Abstract
Business requirement definitions are often necessary in developing information systems and the first activity is stakeholder requirement elicitation. Therefore, the primary stakeholder in information systems is considered the baseline stakeholder and the related stakeholders are distinguished through information with this baseline stakeholder. There are three problems with the conventional stakeholder distinction methods. (1) The information between stakeholders is incomprehensible. (2) Demarcating the roles and responsibility of stakeholders is impossible. (3) It is impossible to transfer the information between stakeholders to downstream processes. The G-RD (Global Relations Diagram of Function and Demarcation) is a relation diagram focusing on information between businesses. The G-RD defines an element as an entity that sends or receives information and this information between elements is defined as a relation. If a stakeholder is defined as an element utilizing G-RD, information between stakeholders becomes clear and the three problems of conventional stakeholder distinction methods can be solved. This paper examines a case study, which applies the G-RD to business requirements definitions and information systems requirements definitions, and confirms the effectiveness of the G-RD.
