How a Kamishibai Board Works in Manufacturing

Efficiency and clear communication are indispensable on the manufacturing floor, where every detail counts. The Kamishibai board enhances both aspects with remarkable effectiveness. Explore how this simple Japanese technique can streamline your production process and improve operational efficiency, encouraging a deeper understanding of its potential impact.

What is a Kamishibai Board?

A Kamishibai board is an innovative tool for visual audit management, particularly embraced by organizations practicing Lean manufacturing. This tool utilizes a system of color-coded flags displayed on a wall-mounted board to indicate the success or failure of various procedures at a glance. This immediate visual feedback allows the production team to quickly determine which processes have met quality standards and which require further review or corrective action.

The Origins

The simplicity of the Kamishibai system supports daily quality control management, fostering a collective responsibility among all team members to maintain smooth operational processes. Interestingly, while the Kamishibai board is a modern lean management tool, its roots can be traced back to ancient Japan. Originally, “Kamishibai” or “paper theater” was a storytelling method used by Buddhist monks in the 12th century to convey moral stories to those who were illiterate, using simple visual cues and narratives.

The principles behind Kamishibai boards mirror those found in other Lean methodologies, such as the poka-yoke technique aimed at minimizing errors through simplification. By employing visual signals, Kamishibai boards streamline the communication of audit statuses, ensuring that any issues are identified and addressed promptly. In essence, these boards serve as a bridge between ancient storytelling traditions and contemporary quality management practices, offering a straightforward yet effective strategy to enhance organizational efficiency and accountability.

Kamishibai Board and Total Productive Maintenance (TPM)

• Role in TPM: Kamishibai boards are utilized within Total Productive Maintenance frameworks as essential tools for auditing and verifying process compliance. These visual management tools significantly enhance the oversight capabilities over various TPM activities.
• TPM Objectives: Total Productive Maintenance aims to holistically improve all aspects of an organization, including employee engagement, safety measures, and equipment maintenance. The ultimate goal is to maximize operational efficiency and reduce incidents of waste, downtime, and accidents.

Continuous Monitoring and Improvement

• Ongoing Oversight: Successful TPM implementation requires consistent monitoring and adjustments. Kamishibai boards facilitate this by providing a visual and accessible means for quality personnel to perform regular audits and evaluations of production processes.
• Empowering Process Owners: Kamishibai boards grant process owners autonomy, enabling them to proactively manage and improve their respective areas. This can lead to the establishment of preventative maintenance schedules, which are more effective than reactive approaches and help avoid unplanned downtimes and safety risks.

Benefits and Implementation

• Autonomous System: Setting up a Kamishibai board system lays the groundwork for a self-regulating production environment. It encourages preventative actions and allows for the early detection and resolution of potential issues before they escalate.
• Visual Management: The use of Kamishibai cards displayed prominently within the facility offers an easy-to-understand visual representation of maintenance activities. This visibility ensures that management and team members alike can quickly assess the status of maintenance efforts and adjust accordingly.

How Manufacturers Can Create a Kamishibai Board

Decide Where to Put the Board

For a Kamishibai board to be most effective, it should be positioned in a location that is both central to the work area and highly visible to all team members involved in the processes under scrutiny. Ideal placements include the entrance to a production zone or any high-traffic area within the audit scope. The board can be a simple whiteboard, pinboard, or a specialized system designed to accommodate Kamishibai cards, ensuring that it is easily accessible for updates and reviews.

Delineate Types of Audits and Their Frequency

Organizing the Kamishibai board requires dividing it into sections that represent different audit processes or departments, such as safety, quality, and cleanliness. Each section should reflect the primary audit categories relevant to your operations, accommodating various audit frequencies, from daily to quarterly. This structured layout helps in planning and visualizing the schedule for regular audits, making it easy for leadership to conduct and manage these inspections efficiently.

Create Your Card System

Kamishibai cards serve a pivotal role in Lean management by offering a dual-sided, color-coded system—green for passing audits and red for failures—that simplifies the audit process. These cards, often utilized as T-cards for their straightforward design that fits into designated slots on the board, or as hanging cards for clear visibility, are essential tools in ensuring process integrity. Each card is meticulously designed to encapsulate the 5W1H (who, what, where, when, why, and how) of each audit process. This comprehensive detailing on the cards ensures that every aspect of the process under review is accounted for, making it an integral part of daily management routines in Lean organizations.

By incorporating these principles directly onto the visual boards, Kamishibai systems standardize the way deviations from the standard output are identified and addressed. The immediate visibility of audit results, through the intuitive color-coded system, enables staff members to recognize and rectify deviations in real-time. This not only promotes a culture of continuous improvement but also makes maintaining and auditing standards a standardized, visible, and straightforward task, directly on the gemba (work floor).

What is the Difference Between a Kamishibai Board and a Kanban Board?

Kamishibai boards and Kanban boards are both used to improve workflows and productivity, but they serve different purposes and operate in distinct ways:

Kamishibai Board:

• Purpose: Primarily used for auditing and process checks within a Lean management system.
• Design: Features dual-sided cards (usually green for pass and red for fail) to indicate the outcome of audits or checks.
• Function: Helps identify and correct deviations from standard procedures in real-time, ensuring quality control and continuous improvement.
• Use Case: Perfect for maintaining and monitoring daily quality standards and operational processes.

Kanban Board

• Purpose: Focused on managing tasks and projects by visualizing work, limiting work in progress, and maximizing flow and efficiency.
• Design: Consists of columns that represent different stages of the workflow, with cards or tasks moving from one column to the next as they progress.
• Function: Enables teams to see the status of any piece of work at any time, helps balance workload, and identifies bottlenecks in the process.
• Use Case: Ideal for project and task management across various industries to enhance productivity and collaboration.
