This case familiarizes students to value stream mapping as a tool to improve the process. The value stream identifies all the processing steps and tasks undertaken to complete a product or deliver a service from beginning to end. A typical value stream thus can include both value-added and non-value-added processing steps and tasks. The goal in studying the value stream is to eliminate the non-value-adding processing steps and tasks. Directions: READ through the case study “The Westerville Physician Practice: Value-Stream Mapping” on Pages 445 – 448 of your textbook and answer the following questions in a 500–750 words essay. Draw a current state value stream map indicating the customer, supplier, information flow, and relevant metrics. What is the takt time? What is the total lead time (processing+waiting)? What is the total value added and non-value added time? What is the VA/NVA percentage? How can the system be improved and draw a new value stream map?
