Conformance checking, also known as conformance analysis, is an important element of process mining and business process management. In this article we go through what it is through definitions, examples and best practices.
What is Conformance Checking?
Conformance checking is a method of comparing the execution of a business process against a predefined set of conditions, such as a business process model. It is used to assess the real state of processes and to identify any variations between the should be and the as-is behavior outlined. It is a key component of process mining software, which is the application of data mining techniques to discover, monitor, and improve processes.
Conformance checking can also be called conformance analysis or business process conformance checking.

Conformance checking in BPM
Conformance checking plays an important role in business process management (BPM), which is the systematic approach to managing and optimizing processes in business organizations.
Conformance checking involves analyzing the actual data from a process execution and comparing it to the expected behavior, or process 'happy path.' The analysis can be done based on expert interviews, surveys or increasingly through dedicated process analysis and modelling software. The observed data is analyzed to determine if the process was executed correctly and if it was completed in a timely manner. It can also identify any errors, deviations, or inefficiencies that may have occurred in the process.
The benefits of conformance checking are numerous. It helps to ensure that processes are performed accurately and efficiently. It also allows organizations to identify areas where processes can be improved, thereby increasing the efficiency and effectiveness of their operations.
Examples of conformance checking
There are many real-world examples of conformance checking across different types of businesses and business units. It can also be used to identify any errors or deviations in the process that may lead to inefficiencies or delays.
Logistics - it may be used to monitor the performance of logistics processes in a supply chain.
Customer service - case management evaluating how different customer service records have followed the agreed path and support.
Procurement - tracking how different business units or transactions follow the agreed purchase-to-pay processes.
Claims processing - review of insurance claims processes, whether the claims manager has followed the modelled process.
Conformance checking in process mining
Conformance checking is closely related to process mining, which is the application of data mining techniques to discover, monitor, and improve processes. Process mining uses data from event logs to create a graphical representation of the process. It can also identify any deviations or inefficiencies in the process.Business process management (BPM) is the systematic approach to managing and optimizing processes. It involves the use of methods, techniques, and tools to monitor, analyze, and improve processes.

In conclusion, conformance checking is an important tool for process mining and business process management. It helps to ensure that processes are executed accurately and efficiently and can identify any areas where processes can be improved. By using conformance checking, organizations can gain valuable insights into their processes and optimize their operations.
