Are you new to Scrum development or curious about how to accurately estimate your project backlog? One of the critical concepts to understand when using Scrum is the concept of story points. By using story points, Scrum teams can estimate their upcoming work more efficiently and effectively. In this article, we’ll provide a comprehensive guide to what story points are, how to use them properly, and the benefits they provide to Scrum teams.
What are Story Points?
At its core, a story point is a way to estimate the effort required to complete a specific task or user story in Scrum. It’s a unit of measure that Scrum teams use to determine how much work a task will require. A story point is an arbitrary value that isn’t linked to any specific unit of time or measured by something like hours, days, or weeks.
Why Use Story Points?
Scrum teams use story points because they’re a more accurate and consistent way to estimate work. Story points allow teams to take into account the complexity and effort required to complete a specific task, and they are more indicative of the team’s velocity than time-based estimates. By estimating work in story points, Scrum teams can help ensure that they complete the desired amount of work within their sprints.
How to Use Story Points
Story points are assigned to user stories or tasks in Scrum during a team’s sprint planning session. During this meeting, the team collaborates to agree on the effort required to complete each task. The team can reference past experiences, consult with subject matter experts, or use any other method they see fit to estimate the effort required. Once the team has agreed on the story point value for a task, they can add it to their product backlog.
The Fibonacci Sequence and Story Points
Story points are often assigned using the Fibonacci sequence. The sequence starts with 0 and 1, and the following values are the sum of the previous two: 0, 1, 1, 2, 3, 5, 8, 13, 21, etc. By using Fibonacci numbers, teams can account for the uncertainty and complexity inherent in many tasks.
Benefits of Using Story Points
Using story points can provide several benefits to Scrum teams. First, story points allow teams to estimate work more accurately and consistently, which can help them plan and meet their sprint goals more effectively. Second, story points help teams avoid the pressure to commit to time-based estimates that can lead to detrimental behaviors like rush work or task half-completion. Finally, using story points can help teams identify areas where they need to improve their processes or skills.
Story Points and Velocity
Velocity is a metric that Scrum teams use to measure the amount of work they can complete in a single sprint. By estimating work in story points, teams can use that value to calculate their velocity for each sprint. Measuring velocity allows teams to understand their capacity for work and helps them plan and manage their sprints more effectively.
