Agile is not Scrum, Lean, Kanban, DevOps, Extreme Programming, or any other agile method used in modern product development. Don´t get me wrong, all of these frameworks have a reason for being. I am working as a Scrum Product Owner (PO). We are successful and I thoroughly enjoy using this method. Scrum is one way (of many) to manifest and formalize agile principles. It is not equal to Agile. Agile development is a mindset centered on principles.
