Mission Statement
The purpose of the Decision Analysis Working Group is to advance the state of the practices, education and theory of Decision Analysis and its relationship to other systems engineering disciplines.
What is Decision Analysis?
Decision analysis is a philosophy and a social-technical process to create value for decision makers and stakeholders facing difficult decisions involving multiple stakeholders, multiple (possibly conflicting) objectives, complex alternatives,
important uncertainties, and significant consequences
Goals
- Expand and promote the body of knowledge of Decision Analysis and its benefits within the Systems Engineering community.
- Explore emerging technologies and methods for informing and making decisions
- Develop and refine guidance and best-practices for decision analysis
- Encourage use of decision analysis techniques to structure decision making at any organizational level
- Increase awareness, reach, and membership of the DAWG and its content
Outcomes
- Updated INCOSE Decision Management Section of SE Handbook, and SeBoK
- Created “Trade-off Analytics: Creating and Exploring the System Tradespace”
- Delivered tutorial on Decision Analysis and Trade Studies at the previous IS
- Working on Decision Analysis Data Model

Events
Military Operations Research Symposium (MORS)
June 9, 2025– June 12, 2025
U.S. Coast Guard Academy
New London, CT
Participants will be introduced to the Decision Analysis Working Group (DAWG) and how the DAWG serves to improve the decision analysis process and its use in the field of Systems Engineering through the Decision Analysis Data Model (DADM). The presentation will illustrate the group’s methodology to creating the DADM, while also highlighting its intended usage in enhancing the practice.
35th Annual INCOSE International Symposium (IS)
July 26, 2025– July 31, 2025
Rogers Centre Ottawa
Ottawa, Ontario, Canada
This INCOSE presentation will introduce and explore the DAWG's Decision Analysis Data Model, which is designed to support structured, data-driven decision-making within organizations. Attendees will gain an understanding of how the model integrates the Decision Management, analytical techniques, and system lifecycle process to evaluate complex scenarios, assess risks, and compare alternative courses of action. By the end of the session, participants should understand how the model can be used as a tailorable framework to capture decisions while streamlines the process entirely.
