Paul, that’s a really solid article.

I was actually debating the value of developing multiple concepts with a couple of designers the other day and I definitely was taking the same position you are — it sounds good to deliver multiple versions but as a designer you should know which is actually the best design and (without being arrogant) it’s counter-productive to provide examples that you ultimately believe are below par.

A number of the other points are really strong as well. Providing written material explaining your thinking, wireframing, understanding users… these are the crux of a solid relationship.
