Visual Management Tools and Set-Up Reduction Drive Quality and Production Gains

Red banner with logo:

“We’ve really seen a culture of continuous improvement emerge with the mandatory use of visual boards. It’s become a habit to check the scheduling boards to help keep the jobs flowing. It’s now our standard way of operating."

—Ibrahim Ibrahim, Lynn Welding Company, Inc.


Lynn Welding is an industry leader of welding and machining for the Aerospace, Defense, Nuclear, Industrial, and Medical industries. The company started in 1979 as a one-man shop with a Tig welding machine. Named after the original owner’s daughter, company ownership changed hands in 2007. The business is located in Newington, Connecticut.



The ability to weld, machine, and fabricate entire assemblies is what differentiates Lynn Welding from the competition. The company holds an extensive list of qualifications from a broad list of customers and is highly respected within the aerospace community when it comes to producing X-Ray quality welds. Customers consider Lynn Welding the ultimate solution for complex welding and machining.

  • Challenge

    The management of Lynn Welding identified areas of opportunity for improvement including the high cost of finished goods inventory, longer than desired lead times, decreased capacity, and the challenge of sustaining lean initiatives.


    The issues in these areas have led to lower on-time deliveries, higher overtime costs, and an excessive number of expedited orders. Lynn management turned to CONNSTEP for help in streamlining processes to improve quality, cost, and delivery as well as establishing and replicating best practices across the company.

  • Solution

    CONNSTEP recommended a two-phase approach, which included Value Stream Mapping (VSM) of a fabricated product family and coaching kaizen teams.


    CONNSTEP conducted a VSM exercise which identified current steps and sequences followed in one of Lynn Welding’s fabricated products. It also highlighted external quality issues, such as incomplete order information, and some internal issues, which needed greater attention.


    The Lynn team used the current state value stream map to identify areas of improvement. Coaching of the Lynn Welding implementation teams was done to help them build towards a streamlined future state.


    A CONNSTEP consultant also worked on set-up reduction principles focused on creating standardized work procedures for one welding booth and then applying the standardization to Lynn’s other welding booths.

  • Result

    The VSM looked at a key fabricated product family and identified improvements that included 5S, visual management, and reducing batch size. Set-up reduction focused on welding and welding booth operations which was successfully applied to other booths within the organization.


    These improvements resulted in:


    • Production scheduling board – this became a visual tool that gave visibility into what was going on with the job, aligning what to work on now vs. what is in the pipeline
    • Point of use storage – exposed any abnormalities such as not having the right tools or materials, ensuring whatever an employee needed to do their job was immediately available to them
    • Welding Booth Standardization – resulted in better product quality, shorter set-up time, which translated to shorter lead times and greater efficiency

Connecticut is one of several states partnering with a new nonprofit organization to help workers thrive in an AI world and support job growth in the new tech economy. On Monday, Governor Ned Lamont announced that Connecticut is joining Arkansas, Maryland, and Utah in partnership with RAISE US , an organization bringing together states, employers, workers, and educators to build a workforce infrastructure that supports and trains workers to succeed in a future shaped by AI and emerging technologies. “We need to ensure that Connecticut workers and Connecticut jobs benefit from these breakthroughs and do not get left behind,” said Lamont . In May, Lamont signed legislation to help prepare Connecticut’s workforce with the developing technical skills related to AI by establishing new training programs. “Through this partnership with RAISE US, we are committing to take practical next steps to ensure our state has the policies, coalitions, and resources in place to help workers gain new skills, support families through periods of change, and connect people to growing careers,” said Lamont. RAISE US was co-founded by former U.S. Secretary of Commerce and former Governor of Rhode Island, Gina Raimondo, and former Indiana Governor, Eric Holcomb, the co-chair of the organization’s board of directors. According to a press release from Lamont’s office, RAISE US recognizes that emerging technologies are reshaping the economy and require a collaborative approach that brings together state partners, employers, education and training providers, and innovative public policy. “America has a technology strategy for leading the global AI competition. It does not yet have a people strategy—and we cannot lead without one,” Raimondo said. “If we build the best AI systems in the world and leave millions of Americans behind, we won’t have won anything.” Raimondo acknowledged that while AI will create new jobs and industries, it could also bring significant workforce disruption. The RAISE US website cites projections that AI will create a net 78 million new jobs worldwide by 2030, and that workers with AI skills earn, on average, 68% more than workers without those skills. “We shouldn’t fearmonger, but we can’t pretend our training and worker support systems are ready, either. It’s time for innovative and practical solutions,” said Raimondo. “RAISE US gives state leaders a playbook that connects more Americans with the skills and careers needed in the years ahead,” said Holcomb. He emphasized that workforce development is an “all hands-on-deck moment”, not an issue divided along political lines. “I learned this work gets done at the state level, in partnership with employers—not by mandates from Washington,” said Holcomb. The press release states that RAISE US is partnering with leading global technology companies and labor groups, and is building a set of partnerships to support its research, policy, and employer-engagement work with numerous research and consulting groups. “We’ve assembled the country's leading companies, best economists, and philanthropy at a scale rarely seen—all to advance new ideas and incentives, pilot them with governors and business, and scale what works,” said Raimondo. "I want the workforce of Connecticut to look at the years ahead and see opportunity, not uncertainty,” said Lamont.  For Connecticut manufacturers, the initiative could help strengthen the pipeline of workers with AI and advanced technology skills as companies continue adopting automation and digital manufacturing tools.
