It takes thousands of individual decisions to develop, validate, and verify complex aerospace systems. Those decisions, however, are made by humans—and so are susceptible to cognitive bias. Organizations with mature systems engineering functions have developed overlapping mechanisms—such as review boards, “Red Teams,” and engineering test plans—to mitigate the potential for engineers’ cognitive biases to derail mission success. Unfortunately, these mechanisms can themselves be influenced by cognitive biases. This Virtual Project Management (PM) Challenge will examine how to identify and address cognitive bias in engineering thinking that can adversely affect decision making. During the Challenge, participants will look at examples from NASA, industry, and cognitive science research to identify biases that can influence engineering decision making. In addition, the Challenge will explore “debiasing techniques” that can be applied at the individual or organizational level to support mission success.
