IT capacity is the ability of an IT system or network to handle the current and future workload and performance demands. IT capacity can be affected by various factors, such as the numberand type of users, applications, devices, data, transactions, etc. IT capacity management is the process of planning, monitoring, and optimizing the IT resources to ensure that they meet the business needs and objectives. IT capacity management can help prevent issues such as system slowdowns, outages, errors, or failures, and improve the efficiency, reliability, and security of the IT system or network. One of the IT key risk indicators (KRIs) that provides managementwith the best feedback on IT capacity is the trends in IT resource usage. IT resource usage is the measure of how much of the IT resources, such as CPU, memory, disk, bandwidth, etc., are being consumed by the IT system or network. Trends in IT resource usage can help monitor and analyze the changes in the IT capacity over time, and identify the patterns, peaks, and bottlenecks in the IT resource consumption. Trends in IT resource usage can also help forecast the future IT capacity requirements, and plan for the appropriate IT resource allocation, optimization, or expansion. Trends in IT resource usage can provide management with valuable information on the current and potential IT capacity risks, and support the decision making and risk response for IT capacity management. References = Integrating KRIs and KPIs for Effective Technology Risk Management, p. 3-4.
