Explanation
The change enablement tasks are the tasks that involve preparing for managing and sustaining the changes that are required for implementing a governance system for an enterprise using COBIT 2019. The change enablement tasks help to ensure that the changes are aligned with the enterprise's strategy objectives needs expectations etc., that they deliver value and benefits to the enterprise and its stakeholders that they overcome resistance and barriers to change that they create a culture of continuous improvement etc. One of the key change enablement tasks that must be completed during the driver identification phase of an IT initiative is identify the business and governance drivers. The driver identification phase is the first phase of the governance implementation roadmap which involves identifying and analyzing the internal and external factors that trigger or influence the need for designing and implementing a governance system for an enterprise using COBIT 2019. The business drivers are the factors that relate to the enterprise's business strategy objectives performance risks issues opportunities etc., such as market conditions customer demands competitive pressures regulatory requirements etc. The governance drivers are the factors that relate to the enterprise's information and technology governance strategy objectives performance risks issues opportunities etc., such as IT alignment IT value delivery IT risk management IT resource management IT performance measurement etc. By identifying the business and governance drivers during the driver identification phase an enterprise can establish a clear understanding of why it needs to design and implement a governance system using COBIT 2019 what are the expected outcomes benefits value etc., from doing so who are the relevant stakeholders their roles responsibilities requirements expectations etc., how to communicate engage involve them in the change process etc.

Explanation
Business service continuity and availability is one of the 17 enterprise goals defined in COBIT 2019, which describe the outcomes that an enterprise wants to achieve from its use of information and technology. This goal relates to ensuring that critical business processes and information are available at a level acceptable to the enterprise in the event of a disruption or disaster, and that recovery plans are in place to restore normal operations as soon as possible. The goal is based on the COBIT 2019 Framework3, page 36. References: 3:

According to the COBIT 2019 Design Guide, a quantitative approach involves numeric mapping tables created for each of the design factors. This approach is used to assign numerical values to design factors and assess their relative importance in the governance system design. It provides a structured and systematic approach to decision-making and helps to ensure that the governance system design aligns with the enterprise's overall strategy and objectives.

The COBIT principle that addresses the need to consider how changes in technology or strategy impact the enterprise governance system as a whole is that a governance system should be dynamic. This principle states that "a governance system should be responsive to changing stakeholder needs, conditions and options; adaptable to changing circumstances; able to learn from experience; and innovative in supporting continual improvement" 4. A dynamic governance system can anticipate and respond to changes in the internal and external environment, such as new technologies, business models, risks, or opportunities5. References: 4:

Explanation
The alignment goal "Delivery of I&T services in line with business requirements" is organized into the customer dimension of the IT balanced scorecard (BSC). The IT BSC is a strategic performance management tool that helps enterprises to translate their IT vision and strategy into operational objectives and measures.
The IT BSC consists of four dimensions: customer, financial, internal, and learning and growth. The customer dimension focuses on how well IT meets the needs and expectations of its customers and stakeholders. Delivery of I&T services in line with business requirements is one of the 17 generic alignment goals defined by COBIT that supports the customer dimension.12 COBIT 2019 Framework:
