This document discusses different models of project governance for open source software projects. It describes governance as establishing roles and processes for decision making. Key governance models discussed include the benevolent dictatorship model, where a single leader has final say, and the meritocratic model, where leadership roles are earned based on contributions and respect. The document also contrasts more closed, hierarchical models like the Cathedral approach with more open, participatory models like the Bazaar. Ubuntu is presented as striving to balance control and open contribution. Effective communication of a project's governance model is important for managing contributor expectations.
