Alternate scrum burndown chart
|Reported by:||charris||Owned by:||Sam Bloomquist|
Check out the scrum burndown chart at http://www.mountaingoatsoftware.com/alt_releaseburndown. This is a great way to visualize the difference between work being added to a project and the work being completed. The most obvious benefit is that one can forecast the future project end-date more reliably.
Drwing bar charts above & below the x axis is easy enough - but how to do the two regressions isn't obvious to me. Because a project can have funny "bumps" in the burndown chart - it's not clear to me that you want to just do a blind regression trend line through the entire project.
Therefore, I would propose to add the two regression lines (one for tasks completed, the other for tasks added). The user then has 4 boxes (to enter the start & end dates for each trendline) which control the points over which the trendline happens.
