A Kanban chart, also known as a Kanban board, is not a concept directly defined by the Project Management Institute (PMI), but it is a widely used tool in project management, particularly in agile and lean methodologies.

The Kanban chart is a visual representation of work items or tasks that need to be completed, usually organized into columns that represent different stages of the workflow. It provides a clear, real-time view of the status of work in progress and helps teams visualize their work, identify bottlenecks, and improve workflow efficiency.

Key components of a typical Kanban chart include:

1. Columns: Each column on the Kanban chart represents a stage in the workflow, such as "To Do," "In Progress," and "Done." Work items move across these columns as they progress through the workflow.

2. Work Items: Work items, represented by cards or sticky notes, are placed within the appropriate columns based on their current status. Each work item typically includes information such as a task description, assigned team member, and due date.

3. Limiting Work in Progress (WIP): Kanban emphasizes limiting the number of work items allowed in each column at any given time to prevent overloading team members and maintain a steady workflow.

4. Visual Signals: Kanban uses visual signals, such as color-coding or markers, to indicate the status of work items and highlight any issues or blockers that need attention.

5. Continuous Improvement: Kanban encourages continuous improvement by promoting collaboration, transparency, and the identification of opportunities for process optimization and efficiency gains.

While the PMI does not specifically define Kanban charts, they are often used in conjunction with other project management methodologies, such as Agile, to help teams manage and visualize their work and deliver value to stakeholders more effectively. Many PMI-certified project managers and organizations incorporate Kanban practices into their project management processes to enhance agility and responsiveness to changing project requirements.
