## TL;DR

Scrum is the most popular Agile framework, defined by the Scrum Guide (Ken Schwaber and Jeff Sutherland, latest 2020). It prescribes three roles, five events, and three artifacts within fixed-length Sprints. Scrum is lightweight but hard to master — it requires cultural shift, not just process adoption.

## Core Explanation

Roles: Product Owner (WHAT to build), Scrum Master (HOW to Scrum), Developers (build it). Events: Sprint Planning, Daily Scrum (15 min), Sprint Review, Sprint Retrospective. Artifacts: Product Backlog (ordered todo), Sprint Backlog (sprint plan), Increment (done work). Definition of Done: shared quality standard for completed work.
