5What 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.

10Proposed 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
