This paper formally defines the Ratio Modeling technique as set of steps enabling you to quickly perform low confidence capacity predictions, which are required when budgeting hardware, assessing technical risk, validating alternative technical architecture designs, sizing packaged applications, and predicting production system capacity requirements. This technique enables you to define the relationship between process categories (e.g., batch processes) and a specific system resource (e.g., CPU). The Ratio Modeling technique has been used and validated by capacity planners and technical architects since 1996. This papers details step-by-step how you can determine ratio categories, calculate the ratios, make capacity predictions using the ratios, and validate both the ratios and the resulting predictions on your production system.
