Validate the integrated software configuration
The integrated software configuration must be validated to ensure that is satisfies 
the specified performance measurements. The software configuration may involve 
two or more software configuration items that must be validated to operate effi-
ciently and effectively as an integrated product. This involves engineering analysis

of the integrated software configuration, taking into account the performance 
of the specified computing environment and interfaces to external systems and 
applications. The integrated software configuration validation must establish pro-
jected operational performance measurements for data processing work loads that 
denote normal, severe, and excessive conditions. This determination must estab-
lish the data processing work load that causes the software configuration to begin 
to degrade and become unresponsive. This validation may need to utilize software 
integration and testing records and computing environment benchmarks to extrapo-
late performance measurements.
The ability of the software configuration to detect and respond to hardware fail-
ures must be validated using engineering analysis or confirmed utilizing software 
integration and testing records. The ability of the software configuration to continue 
to operate in the specified degraded modes—fail-safe, fail-secure, or fail-soft—
must be corroborated.
