Keiper Automotive has slashed more than $2 million in costs and saved 100 jobs from layoff — all by reducing waste. Bob Cook, plant manager at the Scanlan Street auto parts manufacturer, hosted a lean manufacturing session at the plant yesterday where 10 manufacturers from different sectors learned first-hand how to cut waste, and what an impact it can have.

“This is not about a reduction in the workforce, it is about reducing waste in the system,” Cook said. “There is a lot to be gained . . . and it is really just common sense.” The lean manufacturing session got its start in November at a mayor’s roundtable on advanced manufacturing. When the issue of cutting waste arose, Cook volunteered to lead a session and the London Economic Development Corp. organized it.

“This information is not proprietary. If these people take it back to their plants and expand on it, we all gain,” Cook said.
