The model we have developed does provide a framework for thinking about the role of new software tools. Software provides two things — ease of use and depth of understanding. The first of these decreases the training time required to become proficient. The second increases quality for both new and experienced modelers.
Keeping the 10% of experienced modelers time for both training and supervision try cutting self training time and min training time in half as an experiment (call this run Quick). Then as an alternative experiment change new quality to 0.6 (call this run Quality).
Both ease of use and quality can have a significant impact on the speed of diffusion. Vensim was designed to provide both ease of use and higher quality results and we hope it will speed the growth of System Dynamics.
