SOFTWARE DESIGN FOR SIX SIGMA
(DFSS): A PRACTICAL GUIDE FOR
SUCCESSFUL DEPLOYMENT
9.1
INTRODUCTION
Software Design for Six Sigma (DFSS) is a disciplined methodology that embeds
customer expectations into the design, applies the transfer function approach to ensure
customer expectations are met, predicts design performance prior to pilot, builds
performance measurement systems (scorecards) into the design to ensure effective
ongoing process management, leverages a common language for design, and uses
tollgate reviews to ensure accountability
This chapter takes the support of a software DFSS deployment team that will
launch the Six Sigma program as an objective. A deployment team includes different
levels of the deploying company leadership, including initiative senior leaders, project
champions, and other deployment sponsors. As such, the material of this chapter
should be used as deployment guidelines with ample room for customization. It
provides the considerations and general aspects required for a smooth and successful
initial deployment experience.
The extent to which software DFSS produces the desired results is a function of the
adopted deployment plan. Historically, we can observe that many sound initiatives
become successful when commitment is secured from involved people at all levels.
At the end, an initiative is successful when crowned as the new norm in the respective
functions. Software Six Sigma and DFSS are no exception. A successful DFSS
deployment is people dependent, and as such, almost every level, function, and
division involved with the design process should participate including the customer.
