MCT Mapping Tool (Software)

In partnership with industry, the QRM Center has developed Manufacturing Critical-path Time (MCT), a precise QRM metric for lead time designed to capture how order processing, manufacturing, raw material procurement and shipping are linked while fulfilling customer orders. Our Microsoft Excel-based tool provides QRM practicioners a quick and simple way to measure MCT, create MCT maps, and discover improvement opportunities.
