The module is fantastic! Our core user teams are working Scrum, so it was exactly what we needed to evaluate our progress.
Now that we can clearly map our burn down rate, we can finally see easily if we will meet our targets.
I suspect that many users may not be aware of how significant this type of reporting is to effectively manage projects. Once I get a chance to sit down and explain users within our organization how it works, they immediately get it and realize that traditional charting is not half as effective or useful.
