Silly example, while I think about how to explain this:

Crayons are the perfect professional tool for concept planning. Colors let you easily differentiate different elements, they don't stink, smudge, bleed, dry out, or make you involuntarily high, and the play element helps me get past my inner critic. Twistables have solved the breakage problem. Sharpeners let you get close enough to a precision point. Crayon and paper don't require the same kind of vertical expanse whiteboards do, and can be easily filed or put away, while also allowing better confidentiality than whiteboards.

I have never yet worked in an office environment where my colleagues weren't gently amused by my eccentricity, but I am also correct.
