Exigen Process Backbone

In addition to the traditional software implementation capabilities, Exigen Services will often recommend leveraging the Exigen Process Backbone (EPB) software, developed in-house and used in conjunction with Service Oriented Architecture (SOA) and Model Driven Approach (MDA).

Following are some of the existing services part of the EPB platform:

  • Integration Services will be used to overlay the system to create an abstract view of data
  • Business Object Model (BOM) describes the business objects identified for the final solution
  • Decision Services will be used as a repository for business logic
  • Process Control Services provide for real-time visibility, control and streamlining of business processes
  • Workspace Services presents functions to end-users via an advanced user interface

When Exigen Services and the customer choose to pursue legacy transformation leveraging EPB, the transformation methodology is tailored into the following phases:

Phase 1:
Each legacy system is analyzed and deconstructed into business functions.
Phase 2:
Each business function is mapped into layers, up to five layers in total, and described as models. These are, from lowest to highest layer: Data, Data-Related Logic (Business Objects), Business Logic, Business Process Logic, and User Interface
Phase 3:
Each To-Be process is analyzed for re-use of business functions
Phase 4:
A composite application is created from the legacy business logic and data model using a Model Driven Architecture (MDA) and Services Oriented Architecture (SOA).
  • MDA enables rapid configuration and creation of business objects, logic, GUI and legacy mapping
  • SOA enables rapid assembly or quick modification of processes
Phase 5:
Once the requirements for the missing functionality have been determined, they are either configured or built, using Exigen Process Backbone technology
Phase 6:
Deployment proceeds “one process at a time.” A process-phased deployment enables each process to be tested in parallel, with legacy and new functionality running side-by-side and the outcome compared. If failure should occur, the system can instantly be rolled back to the legacy function.

Below is a graphical depiction of phases 1-5 of Exigen’s methodology.

Some benefits to engaging Exigen for legacy transformation include:

  • Updates no longer need to be applied directly to legacy systems since the old functionality in the legacy system is “frozen,” and new functionality leverages the old, saving clients money in the cost of maintenance for these systems.
  • Payment for a complete replacement of the system is not necessary, only for the new features required. Because you better leverage existing legacy systems, you may only have to deploy the new required functionality.
  • Risk aligned with value; rapid value achieved for each new feature.
  • Faster time to market due to:
    • Industry-knowledgeable staff resources means the learning curve for business processes in our target industries is not steep.
    • Employees are very experienced using the newest technologies and industry-standard processes to create high-quality products and solutions.
    • Commercial-ready software available, meaning Exigen Services does not have to rewrite everything.
    • Process and Methodology
      • Exigen Services has created over 2000 use cases, available to be leveraged for your project
      • Exigen Services’ SOA and MDA architectures deliver future-proof solutions, with the ability to deliver innovation rapidly, incrementally and at the lowest cost
      • Strong transformational skills—data and people migration skills as well as knowledge transfer.
