| Summary: | Safety-Critical Systems (SCS) perform an
important and influential role in our daily activity, but any faults
during their operation could result in loss of life, human injury,
environmental damage or major financial loss. SCS systems
deploy in many important filed that we use daily, such as
transportation, medical, space, and nuclear systems. According to
several studies, more than 59% of SCS failures could be avoided
by improving performance during the development processes.
Therefore, this paper discusses how to reduce the failure cause of
SCS systems by enhancing the reliability assessment of
development processes using PM-ISD Traceability Metrics. PM�ISD is a measurement framework that contains several metrics
used to track or forecast development processes. The PM-ISD
Traceability Metrics tracked the actual results of the oil and gas
development processes shown a failure tolerance rate of 99.27%
and a reliability rate of 98.3% for tasks that met the standards.
For tracking with time-weighted terminate, the fault tolerance
rate can be increased to 99.88% and the reliability rate can be
increased to 99.5% at the completion stage. PM-ISD is a suitable
measurement framework for developing SCS as it helps to track
the achievement of standards, which is reflected in minimizing
errors during the development stages.
