Q: Why is it called “Availability”?

Daniel Högfeldt •    By availability it is meant that the equipment should be available when it is planned to be. A customer does not care if the equipment is available at times it is not needed to produce their products.
What is tried to measure is the equipments reliability to be able to run according to the customer needs, not if the machine is able to run during all working hours during the shifts. Many companies try to always have a machine in work because they perhaps want to fulfill the demands on income from invested capital. This may however lead to a faster production than the takt time, therefore overproduction, the most significant source of waste. (Learning to See)
