Which of the following involves numeric mapping tables created for each of the design factors?

The COBIT 2019 Design Guide introduces a methodology for designing a tailored governance system that relies on a series of design factors. To determine the relative importance of governance and management objectives, this methodology uses a quantitative approach. Specifically, it provides numeric mapping tables for each design factor. These tables assign a numerical value (e.g., on a scale of 1 to 5) to indicate the level of importance or relevance of each of the 40 core COBIT objectives based on the specific context of the enterprise's design factor (e.g., its chosen enterprise strategy or risk profile). This quantitative method allows for a calculated and repeatable process for prioritizing objectives.

A. An architecture design approach: This is too generic. While designing a governance system is a form of architecture, the specific method involving "numeric mapping tables" is best described as quantitative.
C. A qualitative approach: This is incorrect because the method explicitly uses numbers for mapping and calculation, which is the definition of a quantitative, not qualitative, approach.
D. A risk-based approach: This is too narrow. While the enterprise risk profile is a critical design factor, the use of numeric mapping tables applies to all design factors, not just risk.

1. ISACA, COBIT® 2019 Design Guide: Designing an Information and Technology Governance Solution, 2018, Section 3.2 "Design Factor Mapping Tables," p. 22. The text states, "For each design factor, a table has been created that maps the value/designation of the design factor to the importance of the 40 core COBIT governance and management objectives." The subsequent tables (e.g., Table 3.2, p. 23) clearly show numeric values for this mapping.

2. ISACA, COBIT® 2019 Design Guide: Designing an Information and Technology Governance Solution, 2018, Section 4.2 "Step 2. Initial scope of the governance system," p. 42. This section describes the process: "The initial scoping is based on the values for each of the design factors... The mapping tables in chapter 3 are used to derive an initial set of governance and management objectives..." This process relies on the quantitative values from the tables.
