* Enhancement of performance improvement frameworks: Performance improvement frameworks such as DMADV or DMAIC rely on planning, assessment, and analysis.

Six Sigma was envisioned to be a quality improvement program that reduces process variation to the point where there are only 3.4 unacceptable defects per million process applications through the use of DMAIC and DMADV
improvement strategies coupled with the deployment of a structured set of quality tools (Kumar et al., 2008).
, a Design for Six Sigma (DFSS) methodology, is implemented during the design or redesign phase of a process to minimize the likelihood of problems emerging in the first place.

The other two types of Six Sigma improvement models that are used by Motorola are the DMADDD and DMADV
. The scope of this article is insufficient to get into details of the differences among the three processes; the purpose here merely is to advise the reader that there are two other processes.
is a data-driven quality strategy for designing products and processes and is an integral part of Six Sigma.
Within Six Sigma are two basic sub-methodologies for measuring results: DMAIC (define, measure, analyze, improve, control), used when existing processes have fallen below acceptable levels and incremental improvement is desired; and DMADV
(define, measure, analyze, design, verify), used when new processes or dramatic improvement in existing processes are desired.
DFSS methodology follows a Define-Measure-Analyze-Design-Verify (DMADV
