Identify some people in the Organization who you feel are highly creative. Try to hear them speak as much as possible, or read papers that they have written, in order to better understand the thinking process they use in generating new ideas and approaches. If possible, ask them about how they generated some of their more creative ideas, and see if there are any tactics that you could adopt.
Check the TV listings to watch and listen to creative people (e.g. scientists, writers) talk about how they approach their work. Try to understand the many different ways of being creative.
