What is VDD? • Value-driven design (VDD) is an improved design process that uses requirements flexibility, formal optimization and a mathematical value model to balance performance, cost, schedule, and other measures important to the stakeholders to produce the best outcome possible. • Requirements flexibility – while traditional design focuses on point requirements, VDD opens up an entire solution space • Formal optimization – allows system and component design engineers to discover the best design in the entire solution space • Mathematical value model – expresses all stakeholder values (customer, business, society) and their interactions into a single measure to convey the needs of the project to every member of the design team.

Proposed Charter The purpose of the Value-Driven Design Program Committee is to develop, mature, document, and release a design method that identifies and optimizes the attributes of the product or system of highest value to its stakeholders. Committee members wll discuss and explore the wide-spread use of optimization throughout the design process, from lead systems engineers to designers at CAD stations. Value-Driven Design (VDD) integrates optimization methods with systems engineering, economic analysis and value management methods. When developed, VDD promises a superior and robust approach to affordability that uses economics as a forcing function, balancing cost, performance, and other design attributes to provide the best design to a wide variety of stakeholders. By using the VDD scorecard, everyone in a program has the perspective to execute the vision of the program leaders. Specific goals of the Program Committee are to: 1) Develop a practical implementation of the VDD process, realizing all the benefits of VDD 2) Transition VDD from theory to practice in large systems design 3) Launch the instruction of VDD in engineering curricula 4) Build a vibrant research community in VDD 5) Eventually assign VDD leadership to an existing TC in the TAC
