The PRIMARY purpose of information governance is to set direction for information management capabilities through prioritization and decision making. Information governance is the overall strategy for information at an organization. It balances the risk that information presents with the value that information provides1. Information governance helps with legal compliance, operational transparency, and reducing expenditures associated with legal discovery1. To achieve this, information governance requires setting direction for information management capabilities through prioritization and decision making. This involves defining and implementing policies and processes for the effective and efficient acquisition, storage, distribution, usage, and disposal of information in alignment with business objectives and regulatory requirements2. It also involves ensuring the protection of information quality, integrity, availability, confidentiality, and ownership2. By setting direction for information management capabilities through prioritization and decision making, information governance can help to optimize the value and minimize the risk of information assets.

Enterprise architecture (EA) is the most useful in developing IT strategic plans aligned with technological needs because it provides a holistic view of the current and desired state of the organization, including its business processes, information systems, data, applications, infrastructure, and security. EA helps to align the organization's vision, strategy, and goals with its IT capabilities and resources. EA also helps to identify the gaps, risks, and opportunities for improvement in the existing IT environment and to design and implement the optimal IT solutions that can support the business needs and objectives. EA can help to ensure that the IT strategic plans are consistent, coherent, and feasible12.
A business impact analysis (BIA) is a tool that helps to assess the potential impact of a disruption or change on the business objectives, processes, and functions. A BIA can help to prioritize the criticality of the IT resources and determine the acceptable level of risk and recovery time. A BIA can provide a basis for deciding how to allocate the budget, reduce the requirements, or contract external resources3. However, a BIA is not sufficient for developing IT strategic plans aligned with technological needs because it does not provide a comprehensive view of the current and future IT architecture and its alignment with the business strategy.
A business case is a document that describes the rationale and justification for initiating a project or investment. A business case can help to evaluate the costs, benefits, risks, and alternatives of different IT options and to communicate the value proposition to the stakeholders4. However, a business case is not enough for developing IT strategic plans aligned with technological needs because it does not provide a holistic view of the current and future IT architecture and its alignment with the business strategy.
A benchmark analysis is a process of comparing the performance, quality, or practices of an organization with those of its peers or competitors. A benchmark analysis can help to identify the best practices, standards, or trends in the industry and to measure the gap between the current and desired state of an organization.
However, a benchmark analysis is not adequate for developing IT strategic plans aligned with technological needs because it does not provide a holistic view of the current and future IT architecture and its alignment with the business strategy.

To enable the development of required IT skill sets for the enterprise, it is most important to define skill requirements based on each role within the IT department, because different roles may have different responsibilities, tasks, and expectations that require specific skills and competencies. By defining skill requirements based on each role, the enterprise can ensure that the IT staff have the appropriate knowledge, abilities, and experience to perform their roles effectively and efficiently, and to support the enterprise's goals and objectives. According to ISACA's CGEIT Domain 2: IT Resources1, "the enterprise should identify the skills required for each IT role and assess the current and future skill gaps." Furthermore, according to ISACA's article on IT Skills Gap2, "the skills gap is not a one-size-fits-all problem. It varies by industry, organization and department/role." Therefore, defining skill requirements based on each role within the IT department is the best way to enable the development of required IT skill sets for the enterprise. References:

One of the primary responsibilities of a data steward is to classify and label organizational data assets, which means to assign categories and tags to the data based on its characteristics, such as type, source, sensitivity, quality, or purpose. Classifying and labeling data helps to organize, manage, and protect the data assets, as well as to facilitate their discovery, access, and usage. Data stewards are also responsible for defining and maintaining the data classification and labeling standards and policies, and ensuring their compliance across the organization.

The CIO is the chief information officer of an enterprise, who oversees and optimizes the use of information technology (IT) to achieve the business objectives and strategy. One of the primary responsibilities of the CIO is to ensure that IT architecture requirements are considered when an enterprise plans to replace its enterprise resource applications (ERAs). ERAs are integrated software systems that support various business functions, such as finance, accounting, human resources, supply chain, etc. IT architecture requirements are the specifications and standards that define how the IT systems and platforms should be designed, developed, deployed, and maintained to support the ERAs and their users. IT architecture requirements include aspects such as performance, scalability, security, reliability, interoperability, usability, etc. The CIO should ensure that IT architecture requirements are considered when an enterprise plans to replace its ERAs, because they can affect the quality, efficiency, and effectiveness of the ERAs and their alignment with the business needs and goals. The CIO should also ensure that the IT architecture requirements are consistent with the enterprise's IT strategy and vision, and that they comply with the relevant policies, regulations, and best practices.
