Lean Manufacturing

Lean Manufacturing was formalized by Japanese manufacturing to identify the subtle inefficiencies that accumulate into massive losses.

These were identified as muda: waste, as in a waste of time. If we trim off this waste, we can become a lean, mean, efficient machine.

The 7 Deadly Wastes are:

1. Transport: Moving product unnecessarily
2. Inventory: Missing materials critical to process
3. Motion: Moving people unnecessarily
4. Waiting: Stopping processes due to bottlenecks
5. Overproduction: Processing parts not needed yet
6. Over-Processing: Delays due to equipment issues
7. Defects: Making mistakes that must be corrected

These can be remembered as “TIM WOOD”; a vile thief you should avoid!

You may already be living your life lean. For example, when you come home with a truckload of groceries, you face two options:

1. Take two trips to carry in the groceries
2. Push yourself to bring them all in at once!

If you chose option 2, you avoided a wasted Motion from making two trips! You’ve saved yourself some time living lean! This may seem like a small gain, but living with continuous improvement builds on good habits and maximizes our limited resources.

Lean Activities

Even if something works, there are always opportunity for improvements.
