Title: Desire Lines and Cow Paths in Big Data - Aligning Event Logs and Business Process Models



Abstract: Desire lines refer to tracks worn across grassy spaces - where people naturally walk - regardless of formal pathways. Parallels can be draw between such desire lines and day-to-day work performed in contemporary organizations. One thing is how managers think that people work, and another thing is how people actually work. In this talk, we will see how process mining techniques allow us to automatically discover process models from event logs. These models put into evidence desire lines as well as related phenomena such as cow paths, bottlenecks, and detours. Also, we will see how conformance checking techniques allow us to analyze differences between observed behavior and modeled behavior. The talk will focus on the alignment between process models and event logs and will define four conformance notions. Moreover, it will discuss ways of dealing with big data. In particular, it will introduce a notion of "passages" that can be used to decompose and distribute process mining problems.
