1. A non-transitory computer readable storage medium including instructions executed by a computer system to perform a method for simulating and analyzing one or more scenarios for a communications network service to be deployed, the method comprising: receiving business and technology changeable parameters describing the communications network service to be deployed; simulating the service using the business and technology changeable parameters, a base case model, a network cost model, and a bandwidth model to determine at least one candidate solution for deploying the service, wherein the base case model, the network cost model, and the bandwidth model each include a model parameter intradependent on a corresponding model parameter in at least one of the base case model, the network cost model, and the bandwidth model, wherein the at least one candidate solution includes business and technology sub-solutions; accessing real-time information pertinent to the model parameters; assigning values to the model parameters based on the real-time information; and generating an analysis of the at least one candidate solution to evaluate an impact of the changeable parameters, wherein generating the analysis includes generating the analysis of the at least one candidate solution across multiple domains of the service, and each domain is a logical sectioning of the service, and each domain is associated with a different technology for providing the service, and changes in one domain impact changes in another domain.
