1. An information management system for producing at least one standard bill of resources based on a plurality of bills of resources, where each of the plurality of bills of resources each include a list of resources to be utilized in performing a procedure, the system comprising: a general purpose computer system, including: storage means for storing information related to the plurality of bills of resources; processing means for processing instructions related to producing the at least one standard bill of resources; display means for presenting the at least one standard bill of resources in a human perceptible format; and input means for receiving user input related to producing the at least one standard bill of resources; information management software executed by the general purpose computer system, including: node software objects, each providing a health-care information management function, including: a clinical pathway node software object for selectively creating, managing, and maintaining user-defined, user-configurable clinical pathway module software objects adapted to function with the clinical pathway node software object and representing provider-specific procedural templates of the information related to the bills of resources, the clinical pathway module software objects including: resource software objects, corresponding to resources to be used in providing health care services, the resources listed in the plurality of bills of resources; and container software objects for containing software objects having at least one common characteristic; a case management node software object for selectively creating, managing, and maintaining a user-defined, user-configurable case management module software object adapted to function with the case management node software object from the clinical pathway module software object, the case management module software object representing a selected clinical pathway module software object as modified to reflect a prospective patient-specific case, and containing patient-specific information, and adapted to receive additional patient specific information; and a bill of resources standardization review node software object for selectively creating, managing, and maintaining at least one user-defined, user-configurable model module software object adapted to function with the bill of resources standardization review node software object and the case management module software object, the model module software object representing the case management module software object as modified by at least the patient-specific information to reflect a historical patient-specific case by: selecting selected bills of resources from the plurality of bills of resources; developing models corresponding to the selected bills of resources, the models including values which correspond to a number of units of given resources from the selected bills of resources; manipulating the models mathematically to highlight similarities and dissimilarities of defined characteristics in the models; expressing the manipulated models in a format in which a relative position of each of the manipulated models may be determined, the relative position of each of the manipulated models reflecting the degree of similarity or dissimilarity to the other manipulated models; analyzing the selected bills of resources based upon the expression of the manipulated models; and producing the at least one standard bill of resources based on the analysis of the selected bills of resources.
