Presentations

This is the working area for Light EA development. It consist of the following sections which start with what is LEA, explain the fundamental concepts, address planing approach. Elaborate Business Architecture, Alignment Architecture, Cross cutting Architecture and Coherence Architecture. Further apply the EA holistic approach to Enterpirse IT management and the entire enterprise managment


1:What is Light EA?

Instead of architecting a full blown enterprise blueprint, LEA suggest a light approach via the concept of Notional target architecture, Reference archtiecture, Service Orinted Architecture and Segment Architectue to adapt change in time of need. LEA serve both large and small organizaitons.

2:LEA Fundamental

    To learn the fundamental of LEA, it take a human centric, holistic, agile and adaptive EA approach to answer the complex system of enterprise

3:Light EA Planning

    Management include the management of communication, performance, investment, change, project and services

4: Enterprise Topology

EA can not be called EA without seeing the true enterprise big picture. EA topology is a LEA inovation to see the tangible enterprise big picture and articulate EA collaboration from the begining of EA

5: Business Architecture Modeling

The Holistic Business Architecture define organization through the enterprise’s mission, function, processes, organization, location and demand and their relation to structure, connectivity and influence.

High level Business Architecture Example

6:Alignment Architecture

Alignment Architecture is a top down architecture but light. It is a matter for business community to adopt a vehicle but not making vehicle

Notional Application Architecture Example

Notional Data Architecture Example

7: Agility Architecture

Agility architecture is a cross cutting architecture paradigm which include reference models, reference architecture, the engineering of reuse, the engineering of consolidation, the politics of standardization, governance and compliance

8:Coherence Architecture

Coherent Architecture embraces change and helps organizations formulate educated business strategies, make sound investments, and deliver the right solutions -- to the right people, at the right times, and to the right places.


9: EA Governance

Apply the EA holistic framework approach to IT management

10: Enterprise Management

Apply the EA holistic framework approach to every aspect of enterprise managment areas

LEA introduction in the Toolbox for IT by Akshaya Bhatia

Mar 04, 2009

Thanks to Akshaya Bhatia's introduction on LEA in the Toolbox for IT. It is truly a great recognition and encouragement:

Light Enterprise Architecture (LEA) is a pragmatic, innovative, light weight and fast track enterprise architecture model developed and documented by an eminent enterprise architect John Wu.

The LEA immaculately blends cohesive system modeling endeavors encapsulating study of business architecture and analysis of system architecture using appropriate system segmentation by way of an agile approach aiming at development of a business enterprise based on technology alignment with the business.

Although the LEA model borrows some concepts from other well known EA models such as Zachman Framework, TOGAF ( The Open Group Architecture Framework), PRISM (Partnership for Research in Information Systems Management) Architecture Framework, Gartner approach to EA, FEA (Federal Enterprise Architecture)-US etc. , it is, per-se, a pragmatic, innovative and unique approach in many ways owing to it’s emphasis on agility along with mapping technology solutions for maintaining a flexible and strategic thrust on business alignment in sight of continuously evolving business enterprise.

Just like most of the popular EA models in vogue, the LEA model also caters in extenuating the complexity involved in system design process so as to make an appropriate use of technology in implementation of business processes such that business goals of the enterprise are fulfilled, albeit with a relatively less emphasis on building from scratch and more emphasis on building upon the existing framework by application of agile approach and characteristically looking for a cross cutting approach based on loose coupling.

Key idea is to follow a structured approach by identifying commonality (patterns) amongst the attribute values of the sub-systems , deciphering the bottlenecks or business performance gaps among the business segments and plugging in the gaps by visualizing through business plus data plus application architectures.

Furthermore, the LEA encourages reuse and consolidation of application system architecture for enterprise application integration with service oriented loose coupling and appropriate built-in security, iteratively through the various layers of architectures (business,data,application) and thereby obliterating existence of the stove pipes systems.

Pragmatically speaking, if applied appropriately, the LEA model can bring in application of technology as an investment and value addition to a business.
