A quantitative assessment of the application of software reliability to reusable code

With the increasing utilization of reusable software, there is a definite need for software reliability analysis during the early phases of the software development life cycle. Software defects that are unobserved in one environments can manifest themselves in another, resulting in failure. If software reliability metrics are utilized in the early phases of the software development life cycle, they can identify potential problems that may be encountered when software is reused in another environment, and the cost of implementing such modifications is minimal. The benefits of such analysis is the prevention of catastrophic failures that result from the activation of unaccounted faults that are exposed when a given code is used in applications beyond its original intended environment
