There are five basic questions worth asking yourself when setting out to tackle a problem.
They are as follows:
1. Do I understand this problem and its root causes?
2. Is it a big problem?
3. Is it an important problem?
4. Is it a wicked problem?
5. Is it a real problem?
Step one is self-explanatory, although a lot of people (in health policy and politics and beyond) do tend to skip it.
