Baseline OEE Codes

The baseline GE Digital APM database contains a set of baseline OEE Codes that define basic OEE Codes. Each OEE code is either a parent code or a child code. In general, parent codes are used to categorize high-level losses, and child codes further divide those categories into more specific areas. Both parent codes and child codes are stored in OEE Codes.

You can also create custom OEE codes. Only the baseline codes and their children, however, will be used to calculate the OEE percentage in the OEE Metric View. Therefore, in order for custom OEE codes to be included in the OEE percentage calculation, they must be children of the baseline parent OEE codes.

The following OEE Codes are provided in the baseline GE Digital APM database.

Important: OEE codes are based on the definitions listed in the 4th edition of SMRP Best Practices Standard. Editing of OEE codes should be coupled with testing of the accuracy of the associated calculations.


Parent Code	Child Codes	Description
Availability	Scheduled Downtime Unscheduled Downtime	Indicates that a production loss is due to resources that are unavailable for use (e.g., scheduled maintenance).
Idle Time	No Demand No Feedstock or Raw Material Not scheduled for production	Indicates that a production loss is due to available resources that are currently not in use (e.g., a piece of equipment is available for use, but there are not enough employees to operate it). Losses associated with the Idle Time OEE code are included in the calculations for other categories (availability, performance, and quality). Idle Time does not represent its own OEE category.
Performance	Minor Stops Reduced Rate	Indicates that a production loss is due to resources that are not performing at 100% capacity.
Quality	Production Rejects Startup Rejects	Indicates that a production loss is due to poor quality product that could not be used.
