost and on changeovers.
