I’ve had a hard time identifying good industry rules of thumb for conservative controls design. So I’ve started a category on the wiki named “Rules of Thumb”.

These rules of thumb should provide inexperienced controls engineers with guidelines to a good design. For experienced engineers, I hope we will find these rules of thumbs to be informative about how other industries design their systems. We may even find that another industry’s common practices make sense for our own.

Please add whatever rules of thumb your industry uses.
