1 Summary An in-depth and detailed review of the literature provides the basis and inspiration for research. As the basis of all excellent research, a good understanding of several key objectives of the literature review must be accomplished. For example, it defines the subject of the study, the context, the scope of the problem and, above all, the directions of the research. This is what we aim to achieve in this literature review on business process modeling notation (BPMN). Business process modeling notation is an important area for business process modeling. It allows business modelers to have a standard approach to model the business system with a high-level understanding of business processes. BPMN 1.0 was released to the public in 2004 and was developed by Business Process Management Initiative (BPMI) and was managed by Objective Management Group (OMG) [1]. The main goal of BPMN is to provide notation that is easily understandable by all business users. The widely acceptable point of this business process modeling approach is the success of industrial standardization. According to Alan Earls in his article "The Rise and Rise of BPMN for Process Modeling", BPMN was developed to version 2.0 in 2010, which is more stable and mature while offering XML to exchange executable or non-executable BPMN models. Certainly, the human mind prefers to understand graphics rather than paragraphs of text, and this becomes the motivation for the development of the graphics modeling language. Graphical process modeling has proven to be an effective approach to helping organizations document large businesses. By providing a Business Process Diagram (BPD), complex business models can be in the middle of paper applications. In the following sections of this literature review, we would like to present the following. Section 3 will be the context for the development of BPMN. Section 4 will introduce BPD in detail to provide a comprehensive understanding of how to use BPMN. Then, the section after section 4 describes how BPMN can improve processes, and some examples will be used. Section 5 presents our recommendations and comments on the current BPMN approach. Finally, the last section is the conclusion of this literature review.White, Stephen A. “Introduction to BPMN”. IBM Cooperation 2.0 (2004): 0.Thomas Davenport (1993).
