Organizing a Kaizen workshop or a Value Stream Mapping (VSM) event is not just about using the right tools and methodologies—it is a structured process that involves people, workflows, and business objectives. These events are not merely about optimizing production flows or reducing waste; they are about creating real, sustainable change.
If you want to improve a critical production area or map a process to identify inefficiencies and optimization opportunities, where should you start?
Getting support from leadership for Value Stream Mapping and Continuous Improvement
The first and most crucial step is to obtain sponsorship from company leadership and process owners. Without the right support from management, the event risks becoming a theoretical exercise with no real impact. The leadership team must be aligned, and the workshop participants must have the necessary time and resources to fully dedicate themselves to the initiative.

Setting objectives to identify bottlenecks, improve productivity, and emliminate waste
Once you have secured leadership support, clear objectives must be set. Some common goals include:
✔ Creating a Value Stream Map to identify bottlenecks and waste.
✔ Optimizing a production area to improve productivity and quality.
✔ Redesigning the layout to reduce unnecessary movements and cycle time.
Once the goals are defined, the next step is to build the Kaizen team.
An effective Kaizen event depends heavily on the people involved. On the team should be the Line operators – They work directly in the process and are the best source of insight into inefficiencies; the Supervisors or team leaders – They facilitate the implementation of improvements and ensure alignment with operations; some Key stakeholders, such as quality engineers, logistics managers, or production engineers – They bring cross-functional expertise; An experienced facilitator – Someone who has led past Kaizen events and can guide the team toward tangible results and a Support role for the team leader – This person helps keep the team focused and coordinates activities.
But there is one more strategic choice that can make a difference: including one or two initially skeptical team members. While it may seem counterproductive, having people who tend to resist change can help turn potential objections into active engagement, allowing them to see firsthand the benefits of improvement.
Preparation key to successful implementation of continuous improvement projects
A successful Kaizen workshop does not happen by chance. Preparation is key and should include:
- Training materials – Presentations on Lean tools and the event’s objectives.
- Data collection sheets – To analyze cycle times, movements, and process inefficiencies.
- Visualization tools – Whiteboards, post-it notes, or dedicated mapping software.
- Measurement tools – If needed, to verify concrete improvements.
Duration and scheduling: A typical Kaizen event lasts three to five days. Anything shorter than three days might not allow enough time to achieve meaningful results, while anything longer than five days could turn into a drawn-out project rather than a focused workshop.
Another critical detail: Participants must be fully dedicated to the workshop, without distractions or interruptions from other work responsibilities.
To better understand how a Kaizen event is structured, let’s explore a real example from a company manufacturing off-highway and material handling components.
The company identified the assembly area as one of the biggest bottlenecks in its production flow. The main issues? Excessive material movement, long waiting times, and poor work balancing among operators.
The event’s goal, agreed upon with management, was clear: improve productivity and ensure on-time delivery to customers.
As the team leader, I coordinated a team that included:6 operators out of 24 working in the department; The department manager and a shift supervisor; A maintenance technician; A time and methods specialist; A safety expert and A union representative, to ensure transparency and encourage engagement.
Production planning was also involved, ensuring that enough finished product inventory was available to continue deliveries to customers during the workshop.
Daily structure of a Kaizen workshop
The Kaizen workshop was structured, day by day with the following schedule:
Day 1 – Training and Current State Analysis
- Introduction to Lean principles and Kaizen tools.
- Measurement of cycle times, movements, and waste (Spaghetti Chart, Work Combination Table).
Day 2 – Defining Countermeasures and the Future State
- Further measurement and analysis of waste and inefficiencies.
- Root cause analysis to identify the main bottlenecks.
- Definition of corrective actions to eliminate non-value-added activities.
- Calculation of Takt Time and workload balancing.
- Redesign of the layout to minimize unnecessary movement.
Day 3 – Implementation and Testing of Solutions
- Mock-up of the new workstation layout.
- Testing the proposed changes in a controlled environment.
Day 4 – Refinement and Optimization
- Data collection to verify improvements in efficiency.
- Fine-tuning of implemented changes based on initial results.
Day 5 – Presentation of Results and Next Steps
- Final data analysis to confirm gains in productivity.
- Development of a follow-up plan to ensure sustainable improvements.
- Final presentation by operators to management and key stakeholders.
Each day concluded with an end-of-day briefing where progress was reviewed with management, and feedback was collected.
The Kaizen event delivered measurable, concrete improvements such as: +10% increase in productivity in the assembly area; -50% reduction in waste, particularly in waiting times and unnecessary movements; On-Time Delivery improved to over 95%, thanks to better production flow synchronization; Operators more engaged and proactive, generating new improvement ideas on their own.
A Kaizen workshop is not just about operational improvements—it is about fostering a continuous improvement culture within the organization.
Its success relies on Thorough planning and clear objectives; A well-balanced team with a mix of skills and perspectives; A hands-on approach, with tangible and measurable results.
When a Kaizen event is executed properly, it not only enhances efficiency and productivity but also transforms the organization and its mindset, creating a workplace where improvement becomes part of the daily routine.
