Which metric is the most effective indicator of IT governance success?
Governance succeeds when IT spending produces measurable business outcomes. Alignment between IT investments and realised business value directly evidences that governance decisions steer resources toward strategic objectives, unlike operational metrics such as uptime or ticket volume.
Why this answer
IT governance exists to ensure IT delivers value aligned with business strategy, so the most effective success indicator is the degree to which IT investments align with and produce realized business value. This metric directly measures the governance objective of value delivery and strategic alignment, which COBIT and ISO/IEC 38500 both identify as the primary governance outcomes. Operational metrics like cost, schedule, or patch counts are inputs or enablers, not indicators of governance success.
Exam trap
CGEIT often tests the difference between efficiency metrics (cost, schedule, patch counts) and effectiveness metrics (alignment, value realization), luring candidates toward operational numbers that feel measurable but miss the governance point.
How to eliminate wrong answers
Option B is wrong because total cost of IT hardware and software maintenance is a cost-efficiency measure, not a governance success indicator — low cost with poor business alignment is still governance failure. Option C is wrong because on-time project completion measures delivery discipline, not whether the projects delivered value or aligned with strategy; many on-time projects fail to realize benefits. Option D is wrong because patch counts measure operational security hygiene, a management activity, not the strategic alignment and value realization that governance is judged on.
