agile story points definition
Because this unit is determined project by project, you can't compare story points from one project to another. Story points are used for iteration planning. In planning, teams make two simplifying assumptions. First, that a story point maps reasonably well to some amount of effort. Many agile tools (like JIRA Software) track story points, which makes reflecting on and re-calibrating estimates a lot easier. Try, for example, pulling up the last 5 user stories the team delivered with the story point value 8. Discuss whether each of those work items had a similar level of effort. A story point is an arbitrary, relative unit of story complexity. It's relative in that a two point story is twice as complex as a one point story. It's arbitrary in that there are no universal standards for how much complexity a story point represents. On each project, you pick a simple story and call that a 1. That is, that story has one story point. The best way I've found to do this is to bring a broad group of individuals representing various teams together and have them estimate a dozen or so product backlog items (ideally in the form of user stories in my opinion). No individual task should be more than 16 hours of work. (If you're using story points, you may decide that, say, 20 points is the upper limit.) It’s simply too hard to estimate individual work items larger than that with a high degree of confidence.

A user story is a very high-level definition of a requirement, containing just enough information so that the developers can produce a reasonable estimate of the effort to implement it. This article covers the following topics: Establishing a Common Baseline for Story Points. A common criticism of story points is that the meaning of a story point will differ among teams. In this post I want to describe how can we establish a common definition of a story point across multiple teams within an organization. Story points vs. hours. Traditional software teams give estimates in a time format: days, weeks, months. Many agile teams, however, have transitioned to story points. Story points rate the relative effort of work in a Fibonacci-like format: 0, 0.5, 1, 2, 3, 5, 8, 13, 20, 40, 100. Stakeholders write user stories. An important concept is that your project stakeholders write the user stories, not the developers. User stories are simple enough that people can learn to write them in a few minutes, so it makes sense that the domain experts (the stakeholders) write them. Use the simplest tool.
It rate the relative effort of work in a Fibonacci-like format: 0, 0.5, 1, 2, 3, 5, 8, 13, 20, 40, 100.
