Observability in the context of a System Under Test (SUT) refers to the degree to which the system provides insights into its behavior, allowing users to understand the status of various actions performed. This enables users to verify that the system’s actual behavior matches the expected behavior. Observability is crucial for diagnosing issues, understanding system performance, and ensuring that the system functions correctly.

References = The concept of observability is covered in the ISTQB Test Automation Engineer syllabus, which discusses the importance of designing a system that provides clear and understandable interfaces giving control and visibility on all test levels. This includes the ability of the SUT to provide interfaces that give insight into the system, which is essential for creating effective and maintainable automated tests1.
