Agile frameworks. Nexus frameworks for scaling scrum

Agile is a project management philosophy that employs a set of principles and values to help software teams respond to change. Agile teams value individuals and interactions over processes and tools, working software over comprehensive documentation, customer collaboration over contract negotiation,
and responding to change over following a plan. These values were set down in the Agile Manifesto along with 12 principles behind the manifesto. An agile framework is a set of rules, processes, roles and practices that enable agile working in project management and product development. It provides a clear structure and approach to using agile methods in an organized manner.
