It is approached through the Given/When/Then (GWT) sequence that looks like this: Scenario-oriented acceptance criteriaĪs the name suggests, the scenario-oriented format is the acceptance criteria type that comes in the scenario form and illustrates each criterion. However, you may find that other formats fit your product better so we’ll briefly touch on them as well. Most commonly used, the first and the second formats have very specific structures, so we’ll mainly focus on them. rule-oriented (the checklist template) and.scenario-oriented (the Given/When/Then template).Acceptance criteria types and structuresīased on the initial task and the complexity of requirements, acceptance criteria can be written in different formats, namely: That’s exactly what clearly written acceptance criteria do. Since different people can have different points of view and solution ideas regarding one problem, creating a unified vision of how the functionality should be implemented is necessary. Once the team has precise requirements, they can split user stories into tasks that can be correctly estimated. Acceptance criteria specify what exactly must be developed by the team. They can also be used to verify the story via automated tests.Ĭonducting feature evaluations. Each acceptance criterion must be independently testable and thus have clear pass or fail scenarios. AC are the basis of the user story acceptance testing. They ensure that everyone has a common understanding of the requirements: Developers know exactly what kind of behavior the feature must demonstrate, while stakeholders and the client understand what’s expected from the feature. Acceptance criteria synchronize the visions of the client and the development team. AC define these scenarios and explain how the system must react to them. Invalid password format is an example of a so-called negative scenario when a user does invalid inputs or behaves unexpectedly. Your AC may require the system to recognize unsafe password inputs and prevent a user from proceeding further. They provide precise details on functionality that help the team understand whether the story is completed and works as expected.ĭescribing negative scenarios. AC define the boundaries of user stories. To make the purposes of AC clearer, let’s break them down. Acceptance criteria main purposesĬlarifying the stakeholder’s requirements is a high-level goal. Otherwise, there’s a decent chance the deliverables won’t meet the needs and expectations of a client. Well-written acceptance criteria help avoid unexpected results in the end of a development stage and ensure that all stakeholders and users are satisfied with what they get.Īn important aspect in regard to acceptance criteria is that they have to be defined before the development team starts working on a particular user story. They are unique for each user story and define the feature behavior from the end-user’s perspective.Īcceptance criteria are the lowest-level functional requirements In this post, we’ll focus on acceptance criteria: We’ll clarify their purposes, types, and how they should be written (providing examples).Īcceptance criteria, explained What are the acceptance criteria and their role in projects?Īcceptance criteria (AC) are the conditions that a software product must meet to be accepted by a user, a customer, or other systems. While user stories aim at describing what exactly the user wants the system to do, the goal of acceptance criteria is to explain the conditions that a specific user story must satisfy. Here’s when user stories and acceptance criteria (AC) come into play as they are the main formats of documenting requirements. To prevent such issues from happening and provide a solution that meets the client’s needs and fits market requirements, there has to be high-quality software documentation. While this also works, your initial goal was to expose all available categories and let users explore further. fantasy, non-fiction, history, etc.) After two weeks of development, you receive a search bar feature where users must type in the category they are interested in, instead of browsing pre-listed categories. You expect to have a clear interface with category links to click on them (e.g. Imagine that you ask your development team to enable users to search for a product in an online bookstore by categories.
