Selecting Optimal Techniques for Crafting Acceptance Criteria in Agile Projects: A Business Analyst's Perspective
In the Agile development landscape, the role of a Business Analyst (BA) is both dynamic and critical, especially when it comes to building robust acceptance criteria for user stories. Acceptance criteria are the benchmarks that determine whether a user story has been completed successfully, playing a pivotal role in guiding development and ensuring that deliverables meet user needs and business objectives. Given the plethora of business analysis techniques available, choosing the most effective ones for crafting acceptance criteria can significantly influence the success of Agile projects. This article explores how BAs can pick the best techniques for this purpose and how to enhance their Agile business analysis for better project outcomes, whether in Agile or Waterfall environments.
Understanding the Agile Context
In Agile projects, user stories describe features from the perspective of the end-user, emphasizing value delivery over technical specifications. The acceptance criteria attached to these stories serve as the definition of "done," providing clear and testable conditions that must be met for the story to be considered complete. The choice of business analysis techniques for developing these criteria is crucial, as it directly impacts the clarity, testability, and achievability of project goals.
Powerful Techniques for Building Acceptance Criteria
1. Behavior-Driven Development (BDD): BDD focuses on the expected behavior of a system from the user's standpoint, making it an excellent technique for defining acceptance criteria. BAs can use BDD to frame acceptance criteria in a given-when-then format, which is straightforward and testable.
2. Specification by Example: This technique involves using real-world examples to specify what is expected of a feature, providing a clear guide for development. By working with stakeholders to generate examples, BAs can develop precise and relevant acceptance criteria.
3. User Story Mapping: Although primarily a planning tool, user story mapping can help BAs understand the broader context of a user story, ensuring that acceptance criteria are comprehensive and aligned with the user journey.
4. Impact Mapping: Impact mapping is a strategic planning technique that helps teams stay focused on delivering the most valuable features first. By understanding the desired impact, BAs can formulate acceptance criteria that ensure each user story contributes effectively to project goals.
Choosing the Right Business Analysis Technique
The selection of the most appropriate technique for building acceptance criteria depends on several factors:
- Project Complexity: More complex projects might benefit from techniques like Impact Mapping to ensure that acceptance criteria align with strategic objectives.
- Team Dynamics: The experience and preferences of the development team can influence the choice of technique. Teams familiar with BDD, for example, might find it more natural to use this approach for defining acceptance criteria.
- Stakeholder Engagement: Techniques that facilitate stakeholder involvement, such as Specification by Example, can be particularly effective in projects where stakeholder input is crucial for defining success.
Elevating Agile Business Analysis
To enhance their practice and contribute more effectively to both Agile and Waterfall projects, BAs can adopt the following strategies:
1. Continuous Skill Development: Staying updated with the latest business analysis techniques and Agile methodologies ensures that BAs can apply the most effective strategies for the task at hand.
2. Cross-Methodology Proficiency: Understanding the nuances of both Agile and Waterfall methodologies allows BAs to adapt their approach according to the project's needs, applying Agile techniques like BDD even in more structured Waterfall environments when appropriate.
3. Systems Thinking: Employing systems thinking enables BAs to see the bigger picture, ensuring that acceptance criteria for individual user stories align with broader system requirements and business objectives.
4. Collaborative Workshops: Facilitating workshops with stakeholders and development teams can help in co-creating acceptance criteria, ensuring they are both achievable and aligned with user needs.
5. Feedback Loops: Establishing regular feedback loops with the development team and stakeholders helps in refining the acceptance criteria over time, ensuring they remain relevant and effective throughout the project lifecycle.
Tips for Writing Acceptance Criteria
Each PBI must have acceptance criteria. The acceptance criteria should be to a level of detail that ensures the card is testable and clearly communicates expectations of the cards outcome to the team.
Acceptance criteria is completed before sprint planning as it assist in planning more effectively by helping the team understand the card more meaningfully for estimation and selection of the card for the sprint. Although acceptance criteria may need to be adjusted during development, having acceptance criteria prior to development is more meaningful.
The team can reject a card for sprint planning because the acceptance criteria is either no understandable or not in enough detail. The team should set its expectations for the acceptance criteria’s level of detail in the team working agreement. The objective is for the team to move quickly in development and not to stop and wait for clarification of acceptance criteria as much as possible.
Each acceptance criteria statement must be able to be tested with a clear pass / fail result. If it can’t be tested, it’s even harder to develop. Set clear expectations in the acceptance criteria.
