Understanding customer usage of services and how this varies over the Business Lifecycle is part of which process?

Service Portfolio Management governs which services are offered, retired, or developed - it does not focus on analyzing how customers consume services over time.

Service Level Management negotiates and monitors service level agreements and targets, not customer usage patterns across the business lifecycle.

Component Capacity Management focuses on the performance and capacity of individual infrastructure components, not on business-level usage patterns or lifecycle trends.

Demand Management is responsible for understanding Patterns of Business Activity (PBA) and customer usage of services across the business lifecycle. It analyzes how demand fluctuates and works with Capacity Management to ensure supply aligns with demand. This process directly informs capacity planning and service investment decisions.
