1 1 1 1 2 CIO Examination of Strategic Decision Making for System Planning Phase Yukio Amagai 1 Masato Yokota 1 Masahiro Ide 1 Ryuichi Harada 1 Hironori Washizaki 2 Decision making in such as a systemization range and an information system investment during the system planning phase become harder because of the diversification of the realization methods and stakeholders, and the improper decision making may cause a delay or cancellation of the project. We propose the canvas model for the important decision making that solves the problems in the decision making and visualize the overall decision making elements to support the management layer including the CIO to carry out the investment on the suitable information system. We applied the proposed model to the actual system planning of the basic system and evaluated its usefulness. 1.
