Together with international partners and OEE users FullFact has developed a standard defenition set for Overall Equipment Effectiveness, The OEE Industry Standard.

Allthough OEE is a shop floor tool, not meant to benchmark, it is certainly possible to use certain elements as usefull reference information considering it is done in the right way.

Several parties, such as production teams, line managers and top management may have a different scope when looking at ‘effectiveness’.
Being aware of those differences, it is possible to calculate different indices representing those different scopes; all based upon the same data.
In the literature we find several attempts to do so, unfortunately they are not always consistent.

Although this definition goes beyond the scope of OEE, it is necessary to have a clear picture on this issue since it determines how to define certain categories within the OEE. The OEE Industry Standard shows the big picture.

For every problem there is only one optimal solution.

So why discover the wheel again..... use the OEE Industry Standard (download the OEE Industry Standard)
