Green Valley, AZ – October 10, 2012 – “Dr. Lisa” Lang, President of the Science of Business and inventor of the Velocity Scheduling System is featured in a November 2011 article in The Fabricator and, where she was interviewed about Theory of Constraints and Velocity Scheduling System.  The article also highlights two of Dr. Lisa’s clients, CMI Industry America and Guntert & Zimmerman.  The article, titled “High mix, fast delivery–on time: How high-mix, low-volume fabricators adapt the Theory of Constraints,” was written by Tim Heston.  Tim Heston explores how Dr. Lisa helped both clients utilize the Theory of Constraints to keep the chaos of their manufacturing in check, but allow for dealing with emergencies while increasing productivity.

Dr. Lisa remarks on the negatives of focusing on efficiency.   Below is an excerpt:

TOC goes against traditional manufacturing thinking, in which workers produce more than is needed to reduce the number of setups and maximize the efficiency of all resources. The forecast, after all, says these parts will be needed eventually, so why not produce them now? The problem is, of course, that sales forecasts are notoriously inaccurate, so those parts may never be needed. Also, producing so many unneeded parts floods the floor with work-in-process (WIP), while jobs in queue sit for days or weeks waiting for large batches to work their way through.

Dr. Lisa offers her expertise throughout the article, which explores five main topics: “The Value of Throughput,” “The Importance of Flow,” “Drum-Buffer-Rope for High Mix,” “Full Kit and Accurate Information” and “Enabling Change.”
