Don't allow your tools to inhibit creative thinking.
You are leading an improvement team. Leadership wants fast results. So, you and your team need new ideas fast. The team sits around a table and you ask your team members to shout out ideas. There’s no discussion, no bad ideas, no thought given to the feasibility of implementing those ideas—just get those ideas down on paper. You take the ideas back to your desk and figure it out, sometimes with, sometimes without, excitement.
This is probably, if not a common occurrence, one that you readily identify with. At some point in your career you undoubtedly have led and/or participated in brainstorming sessions. The method described above is a common form of brainstorming. According to Carol Knight-Wallace, this form of brainstorming has a term: popcorn brainstorming.
