Overall equipment effectiveness (OEE) is a term coined by Seiichi Nakajima in the 1960s to evaluate how effectively a manufacturing operation is utilized.

It is based on the Harrington Emerson way of thinking regarding labor efficiency.

The results are stated in a generic form which allows comparison between manufacturing units in differing industries.

It is not however an absolute measure and is best used to identify scope for process performance improvement, and how to get the improvement.

If for example the cycle time is reduced, the OEE will increase i.e. more product is produced for less resource.

Another example is if one enterprise serves a high volume, low variety market, and another enterprise serves a low volume, high variety market.

More changeovers (set-ups) will lower the OEE in comparison, but if the product is sold at a premium, there could be more margin with a lower OEE.

A system is a set of interacting or interdependent component parts forming a complex or intricate whole.

Every system is delineated by its spatial and temporal boundaries, surrounded and influenced by its environment, described by its structure and purpose and expressed in its functioning.

The term downtime is used to refer to periods when a system is unavailable.

Downtime or outage duration refers to a period of time that a system fails to provide or perform its primary function.

Reliability, availability, recovery, and unavailability are related concepts.

In computer science, real-time computing (RTC), or reactive computing describes hardware and software systems subject to a "real-time constraint", for example from event to system response.

Real-time programs must guarantee response within specified time constraints, often referred to as "deadlines".

The correctness of these types of systems depends on their temporal aspects as well as their functional aspects.

Real-time responses are often understood to be in the order of milliseconds, and sometimes microseconds.

A system not specified as operating in real time cannot usually guarantee a response within any timeframe, although actual or expected response times may be given.

Measurement is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events.

The scope and application of a measurement is dependent on the context and discipline.

In the natural sciences and engineering, measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the International vocabulary of metrology published by the International Bureau of Weights and Measures.

However, in other fields such as statistics as well as the social and behavioral sciences, measurements can have multiple levels, which would include nominal, ordinal, interval, and ratio scales.
