Why do people struggle with the complexity
of constructing a process model?

Business Process Modeling (BPM)
Assumptions
Constructing process models is useful
Process model quality is important
Business Process Modeling (BPM)
Process model quality
“what is a good process model?”
Process of process modeling (PPM)
“how to make a good process model?”

Impressions (subjective)
Impr. 1. Modelers need serialization
Impr. 2. Structured serialization helps
Impr. 3. Structuring does not help everyone
Impr. 4. Structuring the modeling process
helps structuring the model

Future work
SPMT = theory for explaining reality
Descriptive, not for predicting
Future work = theory for design and action
Prescriptive, differentiation is key
Future work = design science
Tool support
• Measure cognitive style
• Suggest appropriate modeling technique
• Adapt tool to support that particular technique
