The Value Stream Mapping skill provides specialized capabilities for creating and analyzing value stream maps (VSM) using Lean principles. This skill enables visualization of material and information flows, identification of waste, and development of future-state improvements for process optimization.
Create a current-state value stream map for:
[Process description with steps]
Include time metrics and identify waste at each step.
Calculate process cycle efficiency:
[Process steps with value-added and non-value-added times]
Compare to industry benchmarks and recommend improvements.
Identify all eight types of waste in this process:
[Process description]
Quantify waste impact and prioritize elimination opportunities.
Design a future-state value stream map:
Current State: [Current VSM details]
Improvement Goals: [Target metrics]
Apply Lean principles and show expected improvements.
This skill integrates with the following business analysis processes:
| Icon | Name | Description |
|---|---|---|
| Process Box | Process | Value-adding process step |
| Triangle | Inventory | Work-in-progress or finished goods |
| Arrow (push) | Push Flow | Material pushed to next step |
| Supermarket | Pull System | Controlled inventory buffer |
| FIFO Lane | FIFO | First-in-first-out flow |
| Kaizen Burst | Improvement | Identified improvement opportunity |
| Electronic Info | Information Flow | Electronic information transfer |
| Letter | Waste Type | Examples |
|---|---|---|
| D | Defects | Rework, scrap, errors |
| O | Overproduction | Making more than needed |
| W | Waiting | Idle time, queue time |
| N | Non-utilized talent | Underused skills, ideas ignored |
| T | Transportation | Unnecessary movement of materials |
| I | Inventory | Excess stock, WIP buildup |
| M | Motion | Unnecessary movement of people |
| E | Extra-processing | Over-engineering, redundant steps |
| Metric | Definition | Formula |
|---|---|---|
| Lead Time | Total time from order to delivery | Sum of all process and wait times |
| Cycle Time | Time to complete one unit | Processing time per unit |
| Takt Time | Rate of customer demand | Available time / Customer demand |
| PCE | Process Cycle Efficiency | Value-Added Time / Lead Time |
| Industry | Typical PCE | World Class |
|---|---|---|
| Manufacturing | 5-10% | 25%+ |
| Service | 1-5% | 15%+ |
| Healthcare | 1-3% | 10%+ |
| Software | 5-15% | 30%+ |
