Almost every Scrum team uses them but they are not part of the official Scrum Guide. This article aims to remove some of the mystery surrounding Story Points.
I will also share the most common misconceptions I have encountered.
Each Story Point represents a normal distribution of time. For example: 1 Story Point could represent a range of 4—12 hours, 2 Story Points 10—20 hours and so on. This time distribution is unknown during estimation. You just want to have a rough indication of how planning time it will take to complete.
Story Points allow a team to:. A PBI requires implementation of a complex algorithm. The team has already done this before, so they will be able to do it quickly. The opposite can also be true, a simple PBI that takes a lot of time. The team needs to refactor a small piece of code affecting a lot of functionality. As a result a lot of functionality needs to regression tested and this will take a lot of time.Oct 22, · Watch the Video to understand what is Story Point, and Agile estimation.

Story Points provide a rough estimate. It could be that this item is extremely valuable or it does not add any value at all. You can take the effort into account to deliver that functionality together with the value. Story Points are about effort. Complexity, uncertainty and risk are factors that influence effort but each alone is not enough to determine effort.

Adjusting Story Point estimates of issues during sprint. When the story starts working on an issue, the team should not adjust points Story Point estimate. Even if it turns out that their estimate was inaccurate.

The bug represents work the team needs to complete. This does not apply if the team reserves a fixed percentage of time for working on bugs during the sprint.

We are in our sprint planning meeting. The Development Team DT are sat alongside the Product Owner PO who has bought along their prioritised product backlog, and the Scrum Master SM is about to kick the session off by defining the desired outcome of the meeting.
The desired outcome of the sprint planning meeting may be as follows:. As the session goes on, the product owner will talk through each story on the the product backlog.
The team will planning questions of the PO and of each other poker order to gain a shared understanding of the story. Once they think they have this, the SM will provide them with planning poker cards and the act of sizing will begin. The DT will be a group made story of people with different levels of experience, knowledge and skill. In this way it may be possible for anyone in the DT to pick up any story during the sprint.
To begin, the DT find a benchmark to relatively size each new story against. In sprint one, the SM may ask them to find an average size story on the product backlog. In later sprints, perhaps more appropriately, they may look back at stories already completed and find one with a size they now know to be accurate. The SM will ask the DT to decide individually the size of the story being discussed, and the DT will hold up the card representing that number points story points.
They will do so simultaneously so as not to be influenced by any other member of the team.

It may require another round or two of poker, but eventually consensus will be reached on size as members of planbing DT persuade each other with constructive reasoning. This process will be repeated with the next story on the product backlog, and then the next, and so on until the DT believe they have enough work to fill the sprint.
Pooints the SM will check to see how many story points have been planned. If this is the first sprint the DT have undertaken they will probably agree to start with what they have. If not, the SM will compare the number of points planned against team velocity.
