Complexity (Useability)

Thought-provoking article.  I've found that useability (and mis-use) is the area that also deserves special attention when designing certain types of devices.  Identifying the appropriate use cases for products tends to be straight-forward.  However, having the creativity to predict all of the mis-use cases that could possibly occur is challenging and takes an extra amount of time and mental imagination to really get it right up-front.

I think the statement, "Ironically, complexity is often added to a system to reduce common-mode failures" is true no matter what level of design you are at - from simple circuits to intricate systems - but at the system level the interactive nature of the subsystems can indeed cause some unexpected issues that are much more predictable in less complex designs. Interesting article with much food for thought...

Kevin, it makes perfect sense that complex systems require new forms of management as they become more complex -- especially in the realm of avoiding catostrophic failures. Nice review.

A Frost & Sullivan study finds that increased cyber attacks are prompting a flurry of innovative protection tools.
Devices and interconnected systems are finding a foothold not only in our homes but in mainstream organizations. Here are three tips to mitigate the risk.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
