At XP 2004 I presented a paper on a way of scaling Continuous Integration. Here is the abstract:
Continuous Integration (CI) is a well-established practice which allows us as developers to experience fewer development conflicts and achieve rapid feedback on progress. CI by itself though becomes hard to scale as projects get large or have independent deliverables. Enterprise Continuous Integration (ECI) is an extension to CI that helps us regain the benefits of CI when working with separately developed, yet interdependent modules. We show how to develop an ECI process based upon binary dependencies, giving examples using existing .NET tools.
The full paper is available here.
Example implementations that were used during the presentation of this paper are available here.
