Engineers solve problems but we have to work within constraints - be it technological, economic, political etc. It's very rare (never in my career) that I've been given free reign to implement a "perfect" solution.

There is always, always trade offs involved in engineering. As for which trade offs are acceptable sometimes you have influence over that and sometimes it's out of your hands. Design thinking is a tool that can help but it is not a panacea.

For people that don't work in the field perhaps it's not obvious. A good friend of mine is a PHD chemist who works in research (I work as a Materials Engineer in industry) he is always winding me up about engineers doing a half-assed job. I've always thought that our interactions highlight one the key differences between science and engineering, scientists strive for perfection if you will and engineers want workable...
