In the previous chapter, we learnt what Capacity Management is. In this chapter, we are going to take a look at the goals, purpose and objectives of Capacity Management.
Goals of Capacity Management:
The goal of the Capacity Management process is to ensure that there are sufficient IT resources to satisfy the current and future needs of the business. This is done as a delicate balance between:
• Supply versus demand - Sufficient resources must be available to meet the business demand and maintain service levels. This can be helped by influencing demand (through the Demand Management process) to make the most effective use of resources and by tuning and optimizing current resources.
• Costs versus resources – Cost Spent on resources must be justified by business need and resources must be used efficiently. This can be helped by considering the cost benefits of newer technology.
Purpose of Capacity Management:
The purpose of Capacity Management is to provide a focal point and management responsibility for all capacity and performance-related activities in respect of both resources and services.
Objectives of Capacity Management:
The primary objectives of the Capacity Management process are as follows:
• Produce and maintain a Capacity Plan, assessing the impact of changes on the plan and on the performance of services and resources.
• Contribute to meeting service levels by managing the capacity and performance of services and resources.
• Provide advice and guidance on all capacity and performance-related activities, assist with the diagnosis and resolution of related Incidents and Problems and propose proactive performance improvements where these are cost-justifiable.
