The efficiency and effectiveness of business processes are usually evaluated by Process Performance Indicators (PPIs), which are computed using process event logs. PPIs can be insightful only when they are measurable, i.e., reliable. This paper proposes to define PPI measurability on the basis of the quality of the data in the process logs. Then, based on this definition, a framework for PPI measurability assessment and improvement is presented. For the assessment, we propose novel definitions of PPI accuracy, completeness, consistency, timeliness and volume that contextualise the traditional definitions in the data quality literature to the case of process logs. For the improvement, we define a set of guidelines for improving the measurability of a PPI. These guidelines may concern improving existing event logs, for instance through data imputation, implementation or enhancement of the process monitoring systems, or updating the PPI definitions. A case study in a large-sized institution is discussed to show the feasibility and the practical value of the proposed framework.

基于日志质量评估和改进过程性能指标的可测量性

业务流程的效率和有效性通常由流程绩效指标 (PPI) 评估,PPI 是使用流程事件日志计算的。只有当 PPI 是可衡量的,即可靠的时候,PPI 才具有洞察力。本文建议根据过程日志中的数据质量来定义 PPI 可测量性。然后,基于该定义,提出了 PPI 可测量性评估和改进的框架。对于评估,我们提出了 PPI 准确性、完整性、一致性、及时性和数量的新定义,将数据质量文献中的传统定义与流程日志的情况联系起来。为了改进,我们定义了一套指导方针来提高 PPI 的可测量性。这些指南可能涉及改进现有的事件日志,例如,通过数据插补、实施或增强过程监控系统,或更新 PPI 定义。讨论了一个大型机构的案例研究,以展示所提出框架的可行性和实用价值。
