When assessing organizational structures, it is most helpful when subcriteria for each criterion are defined and linked to capability levels. Organizational structures are the arrangements of roles and responsibilities that enable the enterprise to achieve its objectives. Organizational structures can be assessed using six criteria:
clarity, comprehensiveness, integration, alignment, authority, and accountability. Each criterion can be further divided into subcriteria that describe the specific aspects or attributes of the criterion. Capability levels are the measures of how well a process or activity is performed in terms of effectiveness, efficiency, completeness, reliability, etc. Capability levels can range from 0 (incomplete) to 5 (optimizing). Defining and linking subcriteria to capability levels helps to evaluate the current and desired state of organizational structures, as well as to identify gaps and improvement opportunities.123 References: COBIT 2019 Framework:

Explanation
IT governance implementation risk is best managed throughout the life cycle of the implementation. IT governance implementation risk is the possibility of negative consequences or outcomes that may arise from the design, execution, evaluation, or improvement of the IT governance system. The life cycle of IT governance implementation is a continuous process that involves four phases: what are the drivers, where are we now, where do we want to be, and how do we get there. IT governance implementation risk should be managed throughout the life cycle by identifying, analyzing, evaluating, treating, monitoring, and communicating the risks that may affect the success of the implementation.12 References: COBIT 2019 Framework: Introduction and Methodology, COBIT 2019 Implementation Guide: Implementing an Information and Technology Governance Solution

According to the COBIT 2019 Design Guide, when designing an IT governance system, the next step after considering the enterprise's strategic business objectives is to assess the enterprise's risk profile. The enterprise's risk profile reflects the level of risk exposure and appetite that the organization is willing to accept in pursuit of its objectives. The risk profile also influences the selection of governance objectives, components and practices that are appropriate for managing IT-related risks.1, p. 18-19 References: 1: COBIT

Explanation
The transition from traditional waterfall to a more agile approach would impact the implementation method step in the design phase the most. The implementation method is the approach or strategy that is used to put the IT governance system into practice. The design phase is the stage in the IT governance life cycle that involves customizing and tailoring the IT governance system to the specific needs and context of the enterprise. The transition from traditional waterfall to a more agile approach would affect the implementation method step in the design phase because it would require a different way of planning, executing, monitoring, and controlling the IT governance system, as well as a different set of skills, tools, techniques, and practices.12 References: COBIT 2019 Framework: Introduction and Methodology, COBIT 2019 Design Guide: Designing an Information and Technology Governance Solution

Explanation
The primary objective of reviewing the effectiveness of a new IT governance system that has been operational for 6 months is to identify further governance requirements. An IT governance system is a set of components that provide direction, oversight, evaluation, monitoring, assurance, etc., for an enterprise's information and technology. The effectiveness of an IT governance system can be reviewed using different methods or tools, such as audits, assessments, surveys, feedbacks, etc. The primary objective of reviewing the effectiveness of a new IT governance system that has been operational for 6 months is to identify further governance requirements that may arise from changes in the internal or external environment, stakeholder needs, business objectives, etc.12 References: COBIT 2019 Framework: Introduction and Methodology, COBIT 2019 Implementation Guide: Implementing an Information and Technology Governance Solution
