KPI Management Terms and Acronyms
Term/Acronym | Definition |
|---|---|
Dimension | A dimension represents a category in a data set and is used for grouping of KPIs. |
KDR | A UDR type that holds the source data for KPI calculations. The decoded input to the workflow is represented as key-value pairs in the UDR, which can then be referenced in a service model. |

Metric | A metric is the result of a calculation based on one or more values in the KDRs. Various functions define how these values should be aggregated in each period. |
Service Model | A service model is set of objects that defines dimensions, metrics, trees, and KPIs and the relation between these entities. |
Tree | A tree is a representation of a set of paths to dimensions in a service model. |
