Can you please clarify this

Postby rajarshi_arjun Thu Jun 12, 2014 2:02 pm

The estimation unit of the Product backlog items is Story points or Ideal days and the estimation unit of the sprint back log items is ideal hours. But I am confused when do we use calendar days as an estimation unit. Can u please clarify.

In Agile estimation is done through expert opinion, analogy & disaggregation. Most appropriately combination if all these techniques which are not in terms of calendar days or the clock time but in terms of relative units which team defines how much will take.

Calender days are described in the framework of agile, e.g. In scrum, each iteration is 30 calendars days (fixed) how many ideal hours/story points work will be executed in this window is something team will define. Also the agile triangle emphasize on fixing schedule and making scope flexible in agile framework

Calendar days are not directly estimated but they gets calculated based on Size (can be in ideal days or story points) and velocity

Duration = Size /Velocity
