3. Service Quality: Ensuring that the IT services meet the required performance standards and are available when needed.

4. Risk Management: Identifying and mitigating risks related to the capacity of IT services.

5. Future Proofing: Planning for future business growth and technological changes to ensure the IT infrastructure can adapt.

### Key Activities of Capacity Management


1. Capacity Planning: This involves forecasting the demand for IT services and resources and planning for the required capacity to meet that demand.

2. Capacity Analysis: Analyzing current capacity against the demand to identify any shortfalls or excesses.

3. Capacity Monitoring: Continuously monitoring the usage of IT resources to ensure they are performing within acceptable parameters.

4. Capacity Optimization: Making adjustments to the IT infrastructure to improve its efficiency and effectiveness.

5. Capacity Reporting: Providing regular reports on the capacity of IT services to stakeholders.
