Abstract
This paper presents a controlled experiment in which two different requirements specification styles (white-box and black-box) were compared concerning the understandability of two requirements specifications from the viewpoint of a customer. The results of the experiment confirm the common belief that black-box requirements specifications (e.g., documented with SCR) are easier to understand from a customer point of view than white-box specifications (e.g., documented with UML). Questions about particular functions and behavior of the specified system were answered faster and more correctly by the participants. This result suggests that using a black-box specification style when communicating with customers is beneficial.
