Explanation: 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.
