Summary
Distrust and the lack of recourse are noteworthy
40% COTS software necessitates the immediate need for protective measures on behalf of the system integrator
Third-party software is a gamble; you can “increase the odds.” Frozen functionality can yield serious maintenance problems
You can assess how your system will tolerate COTS failures via testing or fault injection and then request publisher warranties and/or wrap.
Component-based software engineering will never take off without ways to warranty component quality
