Four steps to a first action plan

Answer six questions about your organisation, including your use of cloud services.
2. Risks
Review about ten typical risks pre-selected from a public catalogue. Keep them, drop them or add your own.
3. Now and after
Rate each risk. Mark each measure once: in place, add to my plan, or later.
4. Results
Read your summary and top five actions, each with a person responsible and rough effort. Compare before and after risk maps, check the confidence figure and assumptions, then download Excel and your study file.
