2.1. Distributed Development
Nobody writes software entirely in-house anymore. Outside the world of embedded systems, almost everyone relies upon libraries and frameworks written by someone else. By using them, it is possible to concentrate on the actual logic of the application while reusing the infrastructure, frameworks, and libraries written and provided by others. Doing so shortens the time needed to develop software.
