One form of implementing the information systems strategy is to invest in information technology (IT). One of the consideration that is often overlooked by top management in making decisions regarding IT investment is the aspect of organizational culture. This study aims to explore the characteristics and role of organizational culture in the perspective of each level of management on IT investment in the company. The initial data collection was carried out using the Organizational Culture Assessment Instrument (OCAI) framework given to 27 respondents to obtain an alternative organizational culture that was running, then a qualitative approach was carried out to determine organizational culture and its role in IT investment. The informants in this study were the General Manager, Procurement Manager, Network Operation Center (NOC) Manager, and Invoice Manager at PT Proxis Sahabat Indonesia. After analyzing using the Nvivo 12 application, it was found that the organizational culture perspective that emerged at each management level had a clan culture type. So that in making IT investments the decisions taken can accommodate every need from each level of management. Further research can use multinational companies to get more cultural diversity. Further research can also use a quantitative or mix-method approach to obtain a more diverse conceptual model.
