A Quantitative Evaluation Method for Evaluating the GSN Users’ Ability to Structuralize Systems with Multiple Viewpoints

Having multiple viewpoints is an indispensable capability for persons who lead the development and operation of large-scale, complex, technological and social systems. Previous studies state that structuralization with multiple viewpoints by using Goal Structuring Notation (GSN) refers to connecting multiple viewpoints in layers. If this study can quantitatively evaluate the ability to structuralize systems with multiple viewpoints of users describing GSN, it is likely to show that the evaluation is effective for human resource development. Previous studies have also shown that it is possible to increase the feasibility of accomplishing management vision and management strategy by describing management vision, management strategy, business process and IT system using GSN (D-Case). This study therefore proposes a quantitative evaluation method for evaluating the ability to structuralize systems with multiple viewpoints of users describing GSN. The verification method for the proposed quantitative evaluation method is also presented. The aim of verification in this study is to confirm that the proposed quantitative evaluation method can make a relative evaluation on the ability to structuralize systems with multiple viewpoints of users describing GSN. The subjects first described four themes using GSN. After that, we quantify the description results using the quantitative evaluation method. This study verifies that the proposed quantitative evaluation method is effective for evaluating the ability to structuralize systems with multiple viewpoints of users describing GSN by showing the quantitative evaluation results. Finally, this study concludes with future research topics.
