The comprehensive guide to software re-engineering and reuse.[Despite the fact that most software uses the same blocks of code over and over again, almost all software is built from the ground up. Just starting to catch on is the idea that these blocks of code can be used as standard components in creating new applications. However, this "assembly line" mentality is foreign to most software developers. Practical Software Reuse shows developers how to take advantage of existing codes to build commercial software faster and cheaper, covering reuse operations, competitive benchmarking, transitioning to the reuse process, utilizing "off-the-shelf" software, and more.
