It sounds like participants didn’t see the value. That is too bad, but among new learners it can be common.
First, if there weren’t any discoveries on process opportunities as a result of the Value Stream Mapping, I would have a lot of questions about how the Value Stream Map was created. Did one person create the map by himself? Did folks walk the process together first?
Second, I can’t tell you what to implement without seeing the Value Stream Map. While the map is being developed and after it is completed, the teams should use the Value Stream Map to analyze process opportunities, confirm root causes, brainstorm ideas to implement, and design a future state map. As a next step, follow up with the group or facilitator who did theValue Stream Maps, what do they see as next steps?
