Applicable to measure the reliability of aerospace software development
(B day) / B: = point to be used in determining all of the conditions with the treatment options; D = (B day,) / B = call the process parameters and the parameters of the process definition is called the same; D. = (B. Day) / B: = set of all the Conditions; D. = (B day) / B = co-ordinate the selection and some processing conditions: D. = (B day..) / B = a destination data reference. 4.13 Failure to avoid 4.13.1 Purpose: For the test phase of the metric to measure how many failure modes can be controlled to avoid the failure of critical or serious; for the design and implementation phases. The metric can know in order to avoid fatal and serious failures, under the proposed control how many failure modes. 4.13.2 for stages: design, implementation, testing stage. 4.13.3 Methods of data elements and access to the corresponding failure mode A = test case in the critical and serious failure occurred to avoid the number; B = test performed in the test case failure mode (failure cause almost) number; A1 = in the design / encoding process the number of avoidable failure mode; B1 = the number of failure modes to consider. A1, B1 of the access proposed by the developers or the demand side. Can be used to estimate the reliability growth model and used software products with similar data on the actual historical correction. 4.13.4 formula X = A / B (corresponding to the test phase) Y = A1/B1 (corresponding to the design,[link widoczny dla zalogowanych], implementation phase) to prevent incorrect operation 4.14 4.14.1 Purpose: For the test phase,[link widoczny dla zalogowanych], the metrics to measure how many there are to achieve the ability to avoid the misuse functions; the design,[link widoczny dla zalogowanych], implementation phase,[link widoczny dla zalogowanych], the measure of how much can be achieved to avoid the misuse that ability to function. 4.14.2 for stages: design, implementation and testing phase. 4.14.3 access to the data elements and methods to avoid critical and A = the number of serious failure occurs; B = in the test run (almost caused the failure) the number of test cases misuse patterns; A1: In order to avoid misuse mode to achieve the function of the number; B1 = mode number to be considered misuse. 4.14.4 formula X: A / B (corresponding to the test phase) Y: A1/B1 (corresponding to the design,[link widoczny dla zalogowanych], implementation stage)
