Prepare to dive into the world of Gemba and discover how it can reshape your manufacturing floor, drive innovation, reduce waste and propel your organization forward in unexpected ways. We invite you to step onto the factory floor, where the real action happens – welcome to the heart of Lean Manufacturing!
Gemba, a Japanese term meaning “the actual place,” refers to the location where value is created, such as the factory floor or customer interaction site. In business, Gemba is a key concept in lean manufacturing and continuous improvement methodologies. It emphasizes going to the frontline to observe the actual process, identify waste, and find opportunities for improvement. Gemba walks, a structured activity undertaken by management, play a crucial role in maintaining disciplined adherence to lean process designs and fostering continual improvement throughout the organization. While initially developed by Taiichi Ohno at Toyota, the concept of Gemba can be applied in various industries beyond manufacturing, including movie production and knowledge-based work like software development. Embracing Gemba practices can lead to enhanced operational efficiency and quality outcomes.
In the context of lean manufacturing and continuous improvement, Gemba is a key concept that refers to the frontline or ‘the actual place’ where value creation occurs. It emphasizes going directly to the source to see the actual process and identify waste in real-time. The Gemba walk is an essential tool for leaders to manage operations actively, engage with workers, and respond quickly to problems.
Origins and Purpose
The origins of Gemba can be traced back to Toyota’s production system in Japan, pioneered by Taiichi Ohno, an executive at Toyota. He believed that management should pay frequent visits to the production floor and observe ongoing operations to identify opportunities for improvement continually. This approach involves using empirical evidence from Gemba observations rather than second-hand information when making decisions.
The purpose of Gemba walks is twofold – they help managers identify areas of waste in the production system and promote employee engagement in identifying solutions. When used effectively, these walks promote a culture of continuous improvement on the shop floor and throughout the organization.
- Edwards Deming, a prominent American statistician who is known for contributions in quality control, also stressed this idea of looking at processes as a whole system. His emphasis on “fostering continual improvement” ties Gemba into one of his key principles.
For instance, suppose a supervisor is performing a Gemba walk on the factory floor and observes a worker physically moving parts back-and-forth repeatedly instead of automating the process. In that case, they can take corrective action immediately, ensuring better-quality products and reduced wastage.
Gemba can also be applied beyond manufacturing to other industries and types of work such as software development or movie production. That being said, there are concerns regarding whether some organizations interpret its meaning correctly while executing Gemba in their organizations.
Gemba in Different Industries
While gemba is a lean manufacturing concept most often associated with factories and production floors, other industries have also embraced the practice. For instance, in movie production, gemba refers to the set, where filming takes place. Knowledge-based work like software development has also adopted gemba to refer to the actual location where coding occurs. Most notably, healthcare organizations who strive towards continuous process improvement have utilized gemba within patient care units.
In a hospital setting, the emergency department may be considered as a gemba site, where management and frontline staff can collaborate to streamline workflows while simultaneously improving patient experience.
Regardless of the exact site’s location, the focus of gemba remains the same – identifying waste and inefficiencies through learning from frontline workers.
- According to a study conducted by the Lean Enterprise Institute in 2020, 75% of organizations implementing lean management practices used regular Gemba walks as part of their strategy.
- The same study found that organizations using Gemba walks saw productivity improvements on average by 30% within the first year of implementation.
- In a survey by the Association for Manufacturing Excellence in 2023, approximately 70% of respondents said that Gemba was instrumental in helping identify waste and improve processes within their organizations.
Significant Benefits of Gemba
The application of gemba can produce many benefits for organizations that believe in a Lean process-oriented culture. Some key benefits are:
- Helps identify waste: One key benefit of gemba walks is identifying inefficiencies and wastes that would otherwise go unnoticed. This allows for immediate corrective measures that lead to substantial improvements throughout all aspects of operations.
- Provides unfiltered insights: Visiting the actual site where value is initiated helps managers gain insight from frontline employees who know how things are done best. These observations can provide valuable insight into processes and potential complications unknown to management or processes that need correction.
- Promotes employee engagement: Gemba walks serve to create an environment that fosters improved trust between employees and management. This strategy provides opportunities for constructive feedback and creates buy-in and ownership among employees contributing positively to morale.
- Increases collaborative working relationships: Gemba walks encourage cross-functional collaboration involving teams from different functional areas operating in synergy to solve process-related problems together.
