A business analyst (BA) is verifying a set of requirements.

The requirement “After the customer has received an email confirmation, the customer is likely to access the order status in the order history which is available upon order submission” is not atomic because it includes multiple actions and outcomes within a single requirement. An atomic requirement should be independent, complete, and capable of being understood and implemented on its own without needing to refer to other requirements.

References: The concept of atomic requirements is discussed in the BABOK® Guide, which is a key resource for the CCBA® certification. It emphasizes that each requirement should address one single aspect to avoid confusion and ensure clarity and tractability12.
