Deciding how many PVOBs to use
Projects that use the same PVOB have access to the same set of
components. If developers on different projects need to work on some
of the same components, use one PVOB for those projects.
For example, Related projects sharing
one PVOB shows
concurrent development of two versions of the Webotrans product.
While most members of the team work on the 4.0 release in one project,
a small group works on the 4.0.1 release in a separate project. Both
projects use the same components, so they use one PVOB.
Consider using multiple PVOBs only if your projects are so large that PVOB capacity becomes an issue.
