Abstract

Operational profiles are a quantification of usage patterns for a software application. These profiles are used to measure software reliability by testing the software in a manner that represents actual use. The current definition of an operational profile states that it is the set of operations available in the application, and the operations probabilities of occurrence in customer usage scenarios. This definition is too limited. In most industrial applications, focusing on operations alone does not offer adequate representation of the use of software. The limited definition of operational profiles can restrict their applicability and hence software reliability analysis for many software development organizations. This paper describes a formal and practical extension of the current definition of operational profiles to increase their applicability.
