Automation
Automation has been, and is still, a greatly misused word but its proper meaning and, therefore, its implications, is gradually becoming better understood. It is a concept through which a machine system is caused to operate) with maximum efficiency by means of adequate measurement, observation and control. It involves a detailed and continuous knowledge of the functioning of the system so that the best corrective actions can be applied as soon as they become necessary. Thus automation should produce the optimum result. Unfortunately the word has gathered many wrong and half-wrong associations all of which imply mechanization, which in turn implies unthinking repetitive motion and this is the exact opposite of automation.
