The COBIT 2019 publication that includes a workflow for planning a tailored governance system for the enterprise is COBIT 2019 Design Guide: Designing an Information and Technology Governance Solution.
This publication provides guidance on how to design a customized governance system for information and technology using COBIT as a reference framework. It includes a workflow for planning a tailored governance system for the enterprise that consists of seven steps: define design factors; define focus areas; define current state; define target state; identify gaps; define roadmap; select implementation method.14 References: COBIT

According to Capability Maturity Model Integration (CMMI), Level 2 within the five maturity levels for processes best describes the outcome of the process achieving its purpose through the application of a basic, yet complete, set of activities that can be characterized as performed. CMMI is a process improvement approach that provides organizations with the essential elements of effective processes. CMMI defines five maturity levels for processes, from 1 (initial) to 5 (optimizing). Level 2 (managed) means that the process is planned and executed in accordance with policy; employs skilled people who have adequate resources to produce controlled outputs; involves relevant stakeholders; is monitored, controlled, and reviewed; and is evaluated for adherence to its process description.12 References: CMMI for Development, Version

The function of a mapping table when determining the initial scope of a new governance system is to indicate the relevance of a governance or management objective with a particular design factor. A mapping table is a tool that helps to identify and prioritize the governance and management objectives that are most applicable and important for the enterprise, based on its specific characteristics and context. A design factor is one of the characteristics of the enterprise that influence the design and operation of a governance system, such as size, industry, culture, strategy, etc. A mapping table shows the degree of relevance of each governance and management objective with each design factor, using a scale from 0 (not relevant) to 5 (very relevant). The function is based on the COBIT 2019 Design Guide, page 23. References: : COBIT 2019 Design Guide | Digital | English

Stakeholder drivers and needs must be defined before determining alignment goals. Stakeholder drivers and needs are the requirements or expectations of the internal or external stakeholders of the enterprise, such as customers, employees, shareholders, regulators, etc. Alignment goals are the intermediate goals that link the enterprise goals with the governance and management objectives. Alignment goals are derived from the stakeholder drivers and needs, and they reflect how information and technology can support the enterprise strategy and objectives. Therefore, stakeholder drivers and needs must be defined before alignment goals can be determined.12 References: COBIT 2019 Framework: Introduction and Methodology, COBIT 2019 Framework: Governance System
