A quantitative approach involves numeric mapping tables created for each of the design factors. According to the COBIT 2019 Design Guide, a quantitative approach is one of the four possible approaches for designing a governance system based on the design factors. A design factor is a characteristic of the enterprise that influences how the governance system should be designed. A quantitative approach uses numeric values to represent the impact of each design factor on the governance components, such as processes, organizational structures, roles, and practices. The numeric values are derived from mapping tables that show how each design factor affects each governance component. The mapping tables are based on empirical data, expert judgment, or best practices. The quantitative approach helps to provide a more objective and consistent way of designing a governance system that is tailored to the enterprise context and needs. References: : COBIT 2019 Design Guide: Designing an Information & Technology Governance Solution, page 54 : COBIT 2019 Design Guide: Designing an Information & Technology Governance Solution, page 56
