Derek Powazek wrote a great post entitled The Art of No which suggests we ask why instead of saying no:

“When you say ‘why’ instead of ‘no’, you open a design conversation that can help inform both sides. You also make it more likely that the boss will ask you questions in the future, which is all designers want. We’d all much rather hear, ‘Why did you make this design choice?’ than ‘I don’t like this – change it.’”

Derek’s piece focused on web designers, but it applies to anyone working in a professional setting. Asking why (or other questions) improves communications, enhances collaboration and makes learning possible.
