The document discusses the Agile methodology for project management. It began in 2001 with the Manifesto for Agile Software Development. Agile is a mindset and way of working together to deliver value to customers through principles like welcoming changing requirements, frequent delivery of working software in small batches, collaboration between business and development teams, and responding to change. Common Agile methods in use today include Scrum, Kanban, XP (eXtreme Programming) and Lean. The document emphasizes that Agile is not just for software but can be applied to any type of work.
