How Gemba Visits Can Benefit Your Metal Forge

July 20, 2017 / , , , , , , , ,


Like most industrial manufacturing segments, metal forges have embraced lean manufacturing and the benefits it can bring. Although not every operation has the resources to undergo a total lean transformation, industry leaders like Jorgensen Forge have adopted simple lean tools and practices to eliminate waste, lower costs, and improve customer responsiveness.

One lean manufacturing tool that continues to gain popularity among operations managers is “going to the Gemba” or taking a “Gemba walk.” This practical lean tool gives management a clear view of what is happening on the plant floor and, more importantly, reveals areas for possible improvement. As explained in the eBook, Five Performance-Boosting Best Practices for your Industrial Metal-Cutting Organization, “Gemba” is the Japanese term for “actual place,” but has been redefined by lean thinkers as the place where value-creating work actually occurs. In a manufacturing environment, this is typically the shop floor. Many lean experts advise manufacturing executives to make time to visit this place—known as taking a “Gemba walk”—so they can see their operation from the front lines.

There are several ways managers can “go to the Gemba.” According to a Target Online article from the Association of Manufacturing Excellence, there are three types of Gemba visits:

  1. Leadership Gemba Visits. In these visits, the focus is on the culture, developing trust, learning more about the operations, and finding ways to improve the working conditions of the team members. These Gemba visits are typically conducted by managers and executives (individually or in pairs). They don’t usually have an agenda or follow a prescribed process. The leader simply goes to the Gemba to engage with the team members in a meaningful way and searches for opportunities to make their work less frustrating and more fulfilling.
  2. Leader Standard Work Gemba Walks. These Gemba walks typically have an agenda or a theme and occur on a regular cadence. These are structured and can be done individually or in groups. Many management teams have standard processes for visiting team huddles, checking hour-by-hour charts, doing 5S audits, or doing safety observations. Others visit the Gemba with a specific theme in mind for the walk, such as reviewing autonomous maintenance practices, learning about kaizen activities, discussing safety procedures, reviewing visual management practices, etc.
  3. Problem-Solving Gemba Visits. Typically, the purpose of a problem-solving Gemba visit is to go to the source of a problem in order to observe it first-hand, talk to those closest to the problem, and determine if countermeasures are needed while working to determine the root cause of the problem. This is also a great opportunity for leaders to talk to team members about the problem-solving process and root cause analysis.

Why are Gemba visits so important? This article from The Leadership Network lists a few ways Gemba visits can be beneficial:

  1. First-hand knowledge is the highest form of information. A regular Gemba walk will give managers transparent and unmediated knowledge that is needed to challenge and validate assumptions made by data.
  2. Perspective is gained through experience. A regular Gemba walk allows managers to understand the challenges employees need to overcome on a daily basis to deliver the results that are being promised in the boardroom.
  3. Both people and process matter equally. A regular Gemba walk will help develop a culture that fixes the problems in a process and not one that blames the people performing the process.

If Gemba visits aren’t currently part of your management strategy, perhaps it is time to explore the ways in which it could improve your operation. To read more about this lean manufacturing tool, check out the slideshare presentation, Gemba 101, or read this overview article from iSixSigma.
