Modular subsystems in a wheelhouse technology may or may not be a staple in your industry.  There are some industries where they are not a standard practice and there are industries where without them, you can’t be a competitor.  Of course there is everything in-between.

First let’s define what a modular subsystem is for this discussion.  A modular subsystem is an assembly that is designed to be integratable into multiple products.  For the automotive industry this could be a transmission.  Each car model a manufacturer makes does not have a unique transmission design.  There may be six transmission types that cover 20 car models.

I just came back from one of the best RAMS conferences I have attended (In my over 10 years of attending).  I was fortunate enough to present a paper on “Balancing Reliability Goals in the Product Development Process”.  The questions I received were great!  The higher level management of how reliability integrates into product programs is the next big advancement for our discipline.

An executive asked me how to make a “perfectly reliable product.”

I told him that program would look a lot like an embarrassing market failure that could put a company out of business.

This was not the response he was expecting.  I chose to elaborate before he just walked away.

The investment of time, dollars, and man power to create a “perfectly” reliable product would force such a compromise on all other aspects of the product and program that any type of market success would almost be impossible.  I can only think of two types of products that could benefit from an approach of creating perfect reliability. The two I am thinking of are the Mars Rover ‘Curiosity” and a nuclear power plant. The desire for “perfect reliability” would be driven by either an avoidance of massive loss of life (not just a few lives) or loss of billions of dollars by a single failure mode.

The Titanic had two sister ships, the Britannic and the Olympic. There was a woman called Violet Jessop, a nurse and a cruise liner stewardess that worked on all three. (That’s her, to the right->)

1. The Olympic crashed into a warship whilst leaving harbor but was able to make it back.
2. She was on the Titanic as it sank and is referenced in the Titanic film, a stewardess that was told to set an example to the non english speaking passengers as the ship sank. She looked after a baby on lifeboat 16 until being rescued by the Carpathia the next day.
3. It’s not known what exactly caused the sinking of the Britannic but the lifeboats hit the water too early. As the ship sank, the rear listed up and a number of the lifeboats were sucked into the propellers. Violet had to jump out of the lifeboat she was in and sustained a serious head injury, but survived.

Toyota just issued a recall of all 1993 Toyota Camrys. Tokyo-  “It’s simply time for drivers to move on.” Then added “We understand that the 1993 Camry was tremendously dependable, but, honestly, there’s just no excuse for driving a 24-year-old car at this point. You could have updated features like bluetooth and a backup camera” said Toyota spokesman Haruki Kinoshita. While Toyota is reportedly confining its recall to the 1993 Camry, it also issued a warning to owners of 1994 to 1998 models alerting them to the fact that they were really starting to push it.
I can’t take full credit for that joke.  But like most satire it is inspired by a reality. I actually just walked by this car in a parking lot a few hours ago. [Read more…]
