Abstract
Conceptual modeling is supporting understanding and communication of the requirements in developing the information system (IS). The nature of requirements is usually divided into the functional (FRs) and non-functional requirements (NFRs). Thus, the scholars who are representing the conceptual modeling separate FRs and NFRs. Attempting to create an integrated framework for conceptual modeling of FRs and NFRs a new approach is being represented. In order to justify the approach, the research work and relevant literature in the field by using integrated perspective has been analyzed in this paper. As an outcome of this review, the need for an integrated approach to the requirement determination and proposed an integrated framework for conceptual modeling, which shall include the functional and non-functional requirements in one conceptual model has been identified. There is also identified that a small number of researchers have worked in this field, whilst the failure rate of the IS implementation which continues to be high has been the motivation, therefore the concept of proposing an integrated framework which will contribute to the increase of the efficacy of the requirements from the analysis phase in order to secure the sustainability of the IS has been approached.
Highlights
The information system (IS) is an integrated set of the Information and Communication Technology (ICT) components, human resources and processes which supports individuals, groups, organizations and society in achieving their business and societal goals
After proven that the success of conceptual model affects the success of the information system, is asked the research question, what is needed to improve the conceptual modeling? Based on this research questions, the focus turns to the nature of the functional and non-functional requirements and their integration in one conceptual model, source used for the conceptual modeling, quality applied in the conceptual modeling, instrument used to design the conceptual model and method which is used by the client for approval of the requirements and conceptual model
The objective in this paper is to present the rationale behind the proposal for integration of functional and non-functional requirements in one conceptual model, through a state of the art review for the identification of the research gap
Summary
The information system (IS) is an integrated set of the Information and Communication Technology (ICT) components, human resources and processes which supports individuals, groups, organizations and society in achieving their business and societal goals. System requirements importance in developing the successful information system is treated by scholars in 2016, who showed that participants involved in the project of the information system, start to clarify incompleteness and inconsistencies only during the phase of the system implementation but not at the phase of the system requirements, having an impact on the failure rate of the information system [5], [6]. Is needed to conduct research by identifying if the scholars have started to initiate the integration of the functional and non-functional requirements in one conceptual model. The objective in this paper is to present the rationale behind the proposal for integration of functional and non-functional requirements in one conceptual model, through a state of the art review for the identification of the research gap. This paper is organized as follows: in the section 2 is state of the art; in the section 3 are presented identified research gaps in the conceptual modeling; in the section 4 is presented the proposed integrated framework for conceptual modeling; in the section 5 is conclusion and future work; at the end, in the section 6 are presented the references used in this paper
