What problem do you see if the scope increases or decreases considering sprint goal is met? Isn't it focused to increase transparency in team rather judging the trend line variations? X Login.

Hi, I am working as a Product Owner and I would like to introduce Release burndown chart to my product. Joerg Keller.
Ian Mitchell. Above shows that the work has been overestimated. Actually it has been completed faster than estimated. The team can add more work, and there is a need to re-estimate.
Generally, anyone can use burndown charts, even construction contractors, editors, movie makers, basically the people who want to manage an estimated amount of work over a period of time. I have made a simple template in MS Excel which will help chart the burndown of any work.
There are several burndown charts that we will see in this article such as the sprint burndown chart and product burndown chart along with the release burndown chart.
In this chart, the sprints are plotted in the x-axis and remaining efforts or the release efforts on the y-axis. The efforts are measured in hours or days or story points. The scrum master updates the release burndown chart with actual progress made at the end of each sprint before the next sprint starts. Example: A website development for a customer has to be made ready. The effort is sprint into a 2-week long sprint. There ideally 3 sprints are required or 6 weeks of efforts for the first version of the website to be ready.
There are 2 people on the team. Having the 6 hours daily gives the development team to relax and spend time on their organizational commitments without affecting the progress of the development.
The release burndown chart can be plotted as a line chart. The y-axis consists of hours and sprints on the x-axis. There are two lines one green and another red.
The red line is the ideal time, and the green line is the effort remaining. If the green line is plotted is below the red line then the team is accomplishing tasks as planned in the sprints. For Date-Based Release Plans, we multiply the team velocity by the number of Sprints we have until the release date. That is going to reveal the estimated total number of user story points the Scrum Team can deliver until the release date.
What we don't know: Can the Scrum Team deliver the requested features until the given deadline? We multiply the team velocity by the number of Sprints we have until the release date.
If this number is larger than the sum of user story points of features within a release, then we're safe. Otherwise, the velocity of the Scrum Team needs to be extended by adding extra human resources to the team.
That may not be a viable option as the Scrum team could already possess 9 people, which is the upper limit of an ideal size of a Scrum Team. Then some user stories of the project need to be delivered by another Scrum Team, which is going to work with the original Scrum Team in parallel. It will change during the whole project while we know more about the project. Therefore, the release plan should be revisited and refreshed at regular intervals.
