Modeling always has been at the core of both organizational design and info
rmation systems (IS) development. Models enable decision makers to filter o
ut the irrelevant complexities of the real world, so that efforts can be di
rected toward the most important parts of the system under study. However,
both business analysts and IS professionals may find it difficult to naviga
te through a maze of theoretical paradigms, methodological approaches, and
representational formalisms that have been proposed for both business proce
ss modeling (BPM) and information systems modeling (ISM). This paper sets o
ut to put an order to this chaos by proposing an evaluation framework and a
novel taxonomy of BPM and ISM techniques. These findings, coupled with a d
etailed review of BPM and ISM techniques, can assist decision makers in com
paratively evaluating and selecting suitable modeling techniques, depending
on the characteristics and requirements of individual projects.
