Reference Modeling involves the customization and validation of any or all of the reference models to jump-start the enterprise architecture development process.

Proact has developed an extensive library of reusable Reference Models ranging from Retail, Manufacturing, and Service Industries to Governments and Military Institutions that are provided with the initial license of the Proact Toolkit. Reference Modeling leverages the appropriate reference models to define the nature of the business and establish the context for all enterprise architecture activities.

The Reference Models are used to "focus" the enterprise architecture activities. The Proact Toolkit is extremely flexible in applying various model-based planning methods to meet the specific organizational needs, priorities, and timeframes. Enterprise Architecture Programs may range from a major enterprise-wide target architecture development (such as a major systems and technology overhaul) to a very focused opportunity based on improving a specific area of operations.
