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.

This is because before decommissioning an IT system, it is most important to ensure that the data stored on the system is handled according to the retention policy of the organization. A retention policy is a document that specifies how long and where different types of data should be kept, archived, or deleted, based on the business, legal, and regulatory requirements. Assessing compliance with the retention policy can help to avoid data loss, leakage, or breach, as well as comply with the applicable laws and regulations.
Assessing compliance with environmental regulations is not the most important action, as it is a secondary consideration for decommissioning an IT system. Environmental regulations are rules that govern the disposal or recycling of IT equipment and materials, such as batteries, cables, or monitors, in order to protect the environment and human health. Assessing compliance with environmental regulations can help to reduce the environmental impact and waste of IT resources, as well as avoid fines or penalties. However, assessing compliance with environmental regulations does not address the primary concern of data management and security.
Reviewing the media disposal records is not the most important action, as it is a subsequent step after assessing compliance with the retention policy. Media disposal records are documents that provide evidence and verification of the proper disposal or destruction of IT media, such as hard drives, tapes, or disks, that contain sensitive or confidential data. Reviewing the media disposal records can help to ensure that the data on the IT system is erased or overwritten in a secure and irreversible manner, as well as comply with the audit and accountability requirements. However, reviewing the media disposal records does not provide a comprehensive assessment or guidance for data retention and compliance.
Reviewing the data sanitation records is not the most important action, as it is a similar step to reviewing the media disposal records. Data sanitation records are documents that provide evidence and verification of the proper sanitation or cleansing of data on an IT system, such as deleting, encrypting, or masking data that is no longer needed or relevant. Reviewing the data sanitation records can help to ensure that the data on the IT system is protected from unauthorized access, disclosure, modification, or destruction, as well as comply with the privacy and confidentiality requirements. However, reviewing the data sanitation records does not provide a thorough assessment or guidance for data retention and compliance.

When an IT governance committee is reviewing its current risk management policy due to increased usage of social media within an enterprise, the first task should be to initiate an assessment of the impact on the business. This assessment will provide a comprehensive understanding of how social media usage affects various aspects of the business, including productivity, security, data privacy, and compliance with existing policies and regulations. Understanding the business impact will inform the committee's decisions on any necessary policy adjustments or controls to mitigate potential risks associated with social media usage. While reviewing current usage levels, blocking access, and reassessing BYOD policies are relevant considerations, they should be informed by an initial assessment of the business impact to ensure that any actions taken are aligned with the enterprise's strategic objectives and risk tolerance.
