 +===== Abstract =====
 +Many companies have adopted Process Aware Information Systems (PAIS) for
 +supporting their business processes in some form. On the one hand these systems typically log
 +events (e.g., in transaction logs or audit trails) related to the actual business process executions.
 +On the other hand explicit process models describing how the business process should (or is
 +expected to) be executed are frequently available. Together with the data recorded in the log,
 +this raises the interesting question “Do the model and the log conform to each other?”. Conformance
 +testing, also referred to as conformance analysis, aims at the detection of inconsistencies
 +between a process model and its corresponding execution log, and their quantification by the
 +formation of metrics. This paper proposes an incremental approach to check the conformance
 +of a process model and an event log. At first, the fitness between the log and the model is ensured
 +(i.e., “Does the observed process comply with the control flow specified by the process
 +model?”). At second, the appropriateness of the model can be analyzed with respect to the log
 +(i.e., “Does the model describe the observed process in a suitable way?”). Furthermore,​ this
 +suitability must be evaluated from both a structural and a behavioral perspective. To verify the
 +presented ideas a Conformance Checker has been implemented within the ProM framework.
