Introduction

A key process in the Service Design life cycle phase.

Goals & Objectives

To ensure capacity is consistent with existing services and able to match future services (capacity plan)

Terminology

• CMIS: Capacity Management Information System
• Capacity Plan: A plan to ensure future requirements can be matched
• Capacity Components: A breakdow of a service provides capacity components (Capacity Component Plan)
• Modeling: Predicting behaviour of systems under different circumstances.
• Baselining: Present day level for later comparison
• Trend Analysis: For future relevance, trends affecting future utilization of capacity components
• Analytical model: Mathematical models representing certains components eg. Amount of memory being used in a system
• Simulation modeling: For predicting the effects of changes to systems.

Roles

Capacity Manager: many ongoing activities implementing various sub-processes to always be one step ahead of capacity demand for present day and future services.

Scope

The activities of the Capacity Management process will interface:

• Demand Management
• All other Service Design key processes

Activities

• To obtain accurate business information on strategies for future services
• To have forecasted budget plans
• To review all agreements
• Trending and modeling
• Capacity performance, erviews and reports

Interfaces
