             8.4  COMPARISON WITH CURRENT SIX SIGMA TOOLS

      ArethereanybenefitsinincorporatingtheCRTandFRTintotheSixSigmacurriculum,
      and if so, how? As the scope of the CRT and FRT overlaps with some of the existing Six
      Sigma tools -- root cause analysis (RCA), the cause-and-effect (C&E) matrix, FMEA,
      QFD, and design of experiments (DOE) -- is it better to stick to one tool or to have
      alternative tools for people to choose? In my view it is better to stick to one and use it
      well. Using a common platform can only improve communication and effectiveness.
      With the proliferation of tools with overlapping uses, deciding when to use what is a
      serious problem for Black Belts.
        Although some of these tools were created as a ‘complete system’ with their own
      purposes (e.g. FMEA and RCA), they have been adopted into Six Sigma as just a
      component in the DMAIC process. Thus, the following comparison is confined to the
      usage of tools within the Six Sigma environment.
