Without doubt, one of the most frequent questions we get asked is to explain the difference between Process Modelling and Process Mining.
Most customers we talk to are familiar with Process Modelling tools, having developed process models using software such as Visio, ARIS, and Signavio either as part of an SAP implementation or as part of post go live improvement initiatives.
The question is invariably about how the newer technology of Process Mining fits in. With the advent of technologies such as Celonis Process mining, questions arise as to how the pieces fit together.
Let me see if I can help.
Process Modelling and Process Mining are business process analysis (BPA) methods that form part of an overall improvement methodology known as Business Process Management (BPM). The aim of BPM is to provide a framework that allows businesses to manage and improve their business processes.
Process Modelling and Process Mining should be considered as complimentary methods.
How so ?
In figure1 below, the Process Hierarchy architecture at both a conceptual and execution level are covered by a Process Modelling tool decomposing a 5-level model in this
example. The output of which can be considered an agreed “TO BE” process design model.
Meanwhile, Process Mining is providing real world validation at the Execution level, with 'AS IS' data. This data reveals the true extent of process execution variability from the 'TO BE' process.
The way I like to put it, “Process Modelling defines the field within which Process Mining will play.”
Another view of interoperability is in the way that the Process Modelling and Process Mining methods can inform and improve each other in a continuous improvement cycle.
In figure 2, we can see a representation of 'conformance' co-existence. The ‘TO BE’ process model can be imported from real-world process mining, in cases where existing process models are not available.
The ‘TO BE’ and 'AS IS' can then be compared against each other using process conformance checking algorithms, which highlight steps which are different between the models.
Models can then be adjusted, and conformance can be re-run in an iterative cycle. The models can then be exported to BPMN tools for adjustment and refinement as required.
Irrespective of what tool set you have in your existing locker, or whether you are on the lookout for new tools, you should leverage this concept of modelling and mining co-existence to help you improve your living business processes.
