Confusing failure modes with failure mode causes
In response to "Narrower Focus" (January 2015, pp. 23-28): I believe the author may be confusing failure modes with failure mode causes.
The author talks of the difficulty of selecting failure modes from a nearly infinite universe. This may apply to failure mode cause, but not the selection of the failure mode itself.
In my view, the identification of the failure mode is quite straightforward. For a well-defined process step, the number of failure modes is unlikely to exceed two or three.
The potential failure mode is the manner in which the process step could potentially fail to meet the process requirements.
The identification of the failure mode can be greatly facilitated by detailing the specific requirements of the process step.
Consider the article’s example of drilling a hole. The requirements for the process step may state that the hole depth is to be 20mm +/- 0.5 mm.
There are just three potential failure modes in this case: the hole is too deep, the hole is not deep enough or the hole is not drilled.
I don’t think the statement of the failure mode should contain actions such as "drilled hole too deep." I believe that actions belong with the causes of the failure mode.
It takes the right people
In response to "The Art of Root Cause Analysis" (February 2015, p. 64): It must be noted that the five whys tool only works if the right people are in the room. If at least one person is unable to answer the question why, the team will soon become stuck.
Often, the question why is not forthcoming. This is usually from a lack of understanding or involvement by the team members and so the question remains unanswered. When this takes place, more investigative efforts and analysis are required.
Quality for the Renaissance man
In response to "Well Rounded" (February 2015, pp. 10-12): Excellent perspective on the Renaissance man aspects of quality. This one deserves a follow-up article.
Getting schooled on quality costs
In response to "Lean Learning" (February 2015, pp. 39-45): I work with universities, and this is a great article that highlights the value cost improvements can have.
