What lean tool does Tiffany employ by instituting educational classes for her staff to improve their procedure capabilities?

The appropriate lean tool Tiffany employs by instituting educational classes for her staff is Kaizen. Kaizen is a Japanese term meaning "change for better" and emphasizes continuous improvement in processes, products, or services. By organizing educational classes, Tiffany is facilitating team involvement in the continuous improvement process, allowing staff to enhance their skills and procedure capabilities systematically.

This approach aligns perfectly with the principles of Kaizen, which focuses on making small, incremental changes over time to improve efficiency and quality. In a healthcare context, such improvements are vital as they directly impact patient care and organizational functionality.

In contrast, the other options represent different tools and philosophies within the lean methodology. Andon is a visual management tool for signaling problems on the production line, Heijunka refers to production leveling to smooth out the workflow, and Value Stream Mapping is a technique for analyzing the flow of materials and information required to bring a product or service to a consumer. None of these tools specifically focus on educational training and the development of staff capabilities like Kaizen does.
