Harmony. The members of any good design team should fit together like fingers in a glove: They need not lose their individual identities to work well together.
Inventiveness. Engineers are as creative as inventors. Engineers just call their inventions designs.
Judgment. Not all aspects of engineering can be quantified. Among them is judgment. This comes with experience, and it enables an engineer to make the right choice when there are no easy numbers to serve as guides.
Know-How. Technical skill, also known as know-how, is a wonder to behold, whether in analysis or design.
Lessons Learned. The old saying, "Fool me once, shame on you; fool me twice, shame on me," applies to things made by people as well as to the people themselves.
Mind’s Eye. This term has been used frequently by engineers to refer to their nonverbal visualization of concepts and designs. James Nasmyth (1808-1890), the Scottish engineer who invented the steam hammer, wrote at the time of its conception, when he sketched it out in his notebook, of "having it all clearly before me in my mind's eye."
Neatness. Neatness always counts. A cluttered design, like a messy desk, can give an impression of disorganization. It may be a false accusation, but why risk it?
Over-design. What overeating does to a person, over-designing does to a product.
Prototype. Nothing can be more beautiful to a designer than an ugly prototype that works.
