Scenario
A flower delivery company introduced ITIL-based service management processes 12 months ago.
One major benefit of the associated service improvement initiatives was that the service availability of the business critical on-line flower ordering IT service increased from 97% to 98.9% over the last quarter. This exceeds the service availability target of 98.5%. Last month, reports were circulated showing the availability improvement.
The service level manager is chairing a service review meeting to review the progress and report upon this achievement. The customer managers acknowledge the improvement but despite the reports of improved service availability, a major service outage occurred during the busiest week of the year when over 25% of the annual business revenue is normally earned. Although IT dealt with the outage satisfactorily, the loss of revenue and credibility in this mission critical, high-visibility trading period are serious concerns. The customer managers are concerned that the reporting does not seem to reflect this or their actual perception of the service.
Agreement is reached at the meeting to address two primary concerns:
1. Service availability targets for the mission critical periods are to be revised.
2. Amended and more representative business reports are to be produced.
Refer to the Scenario.
Which one of the following options will BEST ensure that the primary concerns related to the revision and reporting of targets are addressed?

• A. Meet with the customer managers to conduct a thorough review of all services and document all revised service level requirements (SLRs), ensuring that business impact and seasonal variations are taken into account. The SLRs should be transformed into a balanced scorecard of service targets with a dashboard for reporting purposes. Mechanisms should be agreed and implemented to collect, analyze and report against the agreed service targets using the change management process. Reports should be circulated to customer managers five working days in advance of service review meetings.
• B. Review the requirements for service availability against the data collection and measurement currently provided by the IT teams. Design availability metrics and controls to report any variances at the monthly service review meetings, as well as how these variances will be addressed in the future. Internal IT staff and a customer manager will attend the service review meetings. All changes have to be agreed in the service review meetings before any actions can be performed, thus forcing the customer to come to the meetings and reach agreement before any improvement work or change can occur.
• C. Determine what information each IT team can provide regarding the collection and reporting of component availability. Implement revised mechanisms for the analysis, calculation and reporting of service availability. Ensure that event management is implemented to trigger alerts in response to availability issues. This will allow for reactive measures to be introduced so that, if services fail to meet their availability targets, proper actions can be taken to mitigate future failures.
• D. Meet with the customer managers to review and document their availability requirements, ensuring that business impact and seasonal variations are taken into account. Review the monitoring and measurement mechanisms and ensure that they can measure both component and end-to-end service availability. Agree the revised service availability reporting requirements with the customer. Agree and revise service level agreements and operational level agreements as necessary and implement any changes to the monitoring and reporting mechanisms using the change management process.
