Question number 2:

2. Why is OEE important?

OEE is important because it is part of improvement strategies

Calculating OEE is a crucial element of improvement strategies, including Total Productive Manufacturing (TPM) and Lean Manufacturing. By using OEE, it is revealed which machine or process needs to be improved at what point. Without OEE, many losses remain invisible. OEE, when correctly implemented, makes visible all losses on each measured machine.

TPM: A Japanese invention
In 1971, the Japan Institute of Plant Maintenance introduced the concept of Total Productive Maintenance. Eventually, TPM evolved into Total Productive Manufacturing. Around the end of the 1980s, TPM became also known in the Western world. At the end of the 1990s, the first books on OEE were published. They made OEE accessible and feasible for Western production areas. OEE was initially used in TPM to improve processes.

OEE is important because it measures machines, not people

When production goals are not met, it is sometimes tempting to blame the production team, the engineers, or the management. One of the big advantages of using OEE is that it measures machines and processes, not people. The objective of the measurement is improvement. OEE provides a common language for production teams, operation managers, and management.

For teams, it is crucial that everybody understands that the OEE measurement does not criticize people. Its sole purpose is to improve the machine and/or the process. Sharing information is important: It gives a team a common goal.

Is a higher OEE rate better?

It depends on the goals of your business. Do you want the equipment to be more reliable? The quality more consistent? Produce smaller batches? Run faster, or a bit slower yet more stable? The OEE rate can help to determine which improvements are required to meet your business needs.
