Why do so many Lean implementations fail to deliver stable flow?

Because they ignore the core secret behind Just-in-Time: Heijunka.

In this concise, practical guide, Dr. Mohamed H. Soliman explains how production leveling — or Heijunka — helps organizations:

• Build predictable and stable production schedules


• Reduce overburden, bottlenecks, and downtime


• Align suppliers and internal processes for smoother flow


• Cut inventory without risking stockouts


• Unlock the full potential of Just-in-Time (JIT) systems

Whether you're managing a factory floor or improving service operations, Heijunka is the missing link between demand and discipline — and this book gives you a clear roadmap to apply it.

Achieve flow. Reduce chaos. Level up your operations — the Toyota way.
