1. SITUATION
What is the background or context to the task or action at hand?
2. TASK

3. TIME
When must this happen? What is the deadline, if any?
4. PLACES / ASSETS
Where must this happen? What will be affected?
5. RESOURCES
What resources do I need?
6. COORDINATION / HELP
With whom may I have to coordinate? Who can provide the resources needed?
7. CHANGE / RISKS
Plan B. What might change and put the task at risk? What controls can I put in place to prevent this?
