This is a tricky one, because “let’s choose not to have that problem” can •also• be one of the most powerful thoughts in engineering.
For it to be so, three things are •strictly• necessary:
1. A good understanding of the problem, including the other person’s (a) goals, (b) constraints, and (c) tradeoffs.
2. An understanding of the problem’s history, including options they’ve already considered.
3. A social relationship with the other person where such advice is appropriate and welcome.
