What is a Gemba Walk?

Definition of the Gemba Walk

The Gemba Walk, also known as a field walk, is a managerial practice that involves going to the actual place where value is created – where the work is truly done. The term “Gemba” (sometimes written “Genba”) comes from Japanese and means “the real place” or “where the action happens.” This visual work method is based on the fundamental idea that to truly understand processes and identify improvement opportunities, managers must observe operations directly rather than rely solely on reports or metrics.

The Origins and Principles of the Gemba Walk

Developed within the Toyota Production System, the Gemba Walk has become a cornerstone of Lean management philosophy. This approach revolves around several core principles:

• Go see: Observe processes in action rather than relying on reports
• Ask why: Question to understand the root causes of problems
• Respect: Recognize employees as the experts of their work
• Learn: Continuously learn through real-time observation

The method fits within a broader Kaizen (continuous improvement) approach and aims to create a company culture where improvement is everyone’s responsibility—from top management to frontline workers.

Why Is the Gemba Walk Essential in Continuous Improvement?

The Gemba Walk is a powerful lever in any improvement process because it provides firsthand information on operational reality. It also encourages direct communication across all hierarchical levels. Moreover, it helps identify waste and inefficiencies, contributing to a better understanding of daily challenges faced by teams. This method enhances employee engagement by valuing their expertise and input.

In a context where theory often differs from practice, on-site audits such as the Gemba Walk help reconcile strategic vision with operational realities, making improvement initiatives more relevant and effective.

The Benefits of a Gemba Walk for Businesses

Improving Communication and Collaboration

One of the main benefits of the Gemba Walk lies in its ability to break down organizational silos and foster direct, transparent communication. By visiting the shop floor, managers create opportunities for informal discussions with operational teams. This fosters a shared understanding of challenges and objectives, strengthening mutual trust—essential for participatory management. It also facilitates the flow of information between departments.

This approach helps create a work environment where collaboration is valued, and everyone feels heard and understood—key conditions for a true improvement dynamic.

Identifying Inefficiencies and Waste

The Gemba Walk is particularly effective in identifying various forms of waste (or “muda” in Japanese) that can affect process efficiency:

• Overproduction
• Waiting time
• Unnecessary transport
• Inappropriate processes
• Excess inventory
• Unnecessary motion
• Quality defects
• Underutilization of talent

By directly observing workflows, managers can spot process optimization opportunities that traditional reports might miss. This direct visibility into flow management allows for targeted and relevant corrective actions.

Strengthening Employee Engagement

Regular management presence on the ground sends a strong message to teams: their work matters and their ideas are valued. This approach significantly boosts morale and motivation, recognizing frontline workers’ expertise. It fosters a sense of belonging and contribution to company goals, helping identify training and development needs.

By involving employees in the improvement process, the Gemba Walk becomes a powerful human resources management lever that promotes ownership of change and buy-in to improvement initiatives.

Making Decisions Based on Real Observations

Too often, managerial decisions rely on aggregated data that may obscure nuances and on-the-ground realities. The Gemba Walk confronts assumptions with operational reality, helping understand the specific context of problems and assess the real impact of past decisions. It enables the identification of pragmatic solutions adapted to actual constraints.

This observation-based approach enhances decision relevance and effectiveness, contributing to better overall performance management within the organization.

How to Conduct an Effective Gemba Walk?

Preparing the Gemba Walk: Planning and Objectives

An effective Gemba Walk begins with careful preparation to maximize its value. Key preparation steps include:

1. Clearly define the visit’s objectives (specific problem to solve, process to improve, etc.)
2. Identify priority areas or processes to observe
3. Prepare open-ended questions to guide observation and discussion
4. Allow enough time to observe and discuss without rushing
5. Inform relevant teams in advance to avoid the “surprise” effect

This prior planning helps focus observation on critical aspects while creating a trustful atmosphere for constructive dialogue.

Who Should Participate in a Gemba Walk?

The Gemba Walk team may vary based on objectives, but some general principles apply. Executives and managers should regularly participate in Gemba Walks. Involving subject-matter or technical experts can provide deeper insights. Continuous improvement or quality managers can help facilitate the process. Frontline employees should be fully integrated as partners. Representatives from various departments can also offer complementary perspectives.

