Flow Analysis Tool

Flow Simulation
See why flow beats batching.

An interactive, animated simulation that puts one-piece flow and batch processing side by side in real time. Watch lead time collapse, WIP disappear, and throughput stabilise — then bring that insight to your shop floor.

The Core Insight

Same cycle time. Radically different results.

Two systems with identical work content. What changes is the transfer batch size — and it changes everything.

✓ One-Piece Flow
Move one. Process one.
Lead TimeMinimal
WIP InventoryNegligible
First Unit OutEarly
Quality FeedbackImmediate
Defect ExposureOne unit
Batch Processing
Move a pile. Process a pile.
Lead TimeMultiplied by batch size
WIP InventoryHigh, queuing everywhere
First Unit OutMuch later
Quality FeedbackDelayed by queue time
Defect ExposureEntire batch
Tool Capabilities

Interactive. Visual. Immediately convincing.

The simulation builds intuitive understanding of flow — the kind that sticks in a team workshop far better than a slide deck ever could.

Real-Time Side-by-Side Animation
Watch both systems run simultaneously. The visual gap in lead time and WIP between flow and batch becomes undeniable in seconds — no calculation needed to see it.
Adjustable Parameters
Change batch size, number of process steps, and cycle times to explore how each variable amplifies or reduces the flow advantage. Run as many scenarios as you like.
Live Throughput & Lead Time Metrics
Track cumulative units completed, total lead time, and average WIP in real time. Watch the numbers diverge as the simulation progresses.
Built for Team Workshops
Present full-screen in a kaizen event or lean training session. Use it as an experiential learning tool — let your team predict the outcome before running it.
How It Works

Set it. Run it. Debrief it.

1

Set your simulation parameters

Enter the number of process steps, cycle times, and the batch size you want to test. You can model your actual production scenario or run a simplified illustrative version.

2

Run both simulations side by side

Hit play and watch one-piece flow and batch processing run simultaneously at full animation speed or in slow motion.

3

Compare the outcomes

Review the final metrics: total lead time, first-unit time, and cumulative WIP for each approach. The difference is always larger than people expect.

4

Adjust and explore

Change the batch size and re-run. Show your team how even a partial reduction in batch size delivers significant lead time improvement — building the case for flow on your own numbers.
