What Is IT Capacity Planning?
IT capacity planning is the process of balancing current IT resources against forecasted needs to ensure optimal productivity and efficiency. It’s a vital part of the broader ITIL capacity management process and involves:
- Ensuring resources (servers, networks) handle expected and unexpected loads.
- Implementing deployment and management systems.
- Defining procurement and approval systems.
- Planning for capital expenditure.
This process is typically managed by a technical role, like an engineer, while generalized planning is handled by resource managers, project managers, or capacity planners. Both approaches are essential for sustainable growth in a professional services environment.
“The more technical and larger you get, the more expectations there are. High aspirations need reliable systems and efficient processes to ensure that the level of quality remains constant as the business grows.” — Brendon Nicholas, Co-Founder and Technical Director at DotDev
Types of IT Capacity Management
IT capacity planning can be categorized into:
- Strategic vs. Tactical Planning: Strategic planning involves long-term decisions, while tactical planning focuses on short-term resource availability.
- Resource-based vs. Service-based Planning: Resource-based planning focuses on individual IT resources, while service-based planning looks at IT service performance and availability.
Both approaches support successful capacity planning, balancing short-term, medium-term, and long-term needs, and aligning with overall agency management processes.

How To Create an IT Capacity Plan?
Creating an effective IT capacity plan involves:
- Assessing Current Infrastructure: Measure the workload characteristics of each component (web server, database server, network).
- Forecasting Future Performance: Predict future needs based on traffic growth, past performance, and user expectations.
- Deployment and Management: Use industry-proven tools and techniques to manage capacity.
A capacity plan should be flexible and adaptable to changes in agency operations or technological trends.
