ITIL 4 defines capability levels based on outcomes and value delivery, with higher levels indicating reliable and effective practices. To assess whether an organization is increasing its deployment management capability by maintaining an effective approach, the key criterion is whether new and changed services and service components are successfully deployed (Option A). This outcome-focused measure directly indicates the practice's reliability and alignment with organizational goals.
Option A (New and changed services and service components are successfully deployed): Correct, as successful deployments are the primary indicator of an effective deployment management practice, reflecting capability maturity in ITIL 4.
Option B (Deployments are supported by relevant competences): Incorrect, as while competences are important, they are a supporting factor, not the primary criterion for assessing capability outcomes.
Option C (Deployments include required technologies and information flows): Incorrect, as having the right technologies is a prerequisite, not a direct measure of deployment success or capability.
Option D (Deployment rules are integrated with policies and rules for changes and releases): Incorrect, as integration with other practices supports deployment but is not the key indicator of capability compared to actual deployment success.
