What is the primary focus of business capacity management?

This describes Component Capacity Management, which monitors and predicts the performance and utilization of individual IT infrastructure components such as servers, disks, and networks.

Reviewing capacity supplier agreements and underpinning contracts falls under Supplier Management, not Business Capacity Management.

This describes Service Capacity Management, which is responsible for the end-to-end performance and capacity of live operational IT services as experienced by users.

Business Capacity Management (BCM) is the Capacity Management sub-process concerned with translating future business plans and growth forecasts into IT capacity requirements. Its primary goal is to ensure that future business needs for IT services are quantified, designed, planned, and implemented in a timely manner before demand arrives. This forward-looking focus distinguishes BCM from Service Capacity Management, which handles current live service performance, and Component Capacity Management, which handles individual infrastructure elements.
