There is increasing pressure in my org to adopt a project management framework. I want to understand the different frameworks and the problems they're meant to solve, so I can more meaningfully contribute to the discussion. The problem is, the materials online never seem to explain that question I'm interested in - what problem is this framework trying to solve, how does it do it better than other frameworks, what are the tradeoffs in adopting this framework. You just get a giant flowchart and vague assertions that seem designed to imply this framework is universally wonderful for all possible problems.
Is there any resource that looks past the marketing fluff and explains what specific problems each project management framework is designed to solve, the tradeoffs in adopting the framework, and in what scenarios you might want to use one over the other?
