    When does determining the nature of the transfer function (linear, quadratic, etc) for the process become necessary?  How is it determined?  How is it interpreted?  How does this information fit within the DMAIC format?  Thanks for your time.

    I’m a MBB teaching DFSS for product development and in my training material I have dedicated many slides about “transfer functions” with examples. Because I don’t know how to post this material in this web-site, if you send me your e-mail I ‘ll send some material concerning this subject.

    utah,
    While you and the others are waiting for the magical slides on transfer functions to come your way, consider that this concept and its understanding is not a new one.  The development of a “transfer function” or least-square model of the process using Response Surface Methods have been with us for over 30 years.  One should consider developing a process model beginning in the Analysis phase by identifying candidate inputs to evaluate.  If you can use Design of Experiments with the process, then using a special set of DOEs will allow you to define a linear or quadratic model from the experimental data using conventional linear and/or non-linear regression.  If your process is in the vicinity of optimal, then your data will reveal curvature in the model providing you with a quadratic model.  If your process is further away from optimal, then your data will reveal little significant curvature in the model, and provide a linear model.  You could search the internet or your reference for non-linear regression, Response Surface Methods, and Design of Experiments for additional detail.
    Happy Hunting!

    Pier Giorgio .
    This is regarding one of the questions asked in isixsigma for transfer function in which you have mentioned that you will sent some slides which explain about transfer function in detail.
    Would highly appreciate if you can the same to me also for my benefit.
    my email is is [email protected]
