Automated system and method for service and cost architecture modeling of enterprise systems

A computer system for modeling information system architecture of an enterprise, comprising:

• a business process design module for describing a plurality of business processes and defining a set of corporate requirements and business service requirements for each business process;
• a construction module responsive to the business process design module, the a construction module responsive to the business process design module and constructing a multi-layer mathematical model of an information system architecture of the enterprise, the layers of the multi-layer model comprising a business layer, an application layer, and a technology layer, and the construction module modeling performance metrics for each layer of the multi-layer model including modeling cost, quality of service and throughput;
• and
• a situation-remedy table formed based on the modeled performance metrics, the table enabling analysis of the enterprise information system architecture.

Computer apparatus for modeling enterprise information system architecture, comprising:

• means for receiving a business process design, the business process design describing a plurality of business processes and defining a set of business service requirements for each business process;
• means for constructing a multi-layer mathematical model of a system architecture supporting the business process design, the layers of the multi-layer model comprising a business layer, an application layer, and a technology layer, each layer having cost, quality of service and throughput dimensions;
• means for modeling performance metrics for each layer of the multi-layer model of the system architecture;
• means for comparing the modeled performance metrics with the set of business service requirements for each business process;
• and
• means for modifying the system architecture in a manner improving unacceptable performance metrics of one or more business processes that do not satisfy the set of business service requirements defined for them.

An article of manufacture, comprising:

• a computer-readable medium;
• a set of computer operating instructions embodied on the medium for modeling an enterprise information system architecture, including instructions for:
• providing a business process design, the business process design describing a plurality of business processes and defining a set of corporate requirements and business requirements for each business process;
• constructing a multi-layer mathematical model of a system architecture supporting the business process design, the layers of the multi-layer model comprising a business layer, an application layer, and a technology layer;
• modeling performance metrics for each layer of the multi-layer model of the system architecture, including cost, quality of service and latency;
• and
• from said modeled performance metrics, producing business ephemeris for analysis of the enterprise information system architecture.
