Discussion One of "Statistical Engineering and Variation Reduction"

Summary: In this discussion of the article "Statistical Engineering and Variation Reduction" by Stefan H. Steiner and R. Jock MacKay (Quality Engineering, Volume 26, Issue 1, pp. 44-60), quality engineering expert Roger Hoerl congratulates the authors on an excellent paper that, in his opinion, makes a significant contribution to the development of statistical engineering into a formal discipline in its own right. The authors provide several practical suggestions for addressing real problems that, if followed, will provide tangible results to practitioners. This discussion first reinforces some important points made by the authors and then offers some ideas as to how this work on statistical engineering might be taken to the next level.
