Productivity is the efficiency of production. Efficiency is a ratio of an investment and production. If a numerical value is big, efficiency is high, and it will be low if small. It’s common sense. |

These are, so to speak, something like infrastructure maintenance of the
production, and the method and means of the solution to the problem are
almost studied exhaustively and have been standardized. Therefore, these
are not so special and neither difficult. Appropriate results are achieved unless the party concerned is short of motivation. |
|||||||||||||
However, the time to hit the ceiling someday comes on. | |||||||||||||
Because true loss (= quality) is actualized. It's the greatest climax of whether an improvement is really successful. |
|||||||||||||
In the way of the same operating improvement as the former, a quality problem is unsolvable. With the result kept stagnating, if sitting back with folded arms, the motivation of the party concerned will fall certainly. However, a more unsavory thing is |
|||||||||||||
running to a former type quality reform inflexibly just because it's a
problem of quality. That is the method which is regarding quality as "goodness", protecting defective outflow by a severe inspection and securing quality by attention arousing. |
|||||||||||||
There is not the idea of the productivity anymore. On the contrary, sooner or later the past improvement activity burns down because the inspection cost increase which conflicts with a productivity improvement hangs around it. |
|||||||||||||
We'll understand easily how such a mentalistic quality reform is stupid if we know that quality is a loss. |
|||||||||||||
If quality improvement is not advanced as productivity improvement activity,
it's not meaningful. Losses are reduced thoroughly and if productivity doesn't improve, it cannot be said that quality became good. |
|||||||||||||
If defects and claims are left, we'll fall into the vicious circle that
productivity falls and cost increases rapidly. Conversely, if quality is stable, it will link with profits directly only by it. If you'd like to gain, you must be tackling a quality problem earnestly. This is best. |
