P3.express

P3.express is an open (non-proprietary), minimalist project management methodology usable in most small, medium, and large projects. It’s not designed for micro-projects or mega-projects; for micro-projects, there’s the micro.P3.express variation, and for mega-projects, practitioners would need to heavily tailor the system before using it, or use a methodology designed for mega-projects.

P3.express is designed to be used without upfront tailoring and only recommends gradual, ongoing tailoring during its use.
