Transcribed Image Text: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

goal in studying the value stream is to eliminate the non-value-
adding processing steps and tasks.
