Manufacturing and Theory of Constraints Expert Dr. Lisa Lang Shares Client Success Story

Tanya DiSalvo, President of Criterion Tool, shares her story of how her precision machine shop used Velocity Scheduling System to achieve record profits.

Green Valley, AZ – November 14, 2012 – “Dr. Lisa” Lang, President of the Science of Business and Theory of Constraints expert, is proud to share one of many client success stories. Tanya DiSalvo is the President of Criterion Tool (founded in 1953) and an active member of both NTMA (National Tooling and Machining Association) and PMPA (Precision Metal Products Association).  Tanya has utilized Dr. Lisa’s Velocity Scheduling System at her machine shop to improve on-time delivery and reduce lead times.

Here is an excerpt:

“It’s so different from what we’ve seen in the world of manufacturing that it sounded too good to be true. At first as a team we couldn’t get our arms around it, but Dr. Lisa said she was going to give me my money back if it didn’t work, so we were going to do everything she said.”

They liked the homework, but several of her 30 employees, including her dad, who was then  consulting and observing as he neared retirement, bet some real cash against her that it wasn’t going to work.

“I was pretty sure they thought this was just another flavor of the month. Before VSS we were all frustrated,” she remembers, because they were always  trying to manage the “slop,” as she calls it—the jobs that got bogged down and often carried into the next month,  with select customers always suffering.

Once they saw how the system could facilitate movement of jobs, things started clicking.

“As we worked through the Velocity Scheduling process, we got more and more in control. We could focus our resources where we needed them the most. We didn’t have to monitor the jobs, the deadlines, the priorities anymore.”

“It was all the  same people just changing their focus.”
