So, the next time you're forming a team of "creative" people, don't skip accounting in your sweep. You might just find you get what you need from unexpected places.
Our modern culture has become very intangible. We have more physical things, but we also have more intangible elements of our lives. We can own land in a virtual world, "Second Life", and expect an exchange of virtual or real currency for its sale. While this is amazing, we are still physical human beings and it helps to get physical with our ideation. We encourage sketching / scribbling / drawing out ideas, whenever possible. Not because we are artists and should be using pencils, but because getting someone to see an intangible idea in the light you see it often requires an act of making it tangible.
This is common practice in design firms, ad agencies and perhaps other entities "paid to be creative." We encourage it with everyone. Here's a simple thought exercise with the word "innovation." Imagine asking 100 people to draw a picture of what they think that word means. How many different interpretations would you get? My guess is 111, because some bloke will give extra answers.
Now, the next time someone in an "ideation" session says out loud to the group, this has to be "innovative." Stop and ask the room to draw what that means to them individually. You'll find more sketching to show ideas in your next ideation session.
That's two of the five. Ask us about the other three.
