Thank You For Letting Apex Ridge Break Your Stuff in 2018
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.
Your organization sucks at reliability if (#2) … it loves firefighters so much it forgets to hate fires.
Before you go on, please have a look at British comedian John Oliver’s video on infrastructure – https://www.youtube.com/watch?v=Wpzvaqypav8.
OK, if you are reading this and still haven’t watched the video … please go back and try again. You can do it.
If you haven’t watched the video by now, then I concede defeat. In short, the video is a humorous take on the state of US infrastructure. Particularly bridges. Bridges have been collapsing with alarming frequency in recent years. And after much political wrangling there is still no plan to pay for fixing crumbling columns, spans and struts. It is not as if the federal and state governments don’t know how bad things are (again … watch the video).
Oliver proposes a perhaps novel reason for all of this. [Read more…]
Your organization sucks at reliability if (#1) … it could be on ‘that’ Fatboy Slim album cover.
Alright … this needs a lot of context. English electronic music artist ‘Fatboy Slim’ released his ‘You’ve come a Long Way, Baby’ album in 1998. Its cover art was a photograph of an attendee at the 1983 ‘Fat People’s Festival’ in Danville, Virginia. And perhaps due to its ‘heritage,’ the album’s cover was changed to an image of a bookshelf for North American listeners. But the rest of the world got to bask in its magnificence.
So what is particular about this photograph? The subject is a larger than average human (as you would expect noting where it was taken). And he is wearing a shirt emblazoned:
I’m #1 so why try harder?
I am not writing this as a commentary on human value versus instinctive stereotypes. Far from it. There are plenty of people who are ‘better than all others at something’ that do not have sleek chiseled physiques. [Read more…]
Why?
When something is working it is easy to just keep going forward. But how do you know things will keep chugging along? Is it worth stopping and asking “Why is this going well?”
I like lock picking “Lock Sport.” Of course I do. It’s a mechanical puzzle. It can also make you look like James Bond when someone forget’s their keys. I continue to challenge myself by getting progressively harder and harder locks. Throughout the years lock designs have come up with some great features to resist being picked. But there is still not one out there that is “pick proof”, so there is always a next level. I would say I am a mid-intermediate in the world of Lock Sport. So any lock that actually has good picking defenses can give me a good struggle.
TIG review
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.
Engineering Reports Need to Be Like Bad Movies – Give The Ending Away At The Start
I am frequently asked to review engineering reports and documents. And I am continually baffled with how many engineers want to ‘take their reader on a journey’ as opposed to getting to the main point. These engineers write documents where you have to read every single word to work out what they are trying to say. But having a final reveal is never a good thing in any technical document.

Flying Back in Time
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.
Millennials and Management: It Is Your Fault They Don’t Stay at Your Company
I was presenting at the Aerospace Conference earlier this year, where something astounding happened. I was talking to the audience about ‘organizational culture’ and my experiences working with a small satellite manufacturer to help them improve their product’s reliability.
At the end of my talk, I was asked the following questions (which I have done my best to remember verbatim):
How do you accommodate the young engineers of today, who will only stay at one organization for a couple of years before moving on? Research has shown they typically leave within three years – so why should we invest time and effort into them?
If you are a team leader or manager that is searching for the answer to this question, I have some potentially bad news for you:
It is not them … it is you. [Read more…]
Reliabilty Culture in Stuttgart
I just returned from a great conference in Stuttgart called “Reliability Days.” I presented on some new concepts and techniques with regard to assessing and improving reliability culture in the product development process. Enjoy the presentation.

The Russian Concorde … and why you haven’t heard of it
I was recently talking with my colleague Fred Schenkelberg from FMS Reliability (this conversation can be heard here), about a plane that he had never heard of. Most of the world hasn’t heard of it. And there is a reason you probably haven’t either. The plane in question is a case study on how to design something to fail.
Stop calling us “Kissing Cousins”
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.”
Use The Force in Your Favor
We all would like a clear path to achieve what we need. But we all know that it’s not the clear sections of the path where we spend most of our time. In product development many of these events we label as “obstacles” are in fact other individuals.
If these team members are noted as being strong enough to be considered an obstacle that means they have strength. This is a good quality in a team member. If we were to get ourselves headed in “generally” the same direction a lot of progress could be made very quickly.
Small Satellites, Emerging Technology and Big Opportunities (part seven of seven) – Ok … now what?
There is no question that standardizing processes, techniques and best practices has contributed greatly to technological evolution. Just writing down or passing on what has worked well in the past helps anyone’s learning process. But there are many problems associated with this approach when blind obedience kills critical thinking.
The Good DFMEA The Bad DFMEA and Ugly outcomes
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.
