Description: Validation criteria are standards or references used to determine whether a product meets the required specifications. These criteria are fundamental in software development and project management, as they ensure that the results obtained are as expected and align with the established objectives. In the context of continuous integration and delivery tools, validation criteria are applied to verify that the source code compiles correctly and passes all automated tests before being integrated into the main branch of the project. In project management, these criteria help assess progress and the quality of deliverables. In behavior-driven development (BDD) and test-driven development (TDD), validation criteria are essential for defining the expected behavior of the software and ensuring that customer expectations are met. Finally, in the field of data collection and processing, validation criteria are used to ensure that the collected data is accurate and useful for subsequent analysis.
