At this stage, it's also important to ensure that you look at the issue from a variety of perspectives. If you commit yourself too early, you can end up with a problem statement that's really a solution instead. For example, consider this problem statement: "We have to find a way of disciplining of people who do substandard work." This doesn't allow you the opportunity of discovering the real reasons for under-performance. The CATWOE checklist provides a powerful reminder to look at many elements that may contribute to the problem, and to expand your thinking around it.
