A project manager ideally wants to work in a functional, project-based organization where he or she has complete control over the team. Although matrix organizations are highly popular nowadays, the multiple-boss structure is, of course, something that most bosses would prefer to avoid because it cuts down on their authority and forces them to work with another boss.

As such, as a project manager, I would prefer a functional group. However, what is best for the project manager is not neccessarily what is best for a team or an organization that is constituted of many teams. Matrix organizations ensure that poor decision-making by a boss can be mitigated. As such, although I personally would prefer to be a manager in a functional organization, I can see why there are more matrix organizations out there.
