When we are given a problem our reflex is to find answers. But it can be difficult to leave the comfort zone and to come up with creative answers. This exercise will encourage to think out of the box.
Come up with new ways of thinking.
Get the questions out you and your colleagues have in mind. Sometimes it helps to generate different & better questions.
For a given problem do generate as many questions as possible. Do not try to answer them (yet). Do not judge them (yet). Don't explain why you are asking this question.
After the brainstorming have a look at the questions you collected. When a particular question does provoke you to create new ideas and solutions, follow this path.
"We cannot solve our problems with the same thinking we used when we created them." Albert Einstein
"If you have a problem for which you have no solution, you need to ask better questions. The reason a problem exists is that it is hooked like a Siamese twin to a question we are already asking. And if we don't change our questions we will not get a new solution."
