    Can designed experiments be used to learn about variations in a process?

    Paul,
    Yes, a DOE can be used to test for the effect of factors on means and the effect of factors on variation.

    Paul, think about it a minute. What would the objective of an experiment be if not to assist in determining what factors ahve what impact of an output? With an properly constructed DOEs you vary the inputs and measure the effect on outputs.
    That is one of the primary objectives of an experiment.
    It begs another question, just where are you in your learning/understanding of SS? It’s is certainly not a problem if you are new to SS or in the process of learning however the question you posed is rather strange.

    As has been noted – you can use a DOE to look for factors impacting the process mean as well as the process variation.  The post below has the details for using a design to study variation.
