To assign story points, Developers often use a consistent scale, like the Fibonacci sequence (1, 2, 3, 5, 8, 13, …), where each number represents a relative size. This scale helps in providing a structured yet flexible approach to estimating the complexity and effort required for tasks. By using a sequence where the numbers progressively increase, teams can better distinguish between smaller and larger tasks, aiding in more accurate estimations.
Over time, as the team completes more work, they better understand what each point Value means. This historical data and experience help streamline future estimation efforts. The familiarity with the scale and continuous learning from past projects enable teams to refine their estimation process, making it quicker and more reliable, though never entirely accurate.
