Senior Member of the Technical Staff
My interests broadly construed are in the use and transition of empirical analytic methods to guide the development, maintenance, and acquisition of software intensive systems. My work focuses on improving the practice of measurement and analysis, the improvement of process models and appraisal methods, and the impact and transition of process improvement and other engineering technologies. Related interests are in survey research, experimental design, the visual display of quantitative information, the quantitative analysis of textual information, and tools to support collaborative processes.
A principal author of the Measurement and Analysis Process Area for Capability Maturity Model Integrated (CMMI) models, I am technical lead for the SEI's empirical investigations into the performance outcomes of CMMI-based process improvement. I previously served as co-lead of test and evaluation for CMMI, and I was the international trials coordinator for the SPICE project in support of ISO/IEC 15504.
I came to the SEI in 1990 after teaching at Carnegie Mellon University since 1982. I began working on software development over 40 years ago, initially as a research programmer for custom statistical software, then as a lead programmer/designer for an early decision support system. Immediately prior to coming to the SEI, I was co-principal investigator of a large National Science Foundation funded project for the development and evaluation of integrated programming environments.
Over the course of my career, I have published many papers and made many professional presentations. Since joining the SEI, I served for several years as Secretary-Treasurer of the Foundation for the Empirical Studies of Programmers, was a founding member of the international SPICE trials team, and have participated on the United States Technical Advisory Group for ISO/IEC, SC7/WG10.
