2. PREDICTABLE PRODUCT PERFORMANCE AND CONTROLLABLE ENGINEERING PROCESSES
We support organisations by offering our proprietary SixTheta® design methodology for achieving unambiguous
engineering design of products and components.
Building on the goals of Robust Design,SixTheta® design introduces an operational,tangible and scalable way for
organisations to develop products with predictable performance.
The impacts of SixTheta® design include reduced development time,a higher innovation height and reduced
production costs.In addition,in-market performance of products will be much less influenced by changes in ambient
conditions.
SixTheta® design contains concrete tools and methods that help engineers improve quality of their mechanical design
both with regards to the overall conceptual design architecture and the smallest component details.Our mindset is
that before going into detailed design,we should be able to predict how our solution will perform in tests and in the
hands of the end-user.
In addition to teaching engineers how to design better solutions,SixTheta® design enables a comparison of design
quality of different solution concepts in an objective,quantifiable way thereby eliminating the use of “gut feeling”
when designing products.
By implementing SixTheta® design,organisations will experience that they save time in the development processes
with fewer design and prototype iterations.Furthermore,demands for tolerances and the complexity of measurements
on drawings will be significantly reduced.This results in reduced complexity in the manufacturing processes,a quicker
production ramp-up and lower QAcosts.
SIX SIGMAVERSUS SIXTHETA® DESIGN
In the same way as Six Sigma is an objective measure of production capability,SixTheta® is an objective measure of
design capability.
While the Six Sigma methodology strives to reduce variance by optimising production technologies and processes,
SixTheta® design reduces the sensitivity to variance of a given engineering design thus easing production demands.
The two methods are supplementary:

ORIGINAL NON-COMPLIANT SIXTHETA® DESIGN
NEW COMPLIANT SIXTHETA® DESIGN
Impacts of Six Theta® compliant design on pinhole connection:
• 60% of all critical dimensions removed from drawing
• Tolerance demands from very hard to easy to produce; from 0.025 mm to 0.08 mm
• Better performance of solution with less sensitivity to production tolerances

TRAINING AND CERTIFICATION
Valcon Design offers training and certification in SixTheta® design for both large and small organisations.Also,
Valcon Design has initiated the Robust DesignAcademy at theTechnical University of Denmark,and today the majority
of Danish mechanical engineering students are trained in SixTheta® design.
