COMPLEXITY METRICS There were four important questions that we sought to answer in the DARPA Complexity and Adaptability metrics program. These were: 1. What are the complexity and adaptability metrics? 2. Do the metrics correlate with schedule, cost, or reliability? 3. And, can they be used to predict schedule given a conceptual design? 4. Are they useful as a relative metric comparing alternate designs? In this project we address each of these questions.
