Which statement best expresses the difference in purpose between service level management and change enablement in ITIL 4?
- AService level management moves changed components into the live environment, while change enablement makes the resulting features available to users.
- BService level management authorises changes after assessing their risk, while change enablement negotiates the targets recorded in service level agreements.
- CService level management sets clear business-based targets for service performance and assesses delivery against them, while change enablement maximises successful changes by assessing and authorising them. Correct
- DService level management protects the confidentiality and integrity of service data, while change enablement restores normal operation after an interruption.
Why A is wrong: This is tempting because both sit near the delivery of change, but moving components to live is deployment management and making features available is release management, so neither half describes the two named practices.
Why B is wrong: This swaps the two purposes, which appeals to a candidate who knows both practices exist but not which does what; authorising changes is change enablement and agreeing targets is service level management.
Why C is correct: This is correct: service level management's purpose is setting and monitoring agreed, business-based service targets, while change enablement's purpose is maximising successful changes through risk assessment and authorisation.
Why D is wrong: This is attractive because both clauses name genuine ITIL concerns, but protecting data is information security management and restoring normal operation is incident management, so neither describes service level management or change enablement.
