Joshua De Bock and Jan Claes
The origin and evolution of syntax errors
in simple sequence flow models in BPMN
2/18 | www.janclaes.info
Context – introductory statements
 Conceptual models are useful
 Conceptual models contain errors
 Syntax errors are the easiest to study objectively
 Syntax errors are the least relevant to study
 To study errors, study the creation process
 Process-data is available for ‘process models’
3/18 | www.janclaes.info
Problem statement
About syntax errors
in simple sequence flow models
 How do these errors emerge?
 What is the earliest moment
that potential errors can be detected?
 Which evolution do errors go through
during modeling?

Data collection
 Tool = Cheetah Experimental Platform
 Task = build sequence flow model
from structured textual description
 Language = subset BPMN constructs
 start event + end event
 XOR gateway + AND gateway (split + join)
 Activity + edge (including label)
 Participants = 126 master students

Conclusion
…from this limited dataset and modeling language
…with this artificial case and participants
Issues are often
detectable at an
early stage

  • 1. 1/18 | www.janclaes.info Joshua De Bock and Jan Claes The origin and evolution of syntax errors in simple sequence flow models in BPMN
  • 2. 2/18 | www.janclaes.info Context – introductory statements  Conceptual models are useful  Conceptual models contain errors  Syntax errors are the easiest to study objectively  Syntax errors are the least relevant to study  To study errors, study the creation process  Process-data is available for ‘process models’
  • 3. 3/18 | www.janclaes.info Problem statement About syntax errors in simple sequence flow models  How do these errors emerge?  What is the earliest moment that potential errors can be detected?  Which evolution do errors go through during modeling?
  • 4. 4/18 | www.janclaes.info How many syntax errors? Send PO to factory Send PO to warehouse Update contact info Update financial info Close file Gateway combines join and split semantics ERRORIRRESOLUTIONCONFUSION
  • 5. 5/18 | www.janclaes.info Syntax error or not? Close file If the model is finished: YES If the model in not finished: NO

  • 8. 8/18 | www.janclaes.info Data collection  Tool = Cheetah Experimental Platform  Task = build sequence flow model from structured textual description  Language = subset BPMN constructs  start event + end event  XOR gateway + AND gateway (split + join)  Activity + edge (including label)  Participants = 126 master students Business Engineering at Ghent University in 2015
