Which process is primarily supported by the analysis of Patterns of Business Activity (PBA)?

Availability Management focuses on ensuring services meet agreed availability and reliability targets, and does not use PBA analysis as a primary input to its activities.

Demand Management is responsible for understanding and influencing customer demand for IT services, and PBA analysis is its core technique for achieving this. By analyzing how business activity patterns vary - for example, peaks during month-end processing or seasonal spikes - Demand Management enables the service provider to predict demand fluctuations and align capacity and resource supply accordingly, preventing over- or under-provisioning.

Financial Management deals with budgeting, accounting, and charging for IT services, and is not primarily concerned with analyzing business activity patterns to forecast or shape service demand.

Service Level Management negotiates, documents, and monitors service level agreements and service achievements, but does not primarily rely on PBA analysis to fulfill its purpose.
