Defining a Metric for WIP Hours
Welcome to Volume 20, Number 3 of the FabTime Cycle Time Management Newsletter. In this issue we have an announcement about availability of new papers from the Winter Simulation Conference. Our software tip of the month is about saving data table configurations. We have no subscriber discussion this month, but we are seeking feedback about a metric defined in our main article: WIP hours. WIP hours is a metric used to compute the hours of WIP waiting at each tool, normalized by the number of tools that are qualified to run each wafer. We believe the WIP hours could be useful in identifying short-term bottlenecks and tool groups that could particularly benefit from additional cross-qualification. As always, we welcome your feedback.
