COCOMO II Cost Drivers
Required Software Reliability [RELY]
This is a measure of the extent to which the software must perform its intended function over a period of time. If the effect of a software failure is only a slight inconvenience then RELY is set very low. If a failure would risk human life then RELY is set very high.
|Low, easily recoverable losses
|Moderate, easily recoverable losses
|High financial loss
|Risk to human life
This cost driver can be influenced by the requirement to develop software for reusability. See the description for RUSE.
