"Autonomation [automation with a human touch] changes the meaning of management as well. An operator is not needed while the machine is working normally. Only when the machine stops because of an abnormal situation does it get human attention. As a result, one worker can attend several machines, making it possible to reduce the number of operators and increase production efficiency. [...] Implementing autonomation is up to the managers and supervisors of each production area. The key is to give human intelligence to the machine and, at the same time, to adapt the simple movement of the human operator to the autonomous machines." (Taiichi Ohno, "Toyota Production System: Beyond Large-Scale Production", 1978)
"Autonomation [..] performs a dual role. It eliminates overproduction, an important waste in manufacturing, and prevents the production of defective products. To accomplish this, standard work procedures, corresponding to each player's ability, must be adhered to at all times." (Taiichi Ohno, "Toyota Production System: Beyond Large-Scale Production", 1978)
"'Efficiency', in modern industry and business in general, means cost reduction."
"Establishing (1) a production flow and (2) a way to maintain a constant supply of raw materials from outside for parts to be machined was the way the Toyota, or Japanese, production system should be operated." (Taiichi Ohno, "Toyota Production System: Beyond Large-Scale Production", 1978)
"I feel the most
important point in common between sports and work is the continuing need for
practice and training. It is easy to understand theory with the mind; the
problem is to remember it with the body. The goal is to know and do instinctively.
Having the spirit to endure the training is the first step on the road to
winning."
"In a production plant
operation, data are highly regarded - but I consider facts to be even more
important. When a problem arises, if our search for the cause is not thorough,
the actions taken can be out of focus. This is why we repeatedly ask why. This
is the scientific basis of the Toyota system."
"Just-in-time means
that, in a flow process, the right parts needed in assembly reach the assembly
line at the time they are needed and only in the amount needed. A company
establishing this flow throughout can approach zero inventory." (Taiichi Ohno, "Toyota
Production System: Beyond Large-Scale Production", 1978)
"Needs and opportunities are always there. We just have to drive ourselves to find the practical ones." (Taiichi Ohno, "Toyota Production System: Beyond Large-Scale Production", 1978)
"The first rule of
kanban is that the later process goes to the earlier process to pick up
products. This rule was derived from need and from looking at things
upside-down, or from the opposite standpoint."
"We have eliminated
waste by examining available resources, rearranging machines, improving
machining processes, installing autonomous systems, improving tools, analyzing
transportation methods, and optimizing the amount of materials at hand for
machining. High production efficiency has also been maintained by preventing
the recurrence of defective products, operational mistakes, and accidents, and
by incorporating workers' ideas. All of this is possible because of the
inconspicuous standard work sheet."
"When the problem is
clearly understood, improvement is possible."
"When thinking about the absolute elimination of waste, keep the following two points in mind: (1) Improving efficiency makes sense only when it is tied to cost reduction. To achieve this, we have to start producing only the things we need using minimum manpower. (2) Look at the efficiency of each operator and of each line. Then look at the operators as a group, and then at the efficiency of the entire plant (all the lines). Efficiency must be improved at each step and, at the same time, for the plant as a whole." (Taiichi Ohno, "Toyota Production System: Beyond Large-Scale Production", 1978)
"Costs do not exist to be calculated. Costs exist to be reduced." (Taiichi Ohno)
"Let the flow manage the processes, and not let management manage the flow." (Taiichi Ohno)
"Knowledge is something you buy with the money. Wisdom is something you acquire by doing it." (Taiichi Ohno)
"Machines do not break down; people cause them to break." (Taiichi Ohno)
"People who can’t understand numbers are useless. […] However, people who only look at the numbers are the worst of all." (Taiichi Ohno)
"The production line that never stops is either excellent or terrible." (Taiichi Ohno)
"To understand
means to be able to do."
