Point of abstraction
A scrum point is an abstract unit of complexity of a user story. For developers, this concept usually takes a while to get accustomed to. Instead of estimating in development time, developers are asked to estimate a story’s complexity in terms of another reference story, which is commonly assigned 3 points.
This definition makes a point seem abstract since it does not have any unit of measure. For instance an estimate of 1 point does not mean the story will take 1 hour, 1 day or other conventional units of time.