Acceptance criteria focuses on the “What” or end result not the “How” or solution.
Acceptance criteria can contain both functional (visible by the role) or non-functional (behind the scenes activities) as needed.
Acceptance criteria should be focused on providing capabilities that are delighting the customer and improving the customer’s relationship with the overall product.
Describe the negative scenarios - and a recovery path. Acceptance criteria doesn’t need to be kept positive. If there are pitfalls or potential errors for a customer, consider elaborating. Password entered is not correct? What is the end result? What is the error message?
Techniques for Creating Acceptance Criteria
1. User Story Breakdown
Understand the User Story: Ensure a clear and thorough understanding of the user story, focusing on the user's needs and the value the story provides. How does this card fit into the customer journey? What process is associated with this card?
Break Down Complex Stories: For large or complex user stories, break them down into smaller, manageable pieces to simplify the creation of acceptance criteria. Large complex cards require even larger amounts of acceptance criteria which can make them harder to develop and test. Cards with 7 - 13 acceptance criteria statements are easier to develop. Why? Most developers can remember 7 - 13 statements in their minds when developing without having to look back at the card.
2. Collaboration and Communication
Involve Relevant Stakeholders: Engage product owners, developers, testers, and designers in the process to gather diverse perspectives.
Use Three Amigos Meetings: This is a meeting that involves a business analyst (or product owner), a developer, and a tester to discuss the user story and its acceptance criteria to ensure a shared understanding. It’s a collaborative session to explain the card to the 3 Amigos and to brainstorm on potentially spitting the story, combing it with other stories, or seeking additional information. The meeting also is reviewing and brainstorming acceptance criteria.
3. Specification by Example
Provide Clear Examples: Use specific examples to clarify requirements, which can serve as a basis for tests. Clear examples assist in creating automated test cases more effectively.
Use Behavior-Driven Development (BDD) Syntax: Adopt a Given-When-Then format to structure acceptance criteria as scenarios, which can be directly converted into automated tests.
4. INVEST Principle
Ensure that the user stories and their acceptance criteria are:
Independent: Can be developed and delivered independently.
Negotiable: Open to discussion and refinement.
Valuable: Provide value to the end user.
Estimable: Clear enough to estimate development effort.
Small: Small enough to be developed within an iteration.
Testable: Can be verified through tests.
5. Definition of Done (DoD)
Align with DoD: Ensure that acceptance criteria align with the team's Definition of Done, encapsulating all conditions that must be met for the user story to be considered complete. DoD is typically outlines int eh team’s working agreement.
Don’t Forget DoR: The definition of ready outlines what the team expects to be completed and the level of detail they require in order to start considering it as part of sprint planning. The level of detail in acceptance criteria is outlined the team’s working agreement.
6. Prioritization
Must Have vs. Nice to Have: Distinguish between essential criteria and those that are desirable but not critical, which can aid in prioritization during development.
Utilize the nuisance scale or some other technique for prioritization of the user story. High priority user stories are stories that resolve significant customer nuisance points or paint points and deliver the most business value.
Product roadmaps are useful in the prioritization process. The roadmap indicates which capabilities and features the Product Manager, stakeholders, and customer are expecting. You will still need to further refine the prioritization using other methods such as Kano, MoSCoW, 20/20, or Walking Skeleton.
7. Clarity and Simplicity
Use Clear, Concise Language: Write acceptance criteria in simple language, avoiding technical jargon to make it accessible to all stakeholders.
Be Specific and Measurable: Criteria should be specific and quantifiable to remove ambiguity and facilitate testing.
8. Feedback and Refinement
Iterative Refinement: Acceptance criteria can evolve and be refined as more is learned about the user story or feature.
Incorporate Feedback: Use feedback from stakeholders, especially after sprint reviews, to refine and update acceptance criteria.
9. Testing and Validation
Automatable: Where possible, write acceptance criteria in a way that can be automated for testing.
Manual Testing: For aspects that can't be automated, ensure that criteria are clear enough for manual testing.
Work with a Quality Control or Quality Assurance professional that understands how to test for defects to craft acceptance criteria that is useful for both development and testing.
10. Documentation and Accessibility
Accessible Documentation: Ensure that acceptance criteria are documented and accessible to all team members and stakeholders.
Regular Review: Regularly review acceptance criteria with the team and stakeholders to ensure they remain relevant and accurate.
