Many efforts have been made for modeling and standardizing software processes. ISO/IEC JTC1/SC7, the ISO sub-committee responsible for software and systems engineering, is one of the most important groups devoted to this task. However, standards developed by this committee are frequently inconsistent and even contradictory. This led to the need for an ISO Study Group to investigate the creation of an ontological infrastructure to establish a common conceptualization for underpinning all SC7 standards. This ISO initiative is a work in progress, which has focused on the software process domain and, in particular, considering the ISO/IEC 24744 standard. In this paper, we advocate in favor of using an Ontology Pattern Language (OPL) as the main component of this ontological infrastructure. We present ISP-OPL (ISO-based Software Process OPL), an OPL that can be applied as a basis for harmonizing software process-related standards, favoring reuse when building aligned specific software process ontologies for SE sub-domains. In order to illustrate its application, we also present an ontology about the Requirements Engineering process, developed by using ISP-OPL.

In order to evaluate its applicability, we conducted an experiment involving seven domain ontologies, developed using ISP-OPL.

Software organizations usually adopt quality standards for improving their testing processes. ISO provides different standards addressing the testing process, such as ISO/IEC 12207, ISO/IEC 29110 and ISO/IEC 29119. However, these standards are not properly aligned and, when used in combination, can give rise to conceptual inconsistencies and divergences. This paper presents an initiative harmonizing ISO testing processes extracted from these standards. Two ontologies were used in such initiative: a Software Process Ontology for harmonizing the standards’ structure, and a Reference Ontology on Software Testing (ROoST) for harmonizing standards’ content.
