What is a Gemba Walk?
In the manufacturing industry, a Gemba Walk is the action of walking around a factory floor where operations take place in order to reduce Waste and improve processes. Managers perform this operational control to identify discordances with the standard and raise issues. A Gemba Walk is a proactive problem-solving practice of operational control and improvement in factories.
What is Continuous Improvement?

1. Gemba Walks feed the system with opportunities for improvement.
The Gemba Walk is a lean practice that sustains a company’s continuous improvement culture. Recurring issues raised through Gemba Walks are improvement opportunities.
Supervisors and managers can identify daily issues or deviations from the standards and generate improvement opportunities from these issues.
Issues are raised and logged directly where the operations are and where they originate. That way, improvement relies on issues and Wastes experienced directly on the floor. It brings relevant and concrete opportunities for improvement.
2. They are two complementary practices.
Gemba Walks’ goal is to identify issues and act on them proactively before they impact quality, productivity, deadlines, and health & safety.
One of the continuous improvement goals is to continually reduce Waste by eliminating recurring issues once and for all. Continuous improvement requires collecting improvement opportunities from a previous detection of issues or from sought out and spontaneous ideas.
Gemba Walks aim to proactively detect issues and generate improvement opportunities. Continuous improvement gets rid of these recurring issues. Combined, they lead to an enhanced control and an improvement of operations.
3. Workers from all levels can contribute to the improvement process.
Since all management levels should go on Gemba Walks, managers can raise all types of issues, as well as generate improvement opportunities. All managers validate and take action in accordance with their management level, which provides a complete view of opportunities. Also, Gemba Walks facilitate the transfer of issues and opportunities among all levels of management for a bottom-up improvement approach.
With Gemba Walks as an operational control practice, supervisors handle all lines and departments; none are avoided or left aside. It creates a discussion with all employees on the floor that focuses on improvement. Everyone contributes to the improvement process, from frontline workers, team leaders, supervisors, managers, and directors.
Workers are valuable sources of improvement ideas for their department. Engaging frontline teams and employees in the changes begins with the identification of improvement opportunities.
4. Gemba Walks bring context to the proposed improvement opportunities.
Managers raise improvement ideas directly where the problems originate or proactively before they occur and document them not long after the floor tour. This method standardizes how they document improvement ideas.
A thorough documentation of issues provides a more precise understanding once it is time to take action. Moreover, the more information we have about the problematic situation, the easier it is to implement a solution that solves the problem at the source. Supervisors and team leaders get to see the complete history of identification and thus, where the ideas originate.
In the PDCA cycle, Gemba Walks help with the identification of the problems, the analysis of the situation and the creation of a proper action plan. It provides an impartial judgement of the improvement ideas and reduces the daily bias based on what the flavour of the day might be.
5. It gives managers more time to focus on the improvement of projects.
A reactive problem-solving approach never helps with the managers’ busy schedule. In a reactive approach, the detection and the resolution of issues is anecdotal. The detection of issues as well as the resolutions are too anecdotal and reactive. Thus, problems already have an impact on the objectives even before managers can address them. Managers have less control of their time management and have a hard time freeing up time to manage improvement projects.
Gemba Walks promote a proactive problem-solving. Supervisors and team leaders gain time when new problems don’t arise randomly. Since the problems can be identified before they come up, they can be solved on-the-spot with less or no impact on objectives. It is a time-saving operational control which provides more time to focus on improvement.
Managers move from a firefighter mode to proactive and controlled operations.
6. It increases supervisors and managers’ commitment.
One of the challenges for operations managers is promoting a culture of accountability and ownership from all levels of management. It implies commitment towards improvement activities.
Gemba walks help continuous improvement by structuring the identification of opportunities. The easier it is to conduct, the better the adherence to the improvement practice will be. Gemba Walks ensure the systematic presence of supervisors on the floor. It also increases workers’ commitment towards company objectives with a bottom-up improvement practice.
On top of that, we recommend setting goals over their Gemba Walks for how many new improvement opportunities each team leader should come up with every week.
7. Systematic Gemba Walks standardize the identification and documentation of opportunities.
Traditional methods such as the suggestion box or other intermittent and occasional practices do not ensure a continual flow to identify improvement opportunities.
With a standard and daily Gemba Walk structure, organizations standardize the way they identify, log, and document improvement opportunities. Supervisors and team leaders go directly on the floor to ask questions and raise ideas for improvement.
8. The improvement is consistent with the strategic objectives.
The validation list can be built in a way that aligns the detection of issues with the organization’s improvement priorities. That way, managers can validate questions which will help to focus on the right objectives. It facilitates the detection of improvement opportunities in accordance with priorities to focus on value-added activities.
9. The implementation of a Gemba Walk structure in itself can be an improvement initiative.
A way to improve an existing Gemba Walk structure is by perfecting checklists, schedules, goals, priorities and management behaviours.
On the other hand, the implementation of a Gemba Walk structure with standard checklists and schedules is an improvement project that enhances operational control on the factory floor.
Furthermore, some organizations implement a Gemba Walk dedicated to improvement, committed to chasing down Waste.
