Macro Perspective
• Define strategic direction (“what”)
• Heavy leadership involvement
• Value Stream Mapping
Micro Perspective
• Identify the tactical “how”
• Heavy frontline involvement
• Metrics-Based Process Mapping

Value Stream Mapping Benefit: Seeing the Whole
17
Value Stream Mapping enables a mapping team to get ABOVE the work
![Page 18: Value Stream Mapping: Talk with Omaha Lean User Group](https://reader033.fdocuments.us/reader033/viewer/2022051515/557cb3bcd8b42a1b0c8b4715/html5/thumbnails/18.jpg)

Work is More Similar Than Not…
…When Viewed from a Macro
Perspective

VSM Aids in Developing Systems Thinking

System Efficiency = Optimal Value Stream Performance
Individual Efficiency = Sub-optimization
