Design for Six Sigma (DFSS) is an industry recognized methodology used by Raytheon’s Integrated Product Development System to predict, manage, and improve software-intensive system performance, producibility, and affordability. The Raytheon Integrated Defense Systems DFSS team has developed and implemented numerous leading-edge improvement and optimization methodologies resulting in significant business results. These achievements have been recognized by the Software Engineering Institute and the Institute of Electrical and Electronics Engineers with the 2016 Watts Humphrey Software Process Achievement Award. Best practice approaches used by the team are shared in this report, including the generation of highly effective and efficient test cases using Design of Experiments, process performance modeling and analysis, and cost and schedule risk analysis using Monte Carlo simulation.
