This paper evaluates the suitability of sequence classification techniques for analyzing deviant business process executions based on event logs. Deviant process executions are those that deviate in a negative or positive way with respect to normative or desirable outcomes, such as executions that undershoot or exceed performance targets. We evaluate a range of features and classification methods based on their ability to accurately discriminate between normal and deviant executions. We also analyze the ability of the discovered rules to explain potential causes of observed deviances. The evaluation shows that feature types extracted using pattern mining techniques only slightly outperform those based on individual activity frequency. It also suggest that more complex feature types ought to be explored to achieve higher levels of accuracy.
