Six Sigma in New Product Development
There is an entire roadmap for New Product Development in Six
Sigma. This is referred as DFSS. (Design for Six Sigma) .
Design for Six Sigma (DFSS) is
a Six Sigma methodology that is used to launch new products & services
on time, on budget, and on target gaining incremental revenues sooner,
achieving greater market share, and ensuring that the company generates
differentiated products & services that target customer & stakeholder
needs. DFSS methodology is most commonly used in New Product Development
organizations.
There are several approaches to
DFSS, but the most popular methodology is called DMADV. DMADV stands for
"Define - Measure - Analyze - Design - Validate". The Define phase
consists of defining the project charter which includes the business case and
the opportunity for the new product or service. In the Measure phase, the needs
of the key stakeholders are identified and measurable CTQs are developed. The
Analyze phase consists of subsystem design and generating and selecting the
best possible concepts. In the Design phase, a detailed design for the product
or service is developed and optimized. The robustness of the design is ensured
to minimize the impact of variation on performance of the product or service.
Finally, in the Validate phase, the generated designs are verified and
validated using simulation and other approaches.
Some of the tools covered in
DMADV training are:
Multi-Generational Project Plans (MGPP)- On Six
Sigma projects that have significant scope, it is a good idea to break up the
scope into multiple generations. An MGPP helps a team focus on the current
generation and also plan for what is to come in the future generations.
Analytical Hierarchy Process
(AHP), Kano Analysis, Kansei Engineering, Theory of Inventive Problem Solving
(TRIZ), Quality Function Deployment (QFD), Pugh Analysis, Multiple Regression
Analysis, Fractional Design of Experiments, Taguchi Optimization, and Discrete
Event Simulation methods.
DFSS is a powerful set of tools
and techniques that can help one develop products and services that truly
satisfy the key stakeholder needs. While DMAIC helps reduce bottom line costs
in an organization, DFSS helps develop robust products and services to increase
top line growth.
