Process Metric

Process Metric

Business

A Process Output whose purpose is to measure and report some aspect of how the Process Step performed during execution.

A Process Metric is a sub-type of Process Output which records information about the execution of a Process Step. For example, how long it took to complete execution of the Process Step and what percentage of records in the Transformable Input was updated by the Process Step to produce the Transformed Output.

One purpose for a Process Metric may be to provide a quality measure related to the Transformed Output. For example, a Process Step with the Business Function of imputing missing values is likely to result, as its Transformed Output, in a Data Set where values that were missing previously have been imputed. Statistical quality measures, captured as Process Metrics for that Process Step may include a measure of how many records were imputed, and a measure of how much difference, statistically, the imputed values make to the dataset overall. Another purpose for a Process Metric may be to measure an aspect of the Process Step which is not directly related to the Transformed Output it produced. For example, a Process Metric may record the time taken to complete the Process Step or other forms of resource utilization (for example, human and/or IT).

Often these two kinds of Process Metrics will be used in combination when seeking to, for example, monitor and tune a statistical Business Process so its statistical outputs achieve the highest level of quality possible based on the time, staff and/or IT resources that are available.
