Among the difficulties in developing software-intensive systems are the necessity of managing and controlling data that must be held for decades, as well as describing the needs and concerns of a variety of stakeholders. Therefore, one cannot neglect a good Software Engineering practice which is to develop software-intensive systems based on solid software architecture. However, the processes related to the software architecture of software-intensive systems are often considered only from a low level of abstraction. A recent architectural Standard, the ISO/IEC/IEEE 42020, defines 6 clauses for the architecture process, among them the Architecture Conceptual-ization process is the subject of this study. Considering that the ISO/IEC/IEEE 42020 has only recently been published, given the importance of establishing a well-defined software architecture, and considering the difficulties of understanding an architectural Standard, this work proposes a framework, and then the design and further evaluation of a web-based application to support soft-ware architects in using the activities and tasks of the Architecture Conceptualization clause based on the framework described. The ArchConcept was designed to address the high-level abstraction of the Standard ISO/IEC/IEEE 42020 and can be useful for software architects who want to follow ISO/IEC/IEEE 42020’s recommendation and achieve high-quality results in their work of software architecture conceptualization. A qualitative evaluation employing a questionnaire was carried out to obtain information about the perceptions of professionals regarding the ArchConcept, according to the Technology Acceptance Model (TAM). As ArchConcept is focused on activities of Archi-tecture Conceptualization, which is one of the early stages of a software project, the results found could be evidence of the short time dedicated to the initial phases of projects and their consequences.regarding the ArchConcept, according to the Technology Acceptance Model (TAM).
