Explanation
Story points are the dominant estimation unit in Agile because they measure relative effort, complexity, and uncertainty rather than calendar time. This abstraction removes the psychological pressure of time-based estimates and accounts for team-specific velocity. Teams use techniques like Planning Poker to assign story points collaboratively. Lines of code, function points, and use-case points are traditional or formal sizing methods not well-suited to Agile's lightweight, iterative planning style.
