Contract column to indicate agreement between the creator of the noise and the receiver. Blue highlighted X indicates a key noise that the team are concerned about based on history or engineering judgement. Key noise rows are indicated by a larger font. Error State Interactions Noises that could possibly cause the error state. X indicates a strong interaction, 0 indicates a weak interaction NFMS Strategy that the team have adopted (X) or are investigating (I) to become more robust to the noise. Description records basic details Test Coverage Required to Test indicates which error states (letter correspond to error states) should be tested for this noise, base on the Error State Interactions. Plan Shortfall indicates which error states no test is planned for that includes this noise. DV Status indicates which error states have been tested for against this noise, with a pass results. Overall Shortfall is the combination of the plan shortfall, and tests which have not yet been completed. Test Coverage Shows the composite of the two Test Interaction matrices. It indicates for each noise, and each test, which error states will be tested for. This provides a measure of the efficiency of the test - a test with very few letters is inefficient, while a test with a column full of letters is very efficient. Resource should be focused on the efficient tests. Test Interactions Records which test can detect which Error States and check for Ideal function Test Interactions Records which test includes the noise Not shown on the printed version ็จณๅฅๆ€งไธŽๅฏ้ ๆ€งๆŸฅๆฃ€่กจ็จณๅฅๆ€งไธŽๅฏ้ ๆ€งๆŸฅๆฃ€่กจ

Contract column to indicate agreement between the creator of the noise and the receiver. Blue highlighted X indicates a key noise that the team are concerned about based on history or engineering judgement. Key noise rows are indicated by a larger font. Error State Interactions Noises that could possibly cause the error state. X indicates a strong interaction, 0 indicates a weak interaction NFMS Strategy that the team have adopted (X) or are investigating (I) to become more robust to the noise. Description records basic details Test Coverage Required to Test indicates which error states (letter correspond to error states) should be tested for this noise, base on the Error State Interactions. Plan Shortfall indicates which error states no test is planned for that includes this noise. DV Status indicates which error states have been tested for against this noise, with a pass results. Overall Shortfall is the combination of the plan shortfall, and tests which have not yet been completed. Test Coverage Shows the composite of the two Test Interaction matrices. It indicates for each noise, and each test, which error states will be tested for. This provides a measure of the efficiency of the test - a test with very few letters is inefficient, while a test with a column full of letters is very efficient. Resource should be focused on the efficient tests.
