Description
Attributes of software that bear on the effort needed for diagnosis of deficiencies or causes of failures, or for identification of parts to be modified.
Indicators
1. fault position recognition ratio
The ratio of number of failures where users correctly recognised the fault positions to the number of detected failures caused by the faults of the software as a consequence of the maintainer analysing the failures.
Source: ISO
Note: A higher value is preferred.
2. mean failure analysis time
Mean time needed to analyse a failure, and to discover any faults arising from this failure, and separate the positions to be repaired by the maintainer who received the failure report.
Source: ISO
Note: A lower value is preferred.
