Tradeoff studies are a critical tool to provide information to support decision making for discipline engineers, systems engineers, and program managers throughout the system life cycle. Unfortunately, the quality of tradeoff studies is typically inconsistent between organizations and within organizations. This paper reports on part of an INCOSE effort to improve tradeoff studies. Using the proposed INCOSE Decision Management Process, aligned with ISO/IEC 15288, we identify and discuss the most common tradeoff study mistakes of omission and commission. The mistakes of omission are errors made by not doing the right things. The mistakes of commission are errors made by doing the right things the wrong way. In addition, we show how these mistakes can cascade into multiple mistakes with significant consequences to the decision makers, stakeholders, and the system. By using the Decision Management Process and avoiding these mistakes, we significantly increase the quality of the tradeoff study and avoid adverse consequences.
