Scenario
A clothing manufacturer has made a decision to supplement factory-based retail outlets by opening a series of stores at out-of-town shopping malls.
The internal IT organization provides support to many mission-critical business systems for both the manufacturing and retail operations. It must increase its portfolio of services and service options to meet the planned new expansion. Typically, the business is subject to seasonal patterns of demand, which recently have begun to exceed the capability of some of the IT services. This has led to periods of poor performance of some of the critical systems and therefore to degraded service quality. In periods of minimal demand, there is a surplus of capacity and performance is optimal.
There is concern that the additional business demand from the new stores will exacerbate these service performance issues.
The board of directors, made up of representatives from each business unit, has asked for a review of the business supply and demand issues currently being faced by the IT organization. Many service management processes have been implemented including service portfolio management and capacity management. However, IT does not have a demand management process.
Additionally, performance levels on many of the supporting services have remained unchanged for the past 3 years, even though some may now be less relevant to the overall performance of the critical services.
Refer to the Scenario.
The review of the supply and demand issues concluded that the implementation of a demand management process could help the IT organization address the issues. Which one of the following options provides the BEST solution to both the problems currently being faced and those related to the proposed expansion?
A. The service portfolio should be reviewed and the business unit's cumulative service usage should be reviewed, monitored and analyzed.
Work with the business to develop short-term measures to manage demand for the IT services, such as delayed or batch processing of retail transactions.
Service levels should be reviewed to take into account changes to supporting service performance targets and, where applicable, agreements should be updated through change management.
B. The service portfolio should be reviewed and an analysis carried out of each business unit's requirements in order to understand their patterns of business activity (PBA) and corresponding usage of the IT services.
Differentiated service offerings should be developed to match PBA; this will make better use of available IT resources. Supporting service performance targets should be amended to reflect these changes.
Work with business relationship management and capacity management to develop long term plans to meet the extra demand resulting from the company's expansion plans.
C. The service portfolio should be reviewed and an analysis carried out of each business unit's requirements to understand their current usage of the IT services and where seasonal variations lead to fluctuations in usage.
Discussions should take place with the business units to impose limits within specific time periods for each business unit's usage of IT services.
Work with business relationship management and capacity management to develop long term plans to meet the extra demand resulting from the company's expansion plans.
D. An analysis should be carried out of each business unit's patterns of business activity (PBA), and appropriate services for each business unit selected from the service catalogue.
In conjunction with the finance department, a revised cost model should be introduced to allow for the fluctuation in usage and costs.
Differential charging should be introduced to address the issues of service quality.
