The past decade has witnessed a continuous migration of manufacturing and associated jobs to offshore locations, ostensibly to enable American manufacturers to remain cost competitive in the face of increasing global competition. While our marketplace supports the spirit of competition - and consumers and purchasing agents alike have enjoyed lower pricing, the downside to this has been a loss of jobs (particularly painful during our recent economic downturn), longer lead times, and in many cases, a reduction in product quality.
Since 1945, New Jersey based Douglas Electrical Components (DECo) has built a reputation for supplying a premium product to a select market, including space agencies, the military and the semiconductor manufacturing industry. “On one hand, I knew that for many of our customers, domestic engineering and sourcing was a big plus. But I also knew that price was part of the purchasing decision,” said Ed Douglas, third generation owner and president. “For Douglas (www.douglaselectrical.com), we faced the challenge of maintaining, or even improving, our already industry-leading quality and delivery times, while at the same time increasing our efficiency to help keep our pricing aligned with that of our offshore-sourced competitors.”
As pioneers in the development and practical application of epoxy technology to electrical wire feedthroughs, DECo offers proven solutions and works with customers to develop high quality products for their conductor sealing needs. DECo is an ISO 9001 registered manufacturer of UL-approved electrical and fiber optic feedthroughs, hermetically sealed connectors and cables, explosion proof wire assemblies and turnkey subassemblies for semiconductor manufacturing equipment. Major markets served include automotive, magnetic bearing, power generation and distribution, semiconductor processing, space simulation, military, alternative energy, air conditioning and refrigeration, X-ray, explosion-proof, oil and gas exploration, and glovebox.
“When we really sat down and looked at the challenges we faced, we realized a Lean initiative could provide the solution,” Douglas noted. “But we’re a job shop, manufacturing a wide variety of custom-engineered products in runs sizes ranging from a few samples to a few hundred thousand. At Douglas, we do something different every day. We knew Lean worked in large corporations like the automotive industry, but we initially were not sure what the net would be for our type of business. That’s when Lean consultants PDG Inc. became involved. “I bid three groups to assist us with our Lean transformation. PDG immediately stood out as a great match for our needs, mainly due to the way they indicated they would stay involved throughout the process, working directly on our shop floor.”
PDG was up for the challenge.
“We came in and presented to Douglas in November of 2008,” said John Fischbach, the PDG Lean consultant assigned to lead the Douglas initiative. “They gave us the go-ahead within weeks, and we started the program in the late November, early December time frame, just a few months before the downturn really kicked in.”
“In some ways, we could not have picked a worse time to spend money,” Douglas said. “On the other hand, when the downturn really kicked in we had the time and space to give to our Lean program and Kaizen events that really let us get the most out of the process. While it was a tough decision to make at the time, I am glad we moved forward and made the investment as planned.”
Continuous Improvement, Cell by CellLike all successful initiatives, the DECo Lean project started with a plan. “We began the DECo project with a comprehensive value stream mapping process, performed in conjunction with Lean team leaders and manufacturing floor personnel,” Douglas explained. “Part of this process let us see where opportunities lay for the biggest gains, observations which helped lead us through our cell by cell Kaizen events.”
These activities resulted in a 12-to 18-month action plan of continuous process improvement based on developing a deep understanding of performance trends, errors and defects and developing improvements in the manufacturing process. Each team was encouraged to suggest any changes they thought valid, with no part of any process off-limits. The teams were continuously challenged to take a fresh look at each part of their work flow, with the goal of developing tools that could apply to any project that came through the door.
Out With the Old, In With the NewIn each cell, dramatic improvements and sometimes unanticipated benefits were realized. Tackling the challenges of inventory management, operator motion and re-handling and batching and standard work process issues in the Switchgear Cell, for example, witnessed a more than 50% improvement in lead times and productivity, and the number of product touches were reduced by over half. “For this Lean team, it was a real lesson in discovering the efficiency of One Piece Flow, and the fact that Line Balance really does make the job much easier,” said PDG’s Fischbach.
The Precision Instruments Cell, a work area involved in products for the semiconductor manufacturing market, concentrated on improving batching and corresponding inventory and storage issues, as well as looking at reconfiguring the work cell to incorporate cell-specific features such as integrating the test fixture and packaging elements. The results? Well over 40% improvements in lead times and production efficiency. “This was a real tribute to working with the operators. Ideas straight from the floor were the real key to the successes we saw,” said Fischbach.
High Quality, Fast Turnaround, Competitive Pricing-From a U.S. ManufacturerSeeing numbers like those cited in the work cells above certainly proves the value of Lean, but what do they bring to the business? For DECo, the efficiency gains translated directly into cost control and competitive positioning.
“I would have to say that we achieved all we set out to do, and more,” Douglas said. “Our lead times, our product quality and our pricing are now aligned to maintain our industry leadership position, as well as helping us to remain competitive in the face of increased overseas competition.”
