Conclusions

My experiences indicate that it is possible to increase reuse with an increased number of libraries, and that many of the libraries need to be domain specific. To successfully build domain specific libraries, consideration of the following increases the chances for success:

• Know your business objectives
• Understand reuse principles
• Do a domain analysis
• Avoid leading edge technology areas or those with a high rate of technical change
• Control the risks associated with evolving technology (e.g., language changes).
