Purpose of Kamishibai
The purpose of a kamishibai board is to create a structured approach for regular checks on key processes, ensuring standards are followed consistently and areas for improvement are identified quickly. Kamishibai supports visual management, accountability, and routine auditing, making it easy to track and verify that tasks are completed on schedule. This tool is particularly helpful in maintaining operational discipline, ensuring consistency, and fostering a culture of continuous improvement.
Structure of a Kamishibai Board
A typical kamishibai board consists of cards or tabs arranged on a board, often color-coded or marked to indicate specific tasks. Each card represents a task or area that requires a check or audit. These tasks are rotated, making it possible to keep track of completion, accountability, and areas requiring follow-up.
Key Components
Kamishibai Cards Each card has information about a specific task, such as cleaning an area, checking equipment, or reviewing inventory levels. The card includes the task description, frequency, responsible person, and space for marking completion. Color-Coded Cards Cards are often color-coded (e.g., green for completed tasks, red for incomplete or problem areas) to give a clear visual indication of task status. Rotating Schedule The board is designed to rotate tasks, allowing different tasks to be completed on different days or weeks. This rotation ensures that every area of the process is regularly checked and doesn’t fall through the cracks. Visual Indicators for Accountability Once a task is completed, the responsible team member marks it on the board, usually by flipping the card or writing initials. This creates accountability and transparency in the completion of tasks.
How Kamishibai Works
Assigning Tasks Tasks are assigned to team members according to a schedule, with the expectation that they complete and verify each assigned task within a specific time frame. Conducting the Task The person assigned to the task completes it as per the instructions on the card. Tasks can range from checking equipment functionality, ensuring cleanliness, conducting safety inspections, or verifying inventory levels. Marking Completion Upon completing the task, the team member flips the card to the “completed” side or marks it with their initials. This indicates that the task was checked and completed as required. Follow-Up on Issues If a problem or abnormality is found, it is recorded on the card. This prompts further investigation or corrective action, ensuring issues are addressed promptly. Reviewing the Board Regularly Supervisors or managers regularly review the kamishibai board to ensure all tasks are being completed. The board provides a quick overview of which tasks are up to date and which require further attention.
Benefits of Kamishibai
Improved Accountability Kamishibai makes task ownership and completion visible, holding team members accountable for their assigned tasks. Transparency and Visual Clarity The board provides a real-time view of task status, allowing anyone to see at a glance whether tasks are being completed according to schedule. Consistency in Standards Regular checks through the kamishibai board help maintain high standards and consistency in processes, ensuring SOPs and safety protocols are followed. Early Problem Detection By performing regular, structured audits, teams can identify potential issues before they escalate, improving overall quality and reducing downtime. Encourages Continuous Improvement Kamishibai promotes a culture of continuous improvement by encouraging regular checks, reflecting lean principles like kaizen and jidoka (building in quality).
Example of Kamishibai in Practice
In a manufacturing plant, a kamishibai board is set up near the production line. Each card on the board corresponds to a specific daily maintenance check, such as inspecting machine lubrication, verifying safety equipment, or cleaning workstations. Each day, a team member picks up a card, performs the task, and marks it as complete. If they identify an issue, they document it on the card for further action. The supervisor reviews the board each morning to ensure all tasks were completed, allowing them to identify any unaddressed issues quickly.
Implementing Kamishibai in Lean Organizations
Define Key Tasks: Identify essential tasks that need regular checks, such as maintenance, safety, quality inspections, and housekeeping. Create and Label Cards: Develop clear instructions for each task on the kamishibai cards, specifying the frequency and responsibilities. Assign Responsibilities: Assign tasks to team members on a rotating schedule, ensuring each team member is accountable for completing their assigned checks. Review Regularly: Supervisors should review the board daily or weekly, using it as a tool to monitor task completion and address any issues. Encourage Feedback: Involve team members in improving the kamishibai process, encouraging feedback on tasks and improvements for greater effectiveness.
Conclusion
Kamishibai is an effective visual management tool that brings structure, transparency, and accountability to lean operations. By providing a systematic way to track routine tasks, it helps ensure that standards are consistently upheld, issues are identified early, and improvement opportunities are continuously pursued. Kamishibai supports lean principles by reinforcing daily discipline, fostering responsibility, and helping organizations maintain high-quality processes.
