Mind the Long Tail: Understanding the Difficulty of Delay Detection in Business Processes
The finding matters operationally: your PPM model looks good until a critical deadline is missed because the long tail is undertrained. This is a real problem in production, and the paper correctly diagnoses it without offering a solution. For builders: reweight your loss or use quantile regression if you care about delays beyond the mean. Known technique, but the diagnosis is valuable context.
