What are story points and how do you estimate them?

Story points are a way to measure the relative size of user stories. The idea is that if you have two stories that both take 2 hours, they might be at different points on the scale. A story point is something you can use to estimate how much time it will take to complete a particular story.

To estimate story points, ask yourself: what's the smallest unit of work in this project? If I were to break up this project into smaller pieces, how many of those pieces would I need to do in order for it to be complete?

For example: if you're building an app that lets users order food online, and there are three main features—searching for restaurants, searching for items on their menu (like "cheese"), and placing an order—then your smallest unit of work might be "searching for restaurants." Once you've searched for five restaurants, then you've done enough work to get your feature complete!

Story points are a way of estimating the complexity of work. They are a unit that represents the amount of effort required to implement a feature.

The most common way to estimate story points is with use cases, user stories, or user scenarios. Each of these can be estimated in terms of story points so you can get an idea of how many stories are involved in each iteration.

For example, if we were going to estimate story points for the following use case: "As a user, I want to login so that I can see my profile." This could be estimated at 4–8 points depending on how complex it is and how much detail you put into it.

Story points are a way to estimate the complexity of a piece of work. The system involves assigning each piece of work a number based on how many people it would take to complete the task, as well as how long it would take them to do so.

For example, if you were working on a team that was creating a new app and one person had the job of creating all of the graphics for the app, they'd be given one point. If it took them five days to complete those graphics, then their point value would be five days multiplied by 24 hours per day (24 x 5), or 120 hours.

When estimating story points in this way, you should consider:

  • Who will do it?
  • How long will it take?

Story points are a unit of measure for the complexity of a task in Agile software development, and they're used to estimate work.

Story points are most commonly used in agile software development, but they can be applied to any kind of project. They're especially valuable because they help teams to communicate more clearly about the work that needs to be done.

There are three things that affect how many story points a task will have: difficulty, size, and risk. Difficulty is how difficult the task is for the person who's doing it; size is how much work there is; and risk is how likely it is that something will go wrong during development.
