Nodal Program Risks

• Program risks to be prioritized by temporal order
  as they pertain to next major market deliverable
• October market trials
• Subsequent functional deliveries for MP testing
• General programmatic risks, proposed mitigations
  and impact assessments
• Included in daily PMO discussions
• Escalated to marketplace when needed
• For example
• CMMs delivery status would have low impact to
  current program deliverables
• Issues related to Web Services would have
  relatively high impact
