Open Workshop Format

• An Open Workshop is always in session, always accessible!– convened November, 1996 – ends November, 2001

• Workshop dialogue via website, e-mail, and list service

• Quarterly newsletter to registrants• 2-3 Supporting meetings annually


Open Workshop Goals• Synthesize a sound theory of Decision-Based Design. • Determine the proper role of decision-making in design.• Develop consensus on defining the DBD perspective.• Establish the role of DBD within design theory and

methodology research.• Build a repository of foundational materials (e.g., a

lexicon, case studies, references) that illustrate design as decision-making.

• Establish a useful relationship between DBD and other theories (e.g., physics, mathematics, information and management science)

• Transfer DBD decision support methods and tools into industry.


What is the DBD Perspective?• Decision-making is a vital part of design.• DBD practitioners view design as a decision-making

process maximizes the value of a designed artifact to both the producer and the end-user.

• Design occurs in an environment characterized by ambiguity, uncertainty and risk, complicating the decision-making process.

• DBD processes emphasize establishing value systems to rank expected outcomes of design decisions and incorporating uncertainty and risk handling in predicting the expected outcomes.

10th Open Workshop on Decision-Based Design

Panel Session on

The Role of Decision Analysis in Engineering Design

September 10, 2000Baltimore, MD

• John RenaudUniversity of Notre Dame


Decision AnalysisDecision analysis is a structured way of thinking about how the action taken in the current decision would lead to a result.

Decision analysis constructs models, logical and perhaps even mathematical representations that allow the decision maker to estimate the possible implications of each course of action and better understand the relationship between the actions and the objectives.


Questions to be Addressed• Should all design activities, including those that might be

intuitive (nonjudgemental), e.g., brainstorming for the generation of design alternatives, be constructed under a decision theory framework?

• Is Multiattribute Utility Analysis a useful method in Engineering Design? What is your approach to engineering decision making that involves multiple attributes and multiple decision makers?

• What are the top research issues for developing DBD approaches to design?

Intuitive - knowing or perceiving without an evident and rational process.
