Which TWO are key activities of Capacity and Performance Management?
Forecasting future demand for services is a critical activity within capacity and performance management, specifically for proactive capacity planning. By analyzing historical trends, business plans, and anticipated growth, organizations can predict future resource requirements for IT services and their underlying components. This foresight enables the timely acquisition, provisioning, or scaling of infrastructure and applications, ensuring that sufficient capacity is available to meet evolving business needs without costly over-provisioning or detrimental under-provisioning.
Why this answer
Option C (Forecasting future demand for services) is correct because Capacity and Performance Management must anticipate future workload and resource requirements so that services continue to meet agreed performance targets as demand grows. Option E (Monitoring current service performance) is correct because it provides the baseline data on utilization, throughput, and response times needed to compare actual performance against targets and to feed accurate forecasting. Together, these activities form the core iterative cycle of measuring present performance and predicting future capacity needs.
Option A (Defining service level targets) belongs primarily to Service Level Management, which negotiates and agrees SLAs rather than performing capacity analysis. Option B (Managing the IT service desk staffing levels) is a workforce/resource management activity, not a capacity management activity for IT services. Option D (Managing service availability) is the domain of Availability Management, which focuses on uptime and reliability rather than capacity and performance.
Exam trap
ITIL4F often tests the confusion between related practices — candidates mistakenly assign SLA definition to Capacity Management when it actually belongs to Service Level Management, or confuse availability with capacity.
