Little’s Law Explained: The Formula That Drives Lean Flow and Lead Time
Little’s Law is one of the most powerful and simple formulas in Lean Manufacturing and Operations Management.
It connects Work in Progress (WIP), Throughput Rate, and Lead Time — helping you understand and improve flow in any process.
In this video, we’ll explain:
✅ What Little’s Law really means
✅ The difference between Throughput Rate and Cycle Time
✅ How to calculate Lead Time using real examples
✅ How to apply it in manufacturing, services, hospitals, call centers, and
software development
✅ Why it’s the foundation behind *Kanban* and *Flow Management*
Whether you’re a Lean Manager, Production Supervisor, or Quality Engineer, this formula will help you make better decisions about capacity, WIP limits, and customer lead times.
📘 *Formula:*
1) Lead Time = Work in Progress ÷ Throughput Rate
or
2) Lead Time = Work in Progress × Cycle Time
