Abstract: “Business Process Reengineering provides an efficient and effective change in the way in which work is performed. During the traditional system development life cycle,there are some limitations within the system analysis stage such as poor communication and lack of a common language between the user and the analyst and between the analyst and the designer. To tackle this challenge, this paper presents an integrated methodology of Structural System Analysis and Information Technology.. The real data based on a case study at mix Grill restaurant in Irbid Jordan is collected then analyzed using the proposed technique to build data and process model. All results demonstrate that the proposed method is both effective and efficient for Business Process Re-Engineering.In fact, it can significantly enhance the business process and thus, gain and sustain the competitive advantage.”
