To determine how many sprints for a User Stories

 To determine how many sprints it will take to complete 59 user stories and how many story points to assign to each user story, we need to break this down step-by-step:

Step 1: Estimate the Story Points

• Assess the Complexity: First, you need to estimate the complexity of each user story. Story points are often assigned based on factors like effort, risk, and complexity. Use techniques like planning poker or t-shirt sizing to estimate.
• Typical Scale: Story points are often estimated using Fibonacci-like sequences (e.g., 1, 2, 3, 5, 8, 13, 21) or other scales that represent effort.

Step 2: Determine Team Velocity

• Velocity: Velocity is the number of story points a team can complete in one sprint. For example, if the team completes 30 story points in a 2-week sprint, their velocity is 30.
• Historical Data: If the team has historical data, use that to determine their average velocity. If not, start with a rough estimate based on team capacity.

Step 3: Calculate Number of Sprints

Once you know the total number of story points for all 59 user stories and the team’s velocity, you can calculate the number of sprints required.

Formula: $\text{Number of Sprints} = \frac{\text{Total Story Points}}{\text{Velocity per Sprint}}$

Example Scenario

Let’s assume:

• Average story points per user story: 5
• Velocity: 30 story points per sprint

1. Total Story Points:
   $59 \, \text{user stories} \times 5 \, \text{story points per user story} = 295 \, \text{total story points}$

2. Number of Sprints:
   $\frac{295 \, \text{total story points}}{30 \, \text{velocity per sprint}} = 9.83 \approx 10 \, \text{sprints}$
   

Conclusion

• It would take approximately 10 sprints to complete all 59 user stories, given the assumptions in the example.
• The story points per user story can vary, but the overall estimate will guide you on how many sprints are needed. Adjust the story points per story based on detailed estimations.
