6 Sigma Definitions

• Six Sigma is a measure of quality with a
  continuous improvement program looking for
  perfection
• Six Sigma is a disciplined, data-driven approach
  and methodology for eliminating defects
• Six Sigma is a data-driven, disciplined approach
  to minimizing defects in any type of process (be
  it manufacturing or services).
• The goal of Six Sigma is to statistically
  represent how a process is performed, and
  determine where defects can be eliminated. Six
  Sigma strives for just 3.4 defects per million -
  near perfection.
