I should probably point out the strategy we are trying to implement:
time based releases rather than feature based.
An excellent source on this issue is Martin Michlmayr's PhD thesis in
which he argues for time based releases:
Quality Improvement in Volunteer Free and Open Source Software
Projects: Exploring the Impact of Release Management
It is extremely relevant to us. He surveys many similar projects like
GCC, GNOME, Debian and others.
>From the abstract:
This dissertation explores why, and under which circumstances,
the time based release strategy is a viable alternative to
feature-driven development and discusses factors that influence
a successful implementation of this release strategy. It is
argued that this release strategy acts as a coordination
mechanism in large volunteer projects that are geographically
dispersed. The time based release strategy allows a more
controlled development and release process in projects which
have little control of their contributors and therefore
contributes to the quality of the output.
