VSM Current State vs Future State compares how a value stream works today with the improved flow, information, and control design the team intends to build.
Definition
VSM Current State vs Future State is the practice of mapping the present value stream and then designing a better future-state value stream. The current state shows actual flow, delays, inventories, information signals, and performance. The future state defines how the stream should operate after targeted improvements.
The gap between the two maps becomes an implementation plan.
History
Value Stream Mapping grew from Toyota material and information flow mapping and became a core Lean method for seeing end-to-end flow. Future-state mapping helped teams move beyond documentation into purposeful flow design.
When to Use
Use current and future state VSM when lead time, inventory, handoffs, scheduling, batching, or information flow problems span more than one process step or department.
Step-by-Step
- Select a product or service family.
- Map the current state by observing actual work and information flow.
- Capture cycle time, changeover, uptime, inventory, queues, demand, and signals.
- Identify waste, bottlenecks, batch points, and information delays.
- Design future-state flow using takt, pull, FIFO, supermarkets, leveling, and quality-at-source logic.
- Define the improvement loops and implementation sequence.
- Assign owners, dates, and metrics.
- Review progress and update the maps as conditions change.
Examples
- Manufacturing: Current state shows weeks of inventory; future state uses pull supermarkets and smaller batches.
- Healthcare: Current state shows patient waiting between departments; future state improves flow and handoff timing.
- Office: Future state removes approval loops and clarifies intake requirements.
Common Pitfalls
- Mapping conference-room assumptions instead of actual work.
- Future state is only a cleaned-up current state.
- No implementation plan from the map.
- Ignoring information flow.
- Improving local steps without reducing end-to-end lead time.
- No owner for value-stream performance.
