The western domains of philosophy provide insight into how people think. Some act to optimise the amount of good, some follow sets of rules, while others feel the needs of the many outweigh the needs of the few.
The Agile Manifesto does not outline any specific processes, procedures, or best practices for agile. And that is intentional. The creators set out to create a philosophical mindset for work that requires a change in the way you approach and enact work.
