Lessons Learned – Test as You Fly, Fly as You Test, and Demonstrate Margin (1998)
Year: 2002
Abstract: Abstract:
Mars Polar Lander had deficiencies in compliance with the principle of "test-as-you-fly," which requires that ground tests and simulations accurately reflect the planned mission profile, plus margin.
Enforce the system-level test principle of "test as you fly, and fly as you test," and carefully assess any planned violations. When using simulations for system-level verification, validate models and include sufficient parametric variations in the simulations to ensure that adequate margins exist.
