Epics, Features and User Stories

The widely known definition of done is for user stories at the scrum team level. To evaluate the business value, consider the number of users that will use the functionality, how much will they use it, the urgency of releasing the feature, the ROI, the development effort, and the competition. Defining Features is a common practice in the Scaled Agile Framework, where they should fit in a Program.

Sometimes it is even substituted with another one if it is more functional and still meets the customer’s needs. In the agile environment, user stories are implemented to capture the functionalities and characteristics end-users need from the system under development. Every user story has three permanent elements that name the customer (who?), state the needed feature (what?) and express its intent (why?).

These are the attributes that the end-user finally likes to apply in the end product. These are known as ‘Specifications’ or ‘Requirements’ in the Agile development terminology. The success of a project relies on understanding the end-user requirements exactly and then applying accordingly in the end product. Therefore, the product features or requirements need to be completely known to the project development team.

Who Should Write User Stories?

That means the organization must also embrace agile principles from top to bottom to nurture momentum. A set of completed epics drives a specific initiative, which keeps the overall product definition of user story developing and evolving with market and customer demands on top of organizational themes. We focus on goals that “real” users will be able to work towards for a specific purpose.

But in the past few years, we never have found this type of document to be perfect. Back in 1999, Kent Beck coined a term called “User Stories” for the product attributes. He explained that the word User Story is best described from a customer’s point of view, what he or she wants to have instead of what system can do for him/her. Hence, the vision had a change from product to end-user finally and User Stories became the real standards for Requirements in all Agile processes.

Getting started with agile user stories

For example, the product owner has to know the cost of a user story to estimate the final priority in the backlog list. On the other hand, the Scrum team has to measure the size of the user story and determine if any more refinement is required. If they plan to work on a large user story, they need to split it into a number of smaller stories. The user stories are not written in the contract, but it is a call to the conversation. Instead, these stories hold the place for the conversations where the actual details will be transferable.

  • In some cases, however, they serve as a means to explain and develop system behavior later recorded in specifications supporting compliance, suppliers, traceability, or other needs.
  • At this state, the user stories have nothing more than a short description of user’s need.
  • In some cases, developers assign user stories a unique identifier and an effort/priority level.
  • Sadly, many of them are rants about how Agile is so unfriendly to UX and how the two cannot work together.
  • A set of completed epics drives a specific initiative, which keeps the overall product developing and evolving with market and customer demands on top of organizational themes.
  • Before that, the team should drill down to the specifics and solve usability problems at the outset.

User stories give us a firm grasp of the most important aspect in UX, the users and their wants. Examples of good outcomes are an X% increase in profile completion rates or an N% drop in payment flow errors. Outcomes that are tied to users or business goals free up the team to think about solutions to problems instead of churning out features for the sake of shipping something. We would also recommend you to provide information about what has to be done to perform the task described in the user story. Usually, this is done in the form of additional documents with assignments to the team members responsible for this kind of work. The development process becomes focused not only on the aims of a particular feature, but also on the reasons why the feature is implemented.

People using Agile and Scrum sometimes throw around terms and phrases and assume everyone listening understands what they mean. This is not only problematic – a kind of gatekeeping against people new to the field and/or not from a software background – but it does little to help people find new solutions for their challenges.

In reality, though, this is a shared responsibility among the entire cross-functional product team. Upon the development team has implemented a user story, the user story will be confirmed by the end user. He/she will be given access to the testing environment or a semi-complete software product (sometimes known as an alpha version) for confirming the feature. Confirmation will be performed based on the confirmation items written when detailing the user story. Until the confirmation is done, the user story is said to be in the Confirming state.

What are User Stories?

Therefore, they actively shifted the target from writing about features to explaining them. User stories need to place the user at the very core of the conversation. Product teams need to capture functionality from their perspective in order to identify ways to offer real value. To help you and your team fully understand what, who and why you’re building a product, user stories need to be short and to the point.

The illustration also shows a theme, which is depicted as a box grouping a set of stories together. A theme can be larger than an epic if, perhaps, you have a theme comprising eight medium-sized stories. But a theme can be smaller than an epic, as would be the case if you have a theme of a dozen simple spelling errors to correct. The team that invented user stories used the word theme to mean a collection of user stories. We could put a rubber band around that group of stories about monthly reporting and we’d call that a theme.

In software development and product management, a user story is an informal, natural language description of features of a software system. User stories are a way to describe the desired functionality of product backlog items. High-priority user stories tend to be more detailed; low-priority user stories tend to be less detailed.
