processes.
Seven Wastes
Ohno was also instrumental in developing the way organizations identify waste, with his "Seven Wastes" model which have become core in many academic approaches. These wastes are:
1. Delay, waiting or time spent in a queue with no value being added
2. Producing more than you need
3. Over processing or undertaking non-value added activity
4. Transportation
5. Unnecessary movement or motion
6. Inventory
7. Defects in the Product.
Ten Precepts
Ohno is also known for his "Ten Precepts" to think and act to win.
# You are a cost. First reduce waste.
# First say, "I can do it." And try before everything.
# The workplace is a teacher. You can find answers only in the workplace.
# Do anything immediately. Starting something right now is the only way to win.
# Once you start something, persevere with it. Do not give up until you finish it.
# Explain difficult things in an easy-to-understand manner. Repeat things that are easy to understand.
# Waste is hidden. Do not hide it. Make problems visible.
# Valueless motions are equal to shortening one's life.
# Re-improve what was improved for further improvement.
# Wisdom is given equally to everybody. The point is whether one can exercise it.
