Your risk and mitigation list
you should cover:
1) Some NFRs or SLAs which is some what difficult to meet and how you are tackling it.
2) Some Functional requirement- like integration with external system and which needs to adhere to the SLA and there could be chances that SLA can't be met in those cases how you are tackling it.
You can go beyond 3 risks and mitigation list also. I provided 7 in my finished assignment.
