Agile is an iterative approach to project management (originated in the software development industry) that focuses on flexibility, communication and segmentation.
There are many different application methodologies of the agile philosophy (Scrum is the most popular), each of it is unique in its specific approach. But they all share a common vision and a set of core values:
Four essential values of the agile methodology:
• Individuals and interactions over processes and tools
• Working software over comprehensive documentation
• Customer collaboration over contract negotiation
An agile goal is a "higher purpose," which transcends the goals of all stakeholders. It is a goal for the entire system, not a goal just for the Product Owner, or the manager, or the CEO, or the shareholders;
Agile goals are not required to conform to a whole range of criteria, like specific, measurable, etc. A goal depends on its context. Sometimes it should be inspiring, sometimes it should be measurable;
An agile goal should not be connected to rewards or incentives. Extrinsic motivation distorts the system and causes non-linear consequences, which often defeat the purpose of the goal itself. Instead a goal should address people’s intrinsic desires
