Explanation
The board of directors is the highest-level governance body in an enterprise that provides strategic direction, oversight, guidance, and approval for information and technology governance. The board of directors is accountable for monitoring the performance of the execution of an EGIT implementation program plan against success metrics and adjusting long-term targets when necessary. This means that the board of directors is responsible for ensuring that the EGIT implementation program plan is aligned with the enterprise's vision, mission, values, strategy, goals, and objectives, and that it delivers the expected value and benefits to the enterprise and its stakeholders. The board of directors is also responsible for reviewing the progress and outcomes of the EGIT implementation program plan on a regular basis, using predefined success metrics such as key performance indicators (KPIs), key goal indicators (KGIs), key risk indicators (KRIs), etc., to measure the achievement of the program objectives and goals. The board of directors is also responsible for adjusting the long-term targets of the EGIT implementation program plan when necessary, based on the changing business needs, environment, risks, opportunities, etc., and ensuring that the program remains relevant and effective.References: : COBIT 2019 Implementation Guide: page 37-38 : COBIT 2019 Framework:

According to the Official COBIT 2019 Study Manual from ISACA, Process Practices "are capability levels that can be used as benchmarks for the maturity of processes and for assessing process performance."

Explanation
A tailored enterprise governance system is a governance system that is customized to suit the specific needs and context of an enterprise. A sourcing model for information and technology is one of the design factors that influence the design and implementation of a tailored governance system. A sourcing model describes how the enterprise obtains and delivers I&T services, such as in-house, outsourced, cloud-based, etc. The sourcing model affects the governance objectives, components, and enablers that are relevant and applicable for the enterprise.12 References: COBIT 2019 Framework: Introduction and Methodology, COBIT 2019 Design Guide: Designing an Information and Technology Governance Solution
