Sustaining the Lean journey produces strong results

Since 1973, family owned Dalco Metals of Walworth has been a premier supplier of flat-rolled steel-processing services to manufacturers throughout the Midwest. John Ring, executive vice president of Dalco, credits this long-term success to the company’s focus on the customer’s needs, close relationships with suppliers, and constant attention to quality in every manufacturing and business process.

“About eight years ago, it seemed that everything pointed toward adopting lean manufacturing methods: a customer recommended we look into lean manufacturing, a classmate in my MBA program recommended 5S (a lean method), and I attended the Manufacturing. Matters! conference and participated in a Lean workshop presented by WMEP.”

Lean Office Cuts Paper Processing Time in Half

5sOrganizationSoon after, Dalco Metals embarked on their Lean journey, with the help of WMEP manufacturing specialist Jerry Thiltgen. The first step in a lean journey is an evaluation of where the organization stands right now by using the Administrative Value Stream Mapping (VSM) process. The VSM  looks at the flow of information from the time a process is triggered until the total task is completed. When a process needs 30 minutes of work but takes a week to get through the system, that process is flagged for review. The keys to successful Lean Office implementation include the involvement of all front office employees in shaping the changes and strong leadership that clearly defines the new direction.  The Value Stream Map at Dalco was a revelation: it took longer to process the paperwork for an order than it took to manufacture the order itself.

“We inherited the system that was used in the office, then added a few steps of our own,” said Ring, “that’s why the process took so long.”  Dalco Metals took action: the new office space addition was completely re-designed to group staff around the flow of the work, rather then in departments. This change, along with other streamlining measures, “we cut the processing time from four days to two,” said Ring.

5S produces a “night and day” difference

ChuckSatisfied with the results of the Lean Office project, Dalco Metals began applying Lean processes to the manufacturing floor.  “I thought our shop was well-organized and clean,” said Ring. “When Jerry Thiltgen suggested using the 5S process to clean and organize our facility, I wasn’t convinced that it would make a big difference.”  Thiltgen said, “5S is far more than just straightening up and cleaning.  It involves reviewing and re-thinking each employee’s activity, and making sure their work area supports their work.”  The 5S system is a Lean process that is organized around the following ideas: Sorting, Setting in Order, Shining, Standardizing and Sustain. The goal is to create specific places for paperwork, tools and equipment so that they can be located within 30 seconds.

The 5S process relies on employees taking control of their work areas and suggesting and implementing improvements. “The results of this process were amazing,” said Ring. “especially considering that the primary language of many of our employees is Spanish.” Luis Lopez, a consultant working with WMEP, assisted in the facilitation of the 5S process and his assistance greatly improved communication and empowered our employees to share their ideas.  “Now employees know their voices are being heard” said Ring. “We’ve made changes to facilitate better communication, including signage in two languages, publishing the employee newsletter in English and Spanish, and providing additional training in two languages.”

“Because of 5S, the plant is clean, open and well-ordered. Everything is labeled, and now if anything is amiss, it can be spotted immediately,” said Ring. “5S has meant a night and day difference in our plant – including great improvements in productivity, quality and safety.”

In the past year, Dalco Metals acted on 225 improvements just on the shop floor, and the quality system has moved to a go/no-go system where employees decide whether to move the product forward in the process at each step along the way. “We are marrying 5S with our ISO system,” said Ring. “Improvements are documented, approved and established as part of the formal manufacturing process.”

Executive Support is Critical

5S is not a static tool – Dalco Metals continually works at sustaining the changes they’ve made and to continually find new ways to make the process better, cleaner, faster and less expensive. “Dalco Metals is a great example of what it takes to generate the benefits of Lean manufacturing over the long-term,” said Thiltgen. “Many companies start lean programs, but lack the stamina and commitment it takes to fully realize the benefits gained when Lean is a way of life.  Dalco Metals has tremendous executive support of Lean – it’s a part of everyone’s job.”

Chuck Ferguson, inside sales and applications manager, agrees. “The ‘sustain’ part of the program is the toughest part. We are trying to ingrain the 5S mentality in everyone’s minds here at Dalco and I think it is working. As long as we have the support of the management, Dalco will continue to operate at peak efficiency.”

Ferguson implemented the following steps to ensure that the company remains focused on 5S:

  • Three monthly 5S committee meetings made up of three employees from each shift. Committee members bring fresh perspective by conducting audits of work spaces in other areas of the company. These audits are reviewed at each meeting and metrics are evaluated. (Audit forms are provided in English and Spanish).
  • A continuous improvement file for major issues is maintained for the executive review.
  • Immediate action is taken on issues whenever possible to prevent complacency and relaxed standards.

Dalco Metals continues to benefit from the quality, efficiency and cost savings resulting from the 5S process. In addition, there are unforeseen benefits, said Ring. “In the past, we had to shut down early to clean and prepare for a customer tour.  Now, our facility is a great selling point for us.  Customers can see that we have a well-organized, quality-focused, clean, and efficient operation. Now, we’re ready for the increase in orders that has already begun after the recession.”
