I have always taken the expression "common sense" to mean things that are obvious to anyone except a fool. That is quite different from the expression referencing "conventional wisdom", or it's equvalent, "common thinking", which refelects the unverified assumptions that are usually based on sources less reliable than gossip. 

Common sense dictates that one would not stick a hand into the cutting area of a lawnmower, or stand on the very top of a folding ladder. Common sense is that wisdom that lawyers seem to dictate that it is not reasonable to expect their client to posess.

@Ann: The Italian writer Antonio Gramsci drew a distinction between common sense and good sense.

To Gramsci, "common sense" meant the ruling ideology of a society: the ideas that are generally accepted without much critical thought.  As such, "common sense" is not universal, but may be radically different in different times and places (according to Gramsci, mainly depending on who's in charge).

"Good sense," on the other hand, requires critical thought.

"Common sense" might contain some elements of "good sense," but they are very different things.

Dave's comment about "intuitively obvious" makes me think of how many times I've been told that a certain practice is "common sense." My response is always "common to which group?" The term implies shared values and meanings, and shared assumptions about how the world does and should work. But these are not so common In a modern complex society.

Another great article from Professor Craig.  The only part I take issue with is the claim that "the grey-box modelling approach is intuitive and obvious." First of all, our intuitions can often mislead us.  Read The Invisible Gorilla, by psychologists Chris Chabris and Dan Simons, for many instructive examples of everyday illusions.  Second, if these things were obvious, there would be no need for engineers... let along engineering professors!

On the subject of modelling the real world, take a look at Dan Meyer's blog.  Dan is a high school math teacher who gave a though-provoking TED Talk called Math Class Needs a Makeover.  Dan puts modelling at the center of his teaching.  It's an approach that can help prepare students to engage in engineering problem-solving.

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.
While risk management sounds like one activity, in order to be conducted effectively, it must be broken down into three sub-components: risk assessment, risk monitoring, and response planning.
While many larger companies are still reluctant to rely on wireless networks to transmit important information in industrial settings, there is an increasing acceptance rate of the newer, more robust wireless options that are now available.
To those who have not stepped into additive manufacturing, get involved as soon as possible. This is for the benefit of your company. When the new innovations come out, you want to be ready to take advantage of them immediately, and that takes knowledge.
Design engineers will feel like kids in a candy store with the Cypress Semiconductor BLE Pioneer Kit. The development kit for low-power sensor-based systems is full of wireless wonder and exploration.
