In one aspect, a method of instructing at least one operator in a best practices implementation of a process for managing resource capacity in an information technology (IT) environment is provided. The method comprising providing instructions to the at least one operator to perform acts of: (A) creating at least one model of at least some aspects of the IT environment; (B) analyzing the at least one model to determine cost information relating to the modeled IT environment; (C) applying at least one simulated use condition to the at least one model; (D) analyzing performance of the at least one model under the at least one simulated use condition to determine information relating to at least a utilization of resources in the modeled IT environment and to determine resources in the modeled IT environment that create performance bottlenecks in the modeled IT environment; and (E) modifying at least one aspect of the at least one model impacting resource capacity based on the information determined in (B) and/or (D).
