at the sprint task level at all, especially metrics that try to imply
whether the team is going to finish the sprint *for them*. This
should be a call the team makes considering the history of the sprint
to date (recorded as the burndown), what is left to do, and the
risk/uncertainty impacting the sprint currently.
If the ScrumMaster wants to draw a trendline then I would be
suspicious about the liberties they are taking in making assumptions
from that trendline. If the team wants a trendline then again I think
something is wrong because the team is asking for a crutch to tell
them how things will turn out in the sprint. In my experience, Scrum
teams know how they are doing each day if there are well-run daily
scrum meetings and generally good communication across the team.

Well, yes - just dumping it on the sprint burndown is probably not the most
effective way to use a trendline; it's certainly nothing I would suggest to
Take care, Ilja
