Abstract: Software process modeling has undergone extensive changes in the last three decades, impacting process' structure, degree of control, degree of visualization, degree of automation and integration. These changes can be attributed to several factors. This paper studies two of these factors, the time dimension and the interdisciplinary impact, and assesses their effect on the evolution of process modeling. A literature survey for software process modeling was carried out which provided evidence of how the time dimension and the interdisciplinary impact triggered process evolution and changes in methodology, technology, experience and business requirements. Finally, the paper concludes with a theoretical framework to serve as an illustrative model for the effects of the time dimension and interdisciplinary impact on process modeling evolution. This framework can serve as to develop more advanced models for technological forecasting in software process modeling evolution.
