• Customer Representatives: In cases involving external clients, representatives from the client organization may perform UAT to verify that the software meets their specific requirements.

These participants test the software in real-world scenarios before it is fully deployed to ensure it functions correctly and meets their expectations.

Types of User Acceptance Testing

When preparing a new software solution for launch, User Acceptance Testing (UAT) can be of several types to ensure the product meets user expectations and business requirements:

• Alpha Testing: Alpha testing is conducted by the internal development team or QA professionals before the software is released to external testers. It focuses on finding bugs or major issues in the software’s functionality early in the development process.
• Beta Testing: After alpha testing, beta testing involves releasing the software to a selected group of external users. These testers interact with the software in real-world conditions, providing feedback on usability, performance, and any bugs encountered.
• Business Acceptance Testing (BAT): Once the software has been through alpha and beta testing phases, Business Acceptance Testing (BAT) validates that the software meets the business goals and solves the intended problems. This ensures the product is useful and relevant to the organization’s needs.
• Operational Acceptance Testing (OAT): Operational Acceptance Testing ensures that the software is ready for deployment and will perform reliably in a live environment. This phase covers system stability, performance, backup, and recovery processes.
• Contract Acceptance Testing: Contract Acceptance Testing checks if the software meets the terms and conditions outlined in the vendor-client contract. It ensures that agreed-upon specifications, features, and functionalities are fulfilled before final delivery.
• Regulation Acceptance Testing (Compliance Testing): Compliance testing verifies that the software adheres to relevant legal and regulatory standards for the market or industry in which it will be released. This ensures the software complies with necessary data protection laws, security standards, and industry-specific guidelines.
• Black Box Testing: Black Box Testing is an approach in which testers focus on the software’s functionality based on inputs and outputs, without any knowledge of the internal code or system structure. It evaluates whether the software performs as expected from the user’s perspective.

When should you conduct User Acceptance Testing?

User Acceptance Testing (UAT) should be conducted strategically in the software development to ensure the product meets user needs and business requirements. Here are some scenario-based points on when UAT should be performed:

• After Functional and System Testing is Completed: UAT should be conducted after the development team has completed functional and system testing. This ensures that the product functions correctly and meets real-world user expectations and business needs.
  For example, once a CRM system has passed all technical tests, UAT will confirm that it is ready for end users.
• Before Finalizing the Product Release: Perform UAT before the final release to ensure the product is user-friendly and aligns with business goals. This is crucial, for instance, before launching an updated e-commerce platform.
• When Introducing New Features or Updates: Conduct UAT when adding new features to verify they integrate smoothly with existing functionality and meet user needs, like a new time-tracking feature in a project management tool.
• Before Training End Users: UAT should occur before training staff on new software to ensure it functions correctly in real-world scenarios, such as a patient management system in a healthcare setting.
• When Adjusting to Changing Business Requirements: UAT is essential after implementing changes due to new business requirements, such as upgrading financial software to comply with new regulations, ensuring it meets user needs and compliance standards.

Conducting UAT at these key points helps ensure the software fully aligns with user needs, business requirements, and real-world scenarios before officially releasing it.

Steps to perform User Acceptance Testing

Performing User Acceptance Testing (UAT) involves several key steps to ensure the software meets user requirements and is ready for deployment. A structured approach can be:
