Integrating Hardware and Software
Reliability Analysis
Software and hardware reliabilities
are often assessed separately due to differing processes. If a
whole-system view is taken at all, it is usually a product of
separate software and hardware analyses. However, this approach
ignores interactions and dependencies between the hardware and
software and can introduce error into the system assessment. This
presentation shows advantages of an integrated approach over
traditional approaches and outlines a process for accomplishing an
integrated system reliability assessment.
When assessing a system’s
reliability, taking an approach that integrates hardware and
software reliability assessments can be more representative of the
system’s true capabilities than an approach assessing software and
hardware separately. Interactions between the software and hardware
can be better captured, reducing error and providing a more accurate
assessment of the system’s operational performance.
Key Words: Software Reliability, Hardware Reliability,
System Reliability, Integrated Approach, Dependency
