                       I-PER Success Criteria

•   The instrument is expected to meet the requirements with adequate
    margins at an acceptable level of risk
•   Test plans and procedures are complete or a completion plan for any
    open item is established
•   The product verification and product validation requirements and
    plans are complete
•   The testing approach is comprehensive, and the planning test, and
    launch site and mission operations is sufficient to proceed
•   Adequate technical and programmatic margins and resources exist to
    complete the testing within budget, schedule, and risk constraints
•   Risks to success are understood and credibly assessed, and plans
    and resources exist to effectively manage them
•   Safety and mission assurance (e.g., safety, reliability, maintainability,
    quality, and EEE parts) have been adequately addressed in system,
    testing and operational designs, and any applicable S&MA products
    (e.g., PRA, system safety analysis and failure modes and effects
    analysis) have been approved
