The correct answer is B. Establish a formal change management process. A formal change management process best complements the CIO's governance mandates by controlling the highest-risk activity in IT operations - unmanaged changes - which is a primary driver of unplanned system downtime.
Question
The Chief Information Officer (CIO) is focused on improving IT governance within the organization to reduce system downtime. The CIO has mandated that the following improvements be implemented:
- All business units must now identify IT risks and include them in
their business risk profiles.
- Key controls must be identified and monitored.
- Incidents and events must be recorded and reported with management
oversight.
- Exemptions to the information security policy must be formally
recorded, approved, and managed.
- IT strategy will be reviewed to ensure it is aligned with the
businesses strategy and objectives. In addition to the above, which of the following would BEST help the CIO meet the requirements?
Options
- AEstablish a register of core systems and identify technical service owners
- BEstablish a formal change management process
- CDevelop a security requirement traceability matrix
- DDocument legacy systems to be decommissioned and the disposal process

Why each option
A formal change management process best complements the CIO's governance mandates by controlling the highest-risk activity in IT operations - unmanaged changes - which is a primary driver of unplanned system downtime.
Establishing a register of core systems and technical service owners improves accountability and ownership clarity but does not directly control the risk of outages caused by poorly managed changes.
Uncontrolled changes are a leading cause of system outages; a formal change management process requires documentation, impact analysis, testing, approval gates, and rollback plans before any change is applied to production systems. This directly supports the CIO's downtime reduction goal and reinforces the broader governance mandates by adding structured oversight and management visibility to change activity across all business units.
A security requirements traceability matrix tracks security controls against compliance requirements and is primarily a compliance assurance tool, not an operational governance mechanism for reducing downtime.
Documenting legacy systems for decommissioning is a bounded, one-time planning activity that does not provide the ongoing governance controls the CIO needs to address continuous operational risks.
