- 91. citoolkit.com Further Information Like many other lean tools, developing a value stream map for the sake of doing the map will not help much. You should first have a problem that needs to be solved. Try to be specific and include only what you think is relevant for your situation. For example, if inventories are not part of the problem, it would be a waste to count them. Value Stream Map 91
- 92. citoolkit.com Further Information Problems that are not related to the material or information flow are unlikely to benefit from value stream maps (e.g., administrative areas and indirect areas and support services). They often have no structured flow, and Swim lanes are much better sometimes. Value Stream Map 92
- 93. citoolkit.com Further Information There are many software applications and online services that allow the creation of value stream maps. For example, you can generate value stream maps in Minitab Workspace. Value Stream Map 93
