Daily build and feature development in large distributed projects

Daily build is a software development paradigm that originated in the PC industry to get control of the development process, while still allowing the focus on end user requirements and code. The PC industry used daily build to avoid chaos in increasingly larger applications in an environment without a strong development process. Ericsson Radio Systems has chosen to implement daily build to increase the focus on end user requirements and code, but from a different starting point with a traditionally strong development process. The authors discuss their experiences with daily build and feature oriented development in this context. They also relate their experience to the concept of extreme programming, arguing that their ideas can help extend the applicability of extreme programming beyond small co-located projects.
