Enhancement methodology that focuses on
incremental changes or solutions to eradicate or cut down on defects
or defectives, costs and/or cycle
times leaving the main design and hypothesizes
of a process or service intact.
With a six sigma plan, this should be a
continuous process using methodologies such as PDCA,
(Plan Do Check Act) and follow DFSS,
(Design for Six Sigma) tactics.
Can be implemented using tools such as DOE,
(design of experiments), PPDR,
(post production design reviews), FTA,
(Fault Tree Analysis), Pareto
plots, cause and effects diagrams
and Genichi Taguchi's loss function among
