Value stream mapping has been widely used in the manufacturing industry to understand flow. Our MBOE students learned how value stream mapping can be effectively used in a pharmacy setting using a case based on Giant Eagle’s pharmacy, authored by Gary Butler, pictured.
One of the many things that the case addresses is the question that commonly comes up when mapping a value stream in a service industry: Variation in how customers come in. There are peak periods and then there are low periods.
How do you then calculate the demand and takt time? When you draw the current state value stream map, it’s not surprising to see multiple takt times: Shorter during busy times of the day and longer during the slower periods.
In health-care settings it’s very common to have multiple people with varying skills performing various tasks in the process. A value stream can give you the metrics to calculate their utilization, which can help you understand how to allocate resources so that every resource can spend their time on only those activities based on their expertise that add value to their customers.
