Start with Acceptance Criteria: Laying the Foundation for Successful Software Development

Also Known As: Don’t Start Without Acceptance Criteria

Motivation: Establishing a Common Understanding

Before initiating any software development project, ensure that all stakeholders have a shared understanding of the goals and requirements. Acceptance criteria play a crucial role in this process, serving as a part of your Definition of Ready. It’s essential to note that simply documenting acceptance criteria is insufficient; automation of these criteria should be a priority as well.

Every piece of software developed should serve a specific purpose. Clearly capturing this purpose helps mitigate ambiguity often found in traditional documentation, such as Word files.

Applicability: Timing is Key

It’s best to define acceptance criteria for each feature or user story before implementation begins—preferably before the sprint starts. This approach equips the team with ample information about the feature, fostering more informed development practices.

Application: Defining Acceptance Criteria Effectively

1. Focus on the “What”: When establishing acceptance criteria, concentrate on the “What”—what the feature should accomplish in terms of business functionality—rather than the “How,” which pertains to the implementation details.
2. Clarify Expectations: Prior to beginning work on a feature or user story, ensure you understand the expectations of the business or product owner. This understanding should be as formal as possible, ideally structured in a way that facilitates easy automation.
3. Utilize Examples: Consider practical examples illustrating how the feature can be used. This not only helps clarify expectations but also prepares you for how to demonstrate the feature once it is built.
4. Collaborate with Stakeholders: Engage with business and development teams to refine acceptance criteria. This collaboration will enhance understanding and alignment on what the application will deliver.

Consequences: Improved Clarity and Collaboration

By starting with acceptance criteria, both business and development teams will have a clearer understanding of the software’s intended functionality. Developers will gain insight into the business objectives behind specific features, enabling them to suggest more effective solutions to achieve those goals.

Sample Approach: Specification by Example

One effective method for addressing acceptance criteria is through Specification by Example. This approach involves defining acceptance criteria in the form of practical usage examples, fostering a clearer understanding among all stakeholders.

Conclusion: The Importance of Acceptance Criteria

Integrating acceptance criteria into your software development process not only clarifies expectations but also promotes collaboration among stakeholders. By ensuring everyone is aligned on the desired outcomes, you can streamline development efforts and enhance the overall quality of your software products.
