Detecting Weasels at Work: A Theory-Driven Behavioural Process Mining Approach.

Stresses and temptations in the workplace foster employee behaviour that is less than desirable. The term weasel has been used to describe employees that exhibit a variety of undesirable behaviour at work, including taking undeserved credit, performing below expectation, shirking work, and making co-workers look bad. While this behaviour has traditionally been hard to detect, contemporary systems record many of our work-related actions and the resulting event logs can be subjected to process mining analysis. In this paper we focus on detecting weasels through the evidence they leave behind in such event logs. We capture a variety of weasel behaviours in the form of patterns and suggest how process mining can be used to unearth this behaviour. The patterns are validated through a survey with relevant stakeholders.
