The Mars Rover is an incredible reliability story.  And as you may know they have decided to permanently shut it off. A friend recently sent me this email when he saw an article on it.

Hey Adam,

The Opportunity rover was supposed to last 90 days, and instead lasted 15 years.

Is that due to remarkable engineering, or was the machine really supposed to last that long and the scientists blew their calculations as to its “lifespan”?

Mark,

I introduced my new program tool “Program Risk Effects Analysis” (PREA) at the RAMS Conference in Orlando this week.  It’s a great tool to assist in accessing if program schedule or resource should accommodate found design risk from testing or analysis.

A very personal Use Case 7

(Have you been introduced to Use Case 7? )

“Use Case 7” is a concept I am rolling out.  Use Case 7 is the way a customer may use your product in a manner that is way beyond anything you expect.

Examples:

1. Me using a power drill as a hammer. “I’m not walking all the way back in the house to get a hammer just to put a nail in!”
2. My Dad when he used to load 300lbs of firewood into the back of his Nissan Sentra. Then make us kids lay on top of it since the seats had to be folded down.  But I think that last part is more of a child services situation.
3. That wire shirt coat hanger with the leather motorcycle jacket on it, and three pairs of wet ski glove clipped to it…and you hold onto it when you bend down to pick up your shoes.
4. You when you were sixteen and had your parents car in a full drift in the mall parking lot on Saturday night (I’m projecting here), or when you owned that same car and didn’t change the oil…ever (sorry Dad)

Happy New Year! And thank you for letting us break your stuff to improve your design in 2018. This is a story of when I was NOT invited to break things but did anyway.

As a reliability guy I love seeing how stuff works.  Was recently given an opportunity to mess around and compare a new product to it’s siblings in a field I love, welding. I recently provided some input on an article release by Superiorglove about types of insulation and heat conduction. Superiorglove is a glove manufacturer that makes about every type of glove you could imagine, many are really impressive industrial applications gloves. I like how much they get into the science of it. In our discussions I used an example of how my TIG welding gloves protect against conductive and radiative types of heat transfer.  They informed me that they had a TIG welding glove line and would love if I would review four of their models.   I happily accepted because I love to weld, check out how things work and …free gloves.

I had the unbelievable pleasure of piloting a retired 1953 T-34 Air Force plane.  The plane is owned by a friend and it has recently undergone a full restoration.  A few year ago this model was grounded by the FAA due to an unusual issue.  After the investigation the fleet was cleared to fly and the root cause was ruled as “mis-use.”  Something many of use may not consider enough when creating our own products.

I have heard that “Reliability and Quality are kissing cousins” and also that “Reliability is Quality over time.”  Neither of these definitions ring true to me.  To be honest I’m a smidge offended because both of these terms diminish the value of the objective of reliability.  I would state that reliability is “The design of a device or system so that it works as intended consistently over it’s defined use-life.”  To me the key differentiator from my definition and the previous two descriptions of reliability is the word “design.”

If you finish the Design Failure Mode Effects Analysis (DFMEA) before the product is out in the field, you have made a horrible mistake. The worst DFMEA that can occur is one that is completed and filed away mid-program. A high value DFMEA is a live tool that has both inputs and directive outputs throughout the program. A tool that is interwoven into the day to day activity of the program.  The DFMEA drives actions and aids decisions both technically and in project management.  It is updated with design changes that change risk and mitigative strategies.
