Velocity v/s Burndown chart in scrum with simple example

In Scrum, both velocity and burndown charts are valuable tools used to track progress during a sprint.

Velocity:

Definition: Velocity refers to the amount of work a team can complete in a single sprint. It's typically measured in story points or tasks completed.

Usage: Velocity helps in forecasting how much work the team can accomplish in future sprints based on their historical performance. It's calculated by summing up the story points or tasks completed in the previous sprints and averaging them.

Example: Let's say in Sprint 1, the team completed 10 story points. In Sprint 2, they completed 12 story points. Therefore, the average velocity would be (10 + 12) / 2 = 11 story points per sprint.

Burndown Chart:

Definition: A burndown chart illustrates the amount of work remaining in a sprint over time. It tracks the completion of tasks or story points against the sprint timeline.

Usage: It helps the team visualize whether they are on track to complete all planned work by the end of the sprint. Ideally, the chart should show a downward trend as work gets completed.

Example: If a sprint has 50 story points planned and it lasts for two weeks, the burndown chart will display a line starting at 50 and gradually decreasing as the team completes tasks. Each day or iteration, the line should ideally move downward, reflecting completed work, aiming to reach zero by the end of the sprint.

Comparison:

Velocity measures the team's capacity and past performance, helping to forecast future sprints.

Burndown Chart visualizes the progress of the current sprint, showing whether the team is ahead, on, or behind schedule.

For instance, if a team has a velocity of 15 story points per sprint, they might plan work accordingly. Meanwhile, the burndown chart will track daily progress, showing if they're completing work at the expected rate.

These tools complement each other: velocity helps with sprint planning, while the burndown chart helps monitor and adjust the ongoing sprint progress.
