1) A problem is defined as any situation where there is a gap between the current state and a desired state. Problems can be complex with many interacting parts, or simple.
2) Recognizing that a problem exists is the first step, even if the cause is unknown. We must also have the power and authority to implement solutions.
3) Complex problems may need to be broken down and redefined from multiple perspectives to fully understand the problem. The right problem must be solved.
