Abstract

A method for integrating business functions performed by different application systems comprising generating a business model, based upon said application systems, generating a logical model, based upon said business model, generating a physical model, based upon said logical model, designing an infrastructure, based upon said physical model, assembling the infrastructure, testing the infrastructure, and implementing the infrastructure.

Claims

1. A method for integrating business functions performed by different application systems, comprising:

generating a business model, based upon said application systems;

generating a logical model, based upon said business model;

generating a physical model, based upon said logical model;

designing an infrastructure, based upon said physical model;

assembling the infrastructure;

testing the infrastructure; and

implementing the infrastructure.

2. The method for integrating business functions performed by different application systems according to claim 1, wherein said business model comprises:

a process domain model;

a information domain model;

a system infrastructure model; and

an operations model.

3. The method for integrating business functions performed by different application systems according to claim 1, wherein said logical model comprises:

a logical process event model;

a logical data model;

a logical infrastructure model; and

an operations architecture.

4. The method integrating business functions performed by different application systems according to claim 1, wherein said physical model comprises:

a physical process event model;

a physical data model;

a physical infrastructure model;

an operations management model; and

a test strategy.

5. The method integrating business functions performed by different application systems according to claim 1, wherein designing an infrastructure comprises:

generating an integration services design;

generating a data transformation design;

generating a performance test plan;

generating a production readiness test plan; and

generating an integration test plan.

6. The method for integrating business functions perform-ed by different application systems according to claim 1, wherein assembling the infrastructure comprises:

building and testing integration components;

developing operations procedures; and

building test scenarios, scripts and cases.

7. The method for integrating business functions performed by different application systems according to claim 1, wherein testing the infrastructure comprises:
