Factors of Process Model Comprehension - Findings from a Series of Experiments
In order to make good decisions about the design of information systems, an essential skill is to understand process models of the business domain the system is intended to support. Yet, little knowledge to date has been established about the factors that affect how model users comprehend the content of process models. In this paper, the authors use theories of semiotics and cognitive load to theorize how model and personal factors influence how model viewers comprehend the syntactical information of process models. They then report on a four-part series of experiments, in which they examined these factors. Their results show that additional semantical information impedes syntax comprehension, and that theoretical knowledge eases syntax comprehension.
