ABSTRACT
Since the inception of the software industry, modeling tools have been a core product offered by commercial vendors. In fact, the first software product sold independently of a hardware package was Autoflow, which was a flowchart modeling tool developed in 1964 by Martin Goetz of Applied Data Research (Johnson, 1998). Although software modeling tools have historical relevance in terms of offering productivity benefits, there are a few limitations that have narrowed their potential.
