Scenario
A travel company specializes in providing complete holiday packages to meet customer requirements. There have been instances over the past year where the business has been unable to process holiday bookings due to failure of the IT services. Sales have been lost and the failure has been raised at board level. The IT director has assured the board that the situation will be rectified.
Most holiday bookings are made either by telephone via the company's call centre or through a dedicated website. Both interface with the same back-end booking-processing service. Apart from the call centre and website, the main business services map onto organizational departments and cover: marketing, finance, business operations and central administration.
After some initial investigation within the IT organization, it is clear that the intermittent failures, which were related to a lack of capacity, have occurred during exceptional peak holiday booking periods. The IT organization is not certain when or if these are going to occur in the future. Some booking periods are predictable, such as those associated with promotional offers. Other patterns are totally unpredictable as they often coincide with bad weather being experienced where customers live.
You have been asked how the activities of demand management, based on ITIL practices, can be used to address this issue.
Refer to Scenario
Which one of the following options is the BEST set of actions required to resolve the issue?

• A.Identify the pattern of customer enquiries for holiday bookings and the resulting volume, frequency and location of staff activity. Document these as PBA.
  Gain an understanding of the different roles that are performed by the call centre staff and how these relate to the PBA for the call centre business processes.
  Use this information to identify any shortfall in capacity and create cost estimates of additional resource required to enable the IT services to meet the PBA.
  Discuss the risks associated with failing to meet demand with the business managers. Reach agreement on how to avoid a repeat of the IT failures caused by demand at busy periods.
• B.Identify the pattern of customer enquiries for holiday bookings and the resulting volume, frequency and location of staff activity. Document these as patterns of business activity (PBA) Gain an understanding of the different roles that are performed by staff from all business units and how these relate to the PBA for all business processes.
  Use this information to identify any shortfall in capacity and create cost estimates of additional resource required to enable the IT services to meet the PBA.
  Recommend that, where PBA are very predictable, investment should be made in additional resource.
  Where PBA are unpredictable, the risks associated with railing to meet demand should be discussed with the business managers, and mitigation actions agreed.
• C.Identify and understand the PBA resulting from metrics of all the IT services. Ensure that the volume, frequency and location of service use is taken into account.
  Gain an understanding of how the PBA relate to the use of the IT assets especially the hardware and software that may be the cause of the IT failures.
  Once these activities have been completed, the PBA will be used to plan and implement sufficient capacity to meet all demand at all times.
  Discuss the risks associated with failing to meet demand with capacity management and technical staff. Reach agreement on how to avoid a repeat of the IT failures caused by demand at busy periods.
• D.Immediately implement demand management, document the process and allocate roles and responsibilities.
  The demand manager should initiate an activity to identify and understand user profiles resulting from business use of the IT services. Code the user profiles linking them to the associated business roles.
  Match the user profiles to the IT services and analyze any shortfall in capacity required to meet the business objectives. Create a business case for the additional resource required to exceed the business demand for the IT services to account for unpredictable business activity.
  Work with service portfolio management and financial management to agree on the approval of the investment and initiate the project to acquire all the additional resources.

Scenario
A company provides an internet-based gift delivery service which is highly dependent upon IT services provided by the internal IT organization. A year ago the customer payments service that supports the gift ordering website regularly experienced poor availability. The organization hired a service management consultant to assess why the IT services were performing poorly and to rectify the situation.
As part of the solution, the consultant implemented service level management and adopted the role of interim service level manager. Service level agreements were negotiated with the business and agreed. The necessary underpinning agreements were negotiated and put in place. Regular monitoring and reporting was implemented. Monthly service review meetings with the business unit managers were established to discuss IT service performance and any issues and improvements. Within a year of the start of the initiative the gift ordering website IT service was performing at 98.7% availability, a significant improvement.
This month's service review meeting was attended by the chief executive officer (CEO) after concerns were expressed about the most recent availability figure for the customer payments service, which was 94%. This covered the period which included one of the traditionally most popular gift ordering times. The consultant stated that the poor availability was almost entirely due to an incident that occurred during one of the busiest periods and. as a result, the overall monthly availability percentage was low. Initial investigation has shown that the service desk used the SLA to designate the incident as a 'Priority 2'. This was however lower than the 'Priority 1" the business believed the incident should have been. The subsequent delay in restoration of the service meant some customer orders were lost.
The CEO reminded the consultant that a repeat of such an incident would not only have a major effect on monthly revenues but also seriously affect the company's reputation. The consultant agreed that this was unacceptable and committed to review this issue and report back to the CEO.
Refer to Scenario

• A.The issue is clearly a breakdown in understanding regarding the critical business periods and the matching of these to the availability targets in the SLAs. The SLM should agree with the business managers to set up a SIP to investigate the issue. The SLAs should be reviewed with the business to ensure that they match with the business needs and, if necessary are updated. Review and update any underpinning agreements as necessary to ensure that they support the targets in the SLAs.
• B.The issue is with the service desk and its incorrect interpretation of the SLA and failure to escalate the issues. The SLM should agree to set up a SIP for the service desk. The operational level agreement (OLA) with the service desk should be reviewed to ensure that it underpins the SLAs. The SIP should include the retraining of the service desk staff. A complete review of the service desk tools should ensure that they can be used to prioritize incidents correctly by passing through targets agreed into the priority matrix of the toolset.
• C.The SLM should conduct an investigation by reviewing incidents and problems. Ask the IT service desk and support staff what ideas they have to resolve the issue. Review the impact on all other SLAs. OLAs contracts and procedures. Review the maturity associated with the service level management process and take steps to improve this process if necessary. Create a SIP with an associated business case for presentation to the chief executive officer (CEO).
• D.The SLM should agree with the business managers to set up a service improvement plan (SIP) to address the issue. Differing views relating to the cause of the low availability mean it should be investigated thoroughly to establish whether the slow restoration of service was due to a lack of understanding by the service desk, incorrect service level targets in the SLA or simply that, owing to the type of failure, restoration was always going to take that length of time. Appropriate action can then be taken to rectify the issue.
