Scrum is the most widely used and popular agile framework.1 The term agile describes a specific set of foundational principles and values for organizing and managing complex work.
The term Scrum comes from a 1986 Harvard Business Review article in which authors Hirotaka Takeuchi and Ikujiro Nonaka made an analogy comparing high-performing, cross-functional teams to the scrum formation used by rugby teams.
Though it has its roots in software development, today Scrum refers to a lightweight framework that is used in every industry to deliver complex, innovative products and services that truly delight customers. It is simple to understand, but difficult to master.
Agile principles and values foster the mindset and skills businesses need in order to succeed in an uncertain and turbulent environment. The term agile was first used in the Manifesto for Agile Software Development (Agile Manifesto) back in 2001.
The main tenets of the Agile Manifesto are:
Individuals and interactions over processes and tools
Working [products] over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan
That is, while there is value in the items on the right,
we value the items on the left more.
Scrum fulfils the vision of the Agile Manifesto by helping individuals and businesses organize their work to maximize collaboration, minimize red tape, deliver frequently, and create multiple opportunities to inspect and adapt.
The difference between agile and Scrum is that agile refers to a set of principles and values shared by several methodologies, processes and practices; Scrum is one of several agile frameworks--and is the most popular.
