Detailed
This requirement specifies that the system must do something with some information under certain circumstances. (Actor -Verb –Entity -Condition)
The difference between a mid level requirement statement and a detailed requirement statement lies in the visibility given to a screen display or a calculation/algorithm –what needs to be displayed and the actual calculation/algorithm are fully described in the detailed requirement.
Example: “The system must display the Products ordered, the quantity of each product, and any Options for each Product that was specified on the Customer’s last Order when the Customer is an existing Customer”
