Problem Statements (Claim first)
If the template isn't working for you, try starting with these questions. Take your answers to these question and put them into fairy-tale order (Status Quo, Destabilizing Moment, Consequences, Resolution). Then, try turning those answers into a form that will match the problem statement template.
Where the Project Management and Requirements work with Problem Statements usually diverge is at the Problem Decomposition stage.  Once a problem has been identified, the business analyst will work with the client to decompose it into smaller distinct elements. These may be new dependent problems that are smaller but separate issues that cause the problem(s) at higher levels; or the components of a problem such as who is involved in the process, the systems used, the business units or system with input to process or who take output from it, and other characteristics.
