Pinaki Ghosh has mostly worked as an Enterprise and Information Systems Architect for the last 9+ years but most of it was from the from the business side. He enjoys the art of simplifying/decomposing complex structure without losing the characteristics produced by the complexity. It is the interaction of the various elements in a system which interestshim most. The non-linear behavior of systems often creates unpredictable future which is challenging. The idea is to find the few elements which are going to interact most predictably, trying to change / control the behavior of the whole system. Once you find these few elements then the analytics is done pair-wise.

He has also implemented 2 ERP system (End to End) and at this point he is involved with the upgrade of one of the world's largest ERP system. This has moved his focus to EA framework and he is trying to use the EA framework as the guiding tool for the implementation process.

Pinaki Ghosh has also published about a dozen conference and journal papers.

Introducing Enterprise Architecture Framework at The Dow Chemical Company - From Frameworks to Objects

The Dow Chemical Company introduced the EA Framework as a part of its Enterprise Architecture Development Methodology (similar to IEEE 1471 2000) in June 2007. From that time onwards the Dow EA framework has matured through rationalization and governance process to garner user acceptance.

The Dow EA framework, derived from TEAF, is very similar to the TOGAF framework and uses the same Meta-model. The framework is supported by multiple streams of architecture description documents and the models are supported by federated and enterprise objects. Dow Chemical has developed process methodology and taxonomy to create and maintain model libraries and object libraries while moving towards modeling standard like BPMN, BPEL etc. The libraries with well developed taxonomy are supported and populated by the Project Delivery Methodology (PDM), which is Dow's in-house process for project management. Inside the framework Business Services are designed to be supported by Application and Technical Services from service libraries which are also part of the EA framework.

The entire EA life-cycle process at Dow Chemical includes development, maintenance and governance of various artifacts and documents supporting "architecture descriptions" including tenant design, security, composite application framework, service libraries, data models, business process models and corresponding objects. The re-usability of objects has been the key to drive systems architecture connecting business, application, data and technology.

Audience:-

• All EA practitioners who are implementing EA or will implement EA in the future

Key takeaways:-

1. EA Framework implementation
2. Re-use of Objects in EA Modeling
3. Systems design through Business, Application, Data and Technical modeling
