WHO estimate the effort of product backlog items?

Usually, estimation should be done in 2 levels at the start of each sprint: story level and task level. For best results, product owner and team should do both together, every time, although sometimes it is acceptable for the team estimate at task level without the product owner present.

How do you calculate product backlog and story points?

It is the estimated velocity. Since we know estimated team velocity and already have estimated product backlog, we can divide the total story point by velocity to get the number of iterations required to complete all PBIs.

Can the Product Owner estimate product backlog items?

The Product Owner brings Product Backlog Items to the Scrum Team to estimate their effort (cost). In order to create the right environment of safety and accountability, no Product Backlog Item is estimated by a single member of the Scrum Team, or even a subset of the team membership.

How does a scrum team arrive at an estimation for a product backlog item?

I advise teams to target three to four minutes on average per product backlog item. In this case, estimating 40 user stories would take no more than 160 minutes, or about 2-½ hours. The best way to do this is for a team to estimate its product backlog items in story points and its sprint backlog tasks in hours.

How many story points is a 2 week sprint?

You should be able to estimate about as many story points your team can manage during a two-week sprint, or whatever timeframe you’re working to. For example, if your team can usually get through 3 story points per day, this might add up to 30 story points across a two-week sprint.

Do you estimate user stories or tasks?

Usually, the estimation is done in two levels are for the PBI’s at the story level and the sprint backlog at the task level. You do the estimate of the user stories in the PBI’s when you have prioritized the items and are done with story point estimates as discussed above. 1.
