Explanation: The high-level program plan is a document that describes the rationale, objectives, scope, approach, benefits, costs, risks, and timeline of the EGIT implementation program. The EGIT implementation program is a program that involves designing and implementing a governance system for an enterprise using COBIT 2019. The high-level program plan provides the basis for obtaining approval, funding, resources, and support for the program from the stakeholders. The high-level program plan is an output of the “what needs to be done” phase. The “what needs to be done” phase is the fourth phase of the governance implementation roadmap, which involves defining the target state of information and technology governance in an enterprise that is aligned with its strategy, objectives, and stakeholder needs. This phase also involves identifying the gaps and issues that need to be addressed to achieve the target state, setting the improvement targets and priorities, developing a detailed business case and a high-level program plan for implementing a governance system using COBIT 2019. By developing a high-level program plan as an output of the “what needs to be done” phase, an enterprise can ensure that it has a clear and realistic roadmap for designing and implementing a governance system using COBIT 2019, that it has defined the expected outcomes, benefits, value, etc., from doing so, that it has considered the relevant risks, costs, resources, etc., involved in doing so, that it has obtained stakeholder buy-in and commitment for doing so, etc.References: : COBIT 2019 Implementation Guide: page 39-40 : COBIT 2019 Implementation Guide: page 41-42