The key is to foster a dynamic where everyone feels empowered to contribute, in a participatory management spirit that values collective intelligence.

Best Practices for Observing Without Interfering

The art of the Gemba Walk lies in observing attentively without disrupting ongoing work. Recommended practices include:

• Adopt a humble and curious attitude
• Observe the entire process before asking questions
• Focus on the process, not on individuals
• Ask open-ended, non-blaming questions
• Actively listen to operators’ explanations and suggestions
• Avoid criticizing or proposing immediate solutions
• Take notes discreetly to avoid intimidating staff

This respectful approach captures the reality of work while valuing the expertise of those performing it daily.

Data Collection and Feedback

To turn observations into improvement actions, a structured data collection and analysis methodology is essential:

1. Systematically document observations (photos, notes, diagrams)
2. Hold a debriefing session immediately after the visit
3. Categorize and prioritize identified problems
4. Define corrective actions with responsible persons and deadlines
5. Communicate findings and decisions to relevant teams
6. Plan follow-up visits to verify the effectiveness of implemented actions

This follow-through ensures that the Gemba Walk goes beyond a simple visit to become a true problem-solving and improvement tool.

Examples of Gemba Walk Applications Across Industries

In Manufacturing

Manufacturing, the birthplace of the Gemba Walk, offers many successful applications, such as production management to identify bottlenecks on assembly lines and optimize changeovers to reduce downtime (based on Industry 4.0 principles). Reducing intermediate inventory helps streamline production and identify root causes of recurring quality issues. Improving workstation ergonomics reduces fatigue and accident risk. In this sector, the Gemba Walk has proven its ability to generate significant productivity improvements while enhancing safety and quality.

In the Service Sector

Contrary to popular belief, the Gemba Walk is perfectly applicable to service environments: In hospitals: Optimizing patient journeys and reducing wait times
In banking: Simplifying account opening and credit request processes
In hospitality: Improving customer experience by identifying pain points
In call centers: Optimizing scripts and IT systems to support advisors
Adapting the Gemba Walk to these contexts brings the customer back to the center while improving employees’ working conditions.

In Retail and Logistics Companies

Physical flow management in retail and logistics is particularly fertile ground for Gemba Walks, enabling order picking route optimization in warehouses, reducing vehicle loading/unloading times, improving storage area organization to minimize movement, identifying causes of product damage during handling, and revising reception/shipping processes for more efficiency. In these time-critical sectors, Gemba Walks help identify efficiency gains that directly translate into competitive advantages.

How to Integrate Gemba Walks into Your Lean Strategy?

The Role of Gemba Walks in Lean Methodology

The Gemba Walk is not a standalone practice but is embedded in a broader Lean management approach. It complements other tools and methods to maximize impact, for example by feeding Kaizen workshops with improvement opportunities. It supports visual management by validating its effectiveness on the ground and ensures actual adherence to work standards. It helps identify problems to be addressed through A3 or PDCA and strengthens the 5S approach by assessing daily application. This integration into the Lean tools ecosystem creates a synergy where each practice reinforces the effectiveness of the others in a systemic improvement logic.

Tracking and Evaluating Results After the Gemba Walk

To measure the effectiveness of your Gemba Walk approach and demonstrate its added value, a monitoring and evaluation system is essential. Set up specific indicators linked to identified issues and regularly track the progress of improvement actions. The goal is to quantify achieved gains (productivity, quality, lead times, etc.), celebrate and communicate successes to build support, and analyze challenges to improve the process itself. This structured approach to results measurement not only justifies the time investment required for Gemba Walks but also continuously refines the method to maximize its impact.

Conclusion

The Gemba Walk is much more than a simple factory or office tour—it’s a managerial philosophy that puts direct observation and employee respect at the heart of improvement efforts. By combining methodological rigor with an open mindset, this quality management method can profoundly transform how organizations tackle operational challenges.

For companies committed to operational excellence, the Gemba Walk is an essential tool to align strategic vision with field reality. By fostering authentic dialogue across all organizational levels and valuing everyone’s expertise, this approach contributes not only to process optimization but also to the emergence of a company culture focused on continuous improvement and excellence.
