An atomic requirement is one that is self-contained and can be understood independently of other requirements or designs. It encapsulates a single piece of functionality or a single need without reference to other requirements. This characteristic ensures that the requirement can be considered, implemented, and tested on its own merits. Atomic requirements are essential for clear communication, effective analysis, and traceability throughout the project lifecycle.
References: The concept of atomic requirements is discussed in various business analysis resources and is aligned with the guidelines provided by the International Institute of Business Analysis (IIBA). It is a fundamental aspect of creating clear and effective requirements documentation123.
