     Can anyone tell me what tools – other than QFD and standard DMAIC (FMEA…etc) can be used for DFSS.
    The DFSS method doesn’t seem to be robust enough.

    DFSS also includes taguchi and tools for tolerance analysis both for linear as well as non linear tolerencing. It also has top level scorecards for the control phase.

    Use “DMADV” instead of “DMAIC”,regards.

    As someone already pointed out, the DMAIC process isn’t used within DFSS, although many of the tools are.
    Like DMAIC, there are a LOT of tools avialble, and not every project will use every tool.  Some key tools that are different from DMAIC:

    Initially, there will likely be a MGPP which frames the project as part of a larger program (DFSS is, after all, about changing the world, and that’s not something you do in a week).
    In Measure, there are a variety of VOC tools used to collect input to the QFD.  The QFD itself helps you understand the measures, and may also be used to deploy the measures into the functions.
    In any case, some sort of functional decomposition will probably be done, whether through QFD or not depends on the project.
    In Explore (or Analyze depending on  the particular sect of DFSS you adhere to), a Pugh matrix will likely be used to help select among design alternatives.
    Triz or other techniques are often used to help synthesize design concepts.
    A DFSS scorecard will be created which will help guide the later stages of the project.
    Almost all of these might be applicable in a DMAIC project, although that is fairly unusual.
    Hope this gives you something to start with.
