Gather Your Inputs
First, identify your team's capacity, which is the total number of hours available for work during the sprint. Then, gather your team's historical velocity, which is the average number of story points completed during previous sprints. Finally, make a list of the stories you want to include in the sprint, along with their estimated story points.
Calculate the Sprint Velocity
The formula to calculate sprint velocity is: Sprint Velocity = (Historical Velocity x Team Capacity) / Total Available Hours. For example, if your team's historical velocity is 20 story points per sprint, your team capacity is 80 hours per week, and there are 40 hours available for work during the sprint, the sprint velocity would be: Sprint Velocity = (20 x 80) / 40 = 40 story points.
Calculate the Story Point Estimates
To calculate the story point estimates, you need to estimate the complexity of each story. You can use the Fibonacci sequence (0, 1/2, 1, 2, 3, 5, 8, 13, etc.) to estimate the story points. For example, if you have a story that you estimate will take 2 days to complete, you might assign it 2 story points. If you have a story that you estimate will take 1 day to complete, you might assign it 1 story point.
Prioritize the Stories
Once you have estimated the story points for each story, prioritize them based on their business value and complexity. You can use the MoSCoW method (Must-Haves, Should-Haves, Could-Haves, Won't-Haves) to prioritize the stories.
Calculate the Sprint Forecast
To calculate the sprint forecast, add up the story points for the top-priority stories until you reach the sprint velocity. For example, if your sprint velocity is 40 story points and you have the following stories: Story A (10 story points), Story B (10 story points), Story C (5 story points), and Story D (15 story points), your sprint forecast would include Story A, Story B, and Story C, for a total of 25 story points.
Use a Calculator for Convenience
While calculating sprint velocity and story point estimates manually can be helpful for understanding the underlying formula, it can be time-consuming and prone to errors. Consider using a story point estimate calculator to streamline the process and improve accuracy. These calculators can also help you to track your team's progress over time and identify areas for improvement.
Introduction to Sprint Velocity and Story Point Estimates
Calculating sprint velocity and story point estimates is essential for agile teams to plan and track their work. In this guide, we will walk you through the steps to calculate these values manually. We will cover the formula, a worked example, common pitfalls to avoid, and when to use a calculator for convenience.
What You Need to Know Before You Start
Before you start, you should have a basic understanding of agile principles, sprint planning, and story point estimation. You should also have the following information available: team capacity, historical velocity, and a list of stories with their estimated story points.
