The History of Reliability

The History of Reliability

Adam / August 22, 2017

 

If you had to section the history of reliability into only two periods I believe the dividing point would be around 1950.  The first section, stone age to 1950, the “Robust” era; 1950 to today,  the “Margin” era.   In the Robust era, reliability concerns were addressed by creating a design that was orders of magnitude stronger than required, “over-engineered”.  This protected against the variability of fabrication, use, and environment.  If it was made sloppily with low tolerances, it still worked;  Used for an unintended purpose, still worked; Left out in the snow, dropped in the river, run over…

An Old Approach That’s New Again

An Old Approach That’s New Again

Adam / July 12, 2017

The original windmills of Europe are feats of engineering.  I was able to get inside of a few in Holland and see all the mechanisms that have been operating for hundreds of years.  I was lucky that the wind was strong and the windmills had their sails out the days I was visiting.  A few were grinding flax seed and

others designed to pump water from a low basin to a high basin to control basin water levels. Being inside of the windmill was like being an insect inside of a…

I was in a meeting recently with a customer team.  It was on-site with 12 people ranging from mid-level engineers to upper management.  Someone defended me earlier in the meeting by saying “Well, he did write a book on it!”  Which was nice and kinda cool to hear someone say.  But this lead to a later comeback by a crusty, principle engineer, 40 years under his belt, boat captain from Jaws kind of guy.   “If we can buy your book then why do we need you?”

I took a moment.  I knew that not responding wasn’t what I wanted…

What do these three products have in common?

What do these three products have in common?

Bulletproof!

It is a very conscious decision to have Reliability be a part of your products brand.

What conversations with marketing and the leadership has occurred for your next product development program?  Was there a conscious decision to place your product in a certain range of reliability?

Too many times it’s a discussion that happens as the product is reaching it’s Beta stage of development, “Let’s measure it’s reliability and see where it’s at and if we need to improve it”.  You can measure reliability that late in the game but you have little opportunity to change it.  So what…

They must have done HALT because their customer did too.

I recently came across  working Nintendo “Game Boy” that looked like it had been through some seriously hard times.

This Gameboy that survived a barracks bombing during the Gulf War and currently resides at the Nintendo World Store in NYC. As is evident by the Tetris screen, it still works! Nintendo placed it in their showroom to demonstrate the level of quality they put into their products. To create a product of this caliber you would have to have executed a reliability program during design that took the product far…

A game changer for reliability of bearings

A game changer for reliability of bearings

Adam / May 21, 2015

One of the largest vulnerabilities for bearing reliability is loss of grease. Any reliability prediction for bearings is assuming a specific rate of breakdown of grease and/or a followed maintenance schedule that ensures grease quality. But regardless of what is assumed it is a huge wildcard in the life of a bering dependent system. This isn’t just a concern for mechanical engineers. What’s the number one killer for electrical systems based on wear out predictions?…… Bearing life! When the bearings in the cooling fan begin to fail and air flow drops the electrical components run hotter then intended. That…

Connecting HALT to Program Goals and Estimating ROI

Connecting HALT to Program Goals and Estimating ROI

Adam / May 13, 2015

This video is a webinar done jointly with Qualmark. The material covers how to connect HALT testing to program goals and finding the ROI of doing HALT in the product development process. It is intended to assist engineers and technical managers with communicating the qualitative and quantitative benefits of HALT to the business unit.