Think of it like going on a safari – being at ground level gives you an unparalleled understanding of your surroundings and a unique insight into the lives of the animals living therein.
Furthermore, though gemba has its roots in Lean manufacturing, it’s evident how these strategies can improve various aspects of other sectors. This is why many organizations have incorporated similar practices to aid them in continuous improvement across various industries.
Unfiltered Insight and Problem Identifications
In today’s competitive market, companies need to be highly efficient and actively seek continuous improvement. One key ingredient to this success is identifying problems strategically, promptly and resolving them effectively. This is where ‘gemba’ comes into play. By standing at the forefront of a company’s operations, managers gain significant insights that can guide their next steps towards eliminating waste while continually improving production quality.
Gemba provides an opportunity to identify opportunities for improvement, enhance customer experience, reduce costs and eliminate operational inefficiencies. By gaining unfiltered insights, managers can quickly move forward with corrective action plans and ensure smooth running operations with minimal interruption.
When implemented correctly, gemba has significant benefits in various industries ranging from manufacturing to software development to movie productions. It emphasizes going to the frontline to see the actual process firsthand and identify waste.

Gemba has proven to be beneficial across industries such as manufacturing, software development, and movie productions. Implementing gemba correctly can result in significant improvements and a streamlined operation with minimal disruption.
The Gemba Walk Process
One way companies can implement gemba concepts is by conducting gemba walks aimed at improving the entire production system. The walk involves management visiting the working area – whether it is on the factory floors, customer interaction sites or other production departments – to observe workers completing specific tasks. The management team engages with employees, which facilitates bringing together a shared understanding of work processes and enables quick identification of potential process issues.
Some benefits of implementing a gemba walk include: | Increased insight into daily operations | Enhanced communication | | Improved efficiency | Reduced wastage | | Instant feedback | Greater collaboration between teams |
Let’s consider a warehouse scenario: During a gemba walk through the department, management realizes that certain products are mislabeled or misplaced on shelves when there’s still in-demand stock left elsewhere. This realization leads to a strategy shift which ultimately led to less time spent figuring out correct orders later in the process downstream.
Furthermore, by focusing on employee engagement during gemba walks, management can identify potential areas of conflict, issues affecting productivity, and possible areas for process optimization. The crucial success factor for a Gemba Walk is that it should be done with clear goals; otherwise, it could have minimal impact on the system.
Planning, Observing, and Reflecting
To reap the most substantial benefits of Gemba walks, it’s essential to plan them carefully. This involves establishing a clear goal that aligns with Lean principles and specific metrics to measure progress towards achieving that goal. The organization needs to communicate these goals to all employees and ensure everyone is on board.
Once the goals are set, managers can begin observing the actual process a few times before analyzing the data collected. During the observation stage, you should refraining from making any changes but focus on gaining an in-depth understanding of what’s happening on the ground. It provides a clearer picture of what works well and areas that require improvement.
After careful observation, it is now time for reflection. The objective here is to identify waste and inefficiencies in the process while working on actionable measures for elimination continually. This phase should not be overlooked as it’s where actionable insights for progress emerge.
Avoiding Gemba Pitfalls and Misuses
Like every other management concept today, gemba isn’t immune to misconceptions and misinterpretations. Several pitfalls might require attention when embarking on a Gemba walk journey:
Firstly, using Gemba walks for micromanaging employees can incur resentment rather than respect. It defeats the purpose of optimizing processes for maximum efficiency but becomes a method for scrutinizing individuals rather than looking at system-level issues holistically.
Secondly, failure to consistently execute Gemba walks or follow through on identified strategies could lead to inefficient systems falling back into bad practices.
Thirdly, without engaging employees and understanding their perspectives regarding current processes fully, significant opportunities may be missed during observations and reflections.
Let’s say you work in a manufacturing plant that produces automobile parts. While conducting gemba walks, you observe employees taking several trips across warehouses to collect different materials due to poor routing. After collecting this data, instead of creating standardized procedures with your team or engaging them to develop solutions, you unilaterally call for automated storage and retrieval systems (ASRS) implementation on the factory floor without consulting other stakeholders. This pitfall in Gemba walks is a misapplication of the concept, as it fails to engage stakeholders in generating insights.
Lastly, an overreliance on observations and data collection without taking action can lead to pointless data gathering exercises and potentially demotivate employees who want to see changes as a result of their input.
