Motion

Where it comes from

One of Ohno's seven wastes, rooted in the earlier motion studies of Frank and Lillian Gilbreth in the early 1900s that Lean later folded into muda.

What it looks like

• Operators walking back and forth to a shared tool crib or printer.
• Reaching, bending, or twisting for parts that could sit within arm's reach.
• Hunting for the right tool, fixture, or paperwork because nothing has a home.

Why it matters

Wasted motion slows every cycle and wears people out, raising the risk of strain and injury, while a point-of-use layout with clear visual homes for tools keeps work quick, safe, and repeatable.
