Guide to Know Everything about the Story Points and Agile Estimation
Are you someone how don't know what a Story Point is OR someone who wants to eliminate common mistakes when it comes to Story Point Estimation OR someone who is not able to make a successful Story Point Estimation...
Then this guide on Story Points and Agile Estimation is all you need to know everything regarding the Agile Estimation and Story Points.
First, we will start by knowing what exactly are Story Points and what is their function.
The term Story Point can be defined as a metric that is used in the Agile Development and Management field for the purpose of determining the difficulty level of implementing a particular story.
So, for a given business the story needs to be initially assigned to the team of software development. With the estimations of story points, the development team doesn't have to be too precise with their schedule.
Sometimes it may be a little complex, let's say, in case of how long a particular feature will take to be completed developed, the development team will be assigning more story points to it. These extra story points will help in making the situation easy to understand.
The story points can be expressed in two different ways like:
Now, we know that a story point is a summarized symbolic measure that is required to estimate the time required to implement a user story. In other words, it is a number that briefly informs the development team about the difficulty level of a particular story.
This level of difficulty is in regards to the complexities as well as the risks and efforts involved in the user story. The scaling or process to estimate story point can be described as - 1,2,3,5,8,13 [Fibonacci Series] and Extra Small, Small, Medium, Large [ T-Shirt Size Chart].
Sometimes it can be hard to estimate especially for the team of developers. For software developers, Agile Estimation can be a difficult task to project accurately. Let's take a look at some of the ways that can help in making this agile estimation as accurate as possible:
Team involvement in Agile Estimation - Every single one of the team member should be involved when it comes to agile estimation. This is because each team member like the designer, tester, developer etc. has a different perspective of the product and require a different amount of duration to deliver his/her part of a user story.
Coordinating with Product Manager - In the process of Agile Development, the product manager is the one with the completed list of the user story and its feature requirement with short descriptions attached to it. Whenever an agile development process is started, the issues that the development team usually face are related to the requirements of the user stories. Here, the product manager can guide them through each requirement of a user story.
Earlier the project development teams would opt for the traditional method of providing their project estimation in the format of Hours, Days, Weeks, and even months. But now, the team of developers uses the Fibonacci sequence like 1,2,3,5,13 and so on for representing their agile estimation of the project.
Although, it may look complex but using these story points can come very handy in difficult stages during the process of software development.
When dealing with Story Points there are a number of things that you should know. These are some of the most common mistakes that are made when using these story points:
To translate the story points into the hours - If you are someone who translates the story points into hours, you just spoiled the whole point behind the speed of relative estimation. This is because it further provides you a false sense of accuracy and then it becomes more and more difficult to reach the previously calculated agreement.
To average out the story points - For example, if the development team is divided into two parts and one half of the team wants to set the PBI at 3 points whereas the other half of the team wants 5 points to be set. This can be easily resolved by setting the PBI at 4 points. But then the team should not again attempt to provide a false sense of accuracy with the difference between points.
The concept of Story Points in Agile Estimation is simple to apply but it requires appropriate amount of practice to master this technique. Our team of experts recommends implementing this method to the development teams to help them speed up their relative estimation.
