Acceptance criteria

Acceptance criteria are predefined standards or requirements a product or project must meet in order to be accepted by the stakeholders, end users, or customers. They are used in many fields, including software development, project management, and product design.

Definition

Acceptance criteria are a set of conditions that are used to confirm when a specific task is completed and meets the required standards. They are typically defined by the product owner or stakeholders and are used to ensure that all requirements of a task are met.

Purpose

The purpose of acceptance criteria is to clearly define the boundaries of a user story or task, and to ensure that the requirements are clearly understood by all parties involved. They provide a clear understanding of what is expected and help to avoid any misunderstandings or misinterpretations.

Types of Acceptance Criteria

There are two main types of acceptance criteria: functional and non-functional.

Functional Acceptance Criteria

Functional acceptance criteria are related to the functionality of a product or system. They define what a system is supposed to do and include specific behaviors or functions. For example, in a software application, a functional acceptance criterion might be that the application must allow users to create a new account.

Non-Functional Acceptance Criteria

Non-functional acceptance criteria are related to the performance, reliability, and usability of a product or system. They define how a system is supposed to be, rather than what it is supposed to do. For example, a non-functional acceptance criterion might be that the system must be able to handle a certain number of users at the same time.

Writing Acceptance Criteria

When writing acceptance criteria, it is important to be specific, clear, and concise. They should be written in a way that is easy to understand and testable. They should also be realistic and achievable, and they should not be too broad or too narrow.

Testing and Acceptance Criteria

Acceptance criteria play a crucial role in software testing. They provide a basis for the test cases that will be used to verify that a system or product meets the required standards. They also provide a clear definition of done, which helps to ensure that all tasks are completed to the required standard.
