Identify resource utilization needs
The operational model should be analyzed to understand how resource availabil-
ity impacts the operational or business process. The focus should be on computing 
environment resources, which involve any physical or virtual component of limited 
availability. Within the operational model, activities that are performed in parallel 
may contend for available resources. Contention for resources results in process 
delays that can be alleviated by increasing the availability of resources. When 
resources are limited, then scheduling mechanisms may be needed to ensure that 
high-priority functions are given access to resources before lower-priority functions.
At the operational or business process level, the resource utilization analysis is 
useful in determining the resources incorporated into the computational environ-
ment. At the software product level of analysis, the availability of resources may 
constrain data processing flow and may identify the need to modify the computing 
environment definition to incorporate additional computing equipment.
