Question

Hello ,

I need to understand in simple words the below Burndown chart. What is the guideline and the straight red line?

Also the velocity chart down here-

Jack Brickey · Answer

burndown - a graphical view of actual logged work vs. the plan. The chart illustrates a downward trend from "full" to "empty" where "full" equates to the total number of story points for a sprint and "empty" equates to completing all work.

velocity - provides an average amount of work a team has demonstrated they can achieve over a period of time. This is generally illustrated in story points, e.g. my team of 5 engineers has shown they can achieve 60-70 SP over a two week sprint. Things that greatly influence accuracy/reliability:

* consistent team members and availability
* many historic sprints to base the average on
* consistent estimation process
* all things being equal... the more sprints a team goes thru the more reliable the velocity is
