Using bottom-up metrics connected to high quality aspects of process models is trying to bridge the hole of utilization of another two frameworks by non-gurus in modeling but it is largely theoretical and no empirical exams are actually carried out to assistance their use.
Methods of Meta design is used to be a foundation for computation of these complexity metrics. In comparison to high quality framework proposed by Krogstie, high quality measurement aim much more on technological degree as opposed to unique model amount.[eleven]
2. Profile the data for excellent, established targets and thresholds, and monitor these KPIs frequently to remain updated With all the changes in data quality.
Not all gateways are selections, nevertheless. It may be which the continuation with the process is determined by getting keep of more data, or awaiting a selected time, or meeting Another situation.
