Story point Estimation guideline

A story point is a metric used in agile project management and development to estimate the difficulty of implementing a given user story, which is an abstract measure of effort required to implement it. In simple terms, a story point is a number that tells the team about the difficulty level of the story. Difficulty could be related to complexities, risks, and efforts involved.

Story point estimation, a kind of relative estimation, is typically performed at the Product Backlog Grooming Sessions and the Product Backlog is evaluated by the team who responsible for the actual development and testing work.

In most of the cases (and as defined by Scrum principles), the story pointing or estimation is done using some pre-decided base story. Every other story is pointed in respect to that story. However, if it is your first story or a new project, you can start with following simple chart.

Story points	Estimation effort
1	< 1 day
2	1
3	2-3 days
5	3-5 days
8	5+ days
8+	It is advised to break the story in simpler

Please note that this is what you do. Your style and the way your organization works might be slightly different. However, the basic idea remains the same. And the goal is also one - Success!
