Why is Planning Poker considered effective ?
Planning Poker is considered effective in part because it’s collaborative. The whole team estimates effort for a User story or a backlog item and each member estimates the whole effort and not just his or her part of it. So this helps everyone on the team get a good understanding of the whole project.
Why is a Fibonacci sequence used for estimating User Stories ?
The reason for using the Fibonacci sequence instead of simply doubling each subsequent value is because estimating a task as exactly double the effort as another task is misleadingly precise. A task that is about twice as much effort as a 5, has to be evaluated as either a bit less than double (8) or a bit more than double (13).
What is a Burndown chart ?
A Burndown chart is a graphical representation of work left to do versus time. The outstanding work or the Sprint backlog is shown on the vertical axis and time along the horizontal axis. Burndown charts are useful for predicting when all of the work will be completed. The outstanding work is usually represented in terms of story points.
An example of Burndown chart is as follows –
