A study on the priority decision making of IT goals in COBIT 5 goals cascade

Nowadays, as IT becomes a key element in most business models, it is very important for countries and corporations to create effective business / IT value from IT-related investments. To do so, the process and structure for business / IT value creation must be designed appropriately for the organization's goals and context. For this, the IT governance models that organizations can use typically include COBIT(Control Objectives for Information and Related Technologies) 5, ITIL (IT Infrastructure Library), and TOGAF (The Open Group Architecture Framework). This research helps to use the COBIT 5 Goals Cascade when companies use COBIT 5 to design processes for business / IT value creation. The COBIT 5 Goals Cascade is a mechanism that translates the needs of stakeholders into actionable and customized enterprise goals, IT-related goals and enabler goals. However, this mechanism does not give priority to what goals should be prioritized. According to the COBIT 5 Enterprise Goals to IT-related Goals Mapping table, multiple IT-related goals must be fulfilled to achieve a single enterprise goal. As a result, the IT-related goals for some enterprise goals will be much larger, confusing which goals should be undertaken. To contribute to this problem, this research presents a prioritized methodology that determines the IT-related goals that are more relevant to the organization's goals in realizing IT-related goals. This prioritization methodology is based on the AHP(Analytic Hierarchy Process) using the 'Balanced Scorecard' and 'Governance Objectives' as indicators.
