According to the AMSAA website, “Reliability growth tracking is an area of reliability growth that provides management the opportunity to gauge the progress of the reliability effort for a system. The choice of the correct model to use is dependent on the management strategy for incorporating corrective actions in the system. However, it is important to note that the AMSAA/Crow test-fix-test model does not assume that all failures in the data set receive a corrective action. Based on the management strategy some failures may receive a corrective action and some may not.
The purpose of the AMSAA RGTMC is to assess the reliability improvement (within a single test phase) of a system during development, for which usage is measured on a continuous scale. The model may be utilized if individual failure times are known, or if failure times are only known to an interval (grouped data). The benefits associated with the AMSAA RGTMC include:
- the model can gauge demonstrated reliability versus planned reliability;
- the model can provide statistical point estimates and confidence intervals for MTBF and growth rate; and
- the model allows for statistical goodness-of-fit testing.
