Tom Grave have also published the every day Enterprise-Architecture . Thanks for his generasity , at present you can still download the complete PDF e-book via this link.

In Anything Enterprise Architecture, Tom Grave reply to the discussion on Gartner's new approach for EA. He said:

Several people above have remarked on the usefulness of the Cynefin framework. I strongly agree, and have used similar ideas in enterprise-architecture and strategic assessment for many years - see, for example, my book Everyday Enterprise Architecture: sensemaking, strategy, structures.... Do be warned, though, that Dave Snowden, the current custodian of Cynefin, has very strong views on how Cynefin should and should not be interpreted, and will likely disagree in no uncertain terms to many typical usages of the Cynefin frame in EA. It's probably safest to refer to that mapping of Simple [aka Known], Complicated [aka Knowable], Complex and Chaotic, and the contrast of order and unorder, as a 'Cynefin categorisation' or a 'Cynefin-like frame', rather than 'as' Cynefin itself.

(More detail here, if anyone's interested.)

John Wu and others also referred to Wu Xing (Five Elements), a traditional Chinese framework that's even more layered and meaning-rich than Cynefin. Interestingly, it also aligns well with Bruce Tuckman's 'Group Dynamics' project-lifecycle of forming, storming, norming, performing and adjourning. There's more detail on that, and its application in EA and EA-related work, in the 'Five Elements' chapters in my book SEMPER & SCORE: enhancing enterprise effectiveness. There are also strong cross-links between the Five Elements and key themes in organisational effectiveness (efficient, reliable, elegant, appropriate, integrated): as documented in another of my books, Real Enterprise Architecture: beyond IT to the whole enterprise, this provides a very useful framework for architectural assessment and review at a whole-of-enterprise scope.

If we start from there, Gartner's 'new approach' then provides a very useful checklist and cross-reference to guide a true enterprise-scope architecture.

Hope this helps, anyway.]]> General index.php?itemid=716 Thu, 29 Jul 2010 05:49:02 -0600 index.php?itemid=715 The Business Canvas

Enterprise Topology approach is comparable to the Business Canvas approach. Both Enterprise topology and Business Canvas suggest to know the enterprise via total participation, collabortion and reconciliation. And both suggest to faciliate and articulate the participation, collaboration via tangile artifact of hard copy drawing which works well with a group of poeple. Tom Grave the author of many EA books have a intensive development in the month of July, 2010. This all fresh from the oven. First is The Enterprise Canvas based on Alex Osterwalder’s Business Model Canvas and He further elaborate the enterprise canvas to Contect-space mapping with Enterprise Canvas. Now the Enterprise Topology, the business Canvas, the Enterprise Canvas are all on the same boat.

The differnence between Business Canvas and Enterprise topology is that :

. Business Canvan focus to serve business community; Enterprise topology is intended to serve both business and engineering community.

. The other differeence is that Businss Canvas is a thinking tool to faciliate business modeling. Enterprise topology is a visulization effort with explicit model for tangible utilization.

The bottom line of LEA Enterprise topology approach is a tangible EA product for both business and engineering community to comprehend rather a framework as a EA thinking tool and check list.
Although the enterprise topology appraoch was initiated and used before 2000. It has not been shared with EA community as the business canvas approach do. Enteprise Topology method can learn from the Business Canvas experience to share the method with EA community.

Alex Osterwalder suggest the business canvas approach. It propose a single reference model based on the similarities of a wide range of business model conceptualizations.



The Business canvas has been presented in :

. Business model Canvas Book Business Model Generation,

. Business model Canvas Training Bhsiness model canvas game.

. Business model canvas tools The are several business model cavas tool. Here is one from bm designer.

Egham, UK, August 11, 2009 — Enterprise architects must adopt a new style of enterprise architecture (EA) to respond to the growing variety and complexity in markets, economies, nations, networks and companies, according to Gartner, Inc. Analysts advised companies to adopt ‘emergent architecture’, also known as middle-out EA and light EA, and set out definitions of the new approach.

Despite there are plenty of different comments on this EA approach as list in the following, I do appreciate the value of this approach and feels that LEA and Architecting for Emergnece are convering to a future EA direction.

"For several decades we've heard that effective enterprise architecture programs are a critical success factor for medium-to-large size IT organizations. I have been a promoter of enterprise architecture, both in my writings and working with organizations around the world, yet after all these years it seems that the reality of enterprise architecture is nowhere close to fulfilling some of the rhetoric around it. So I decided to find out what's actually working in practice, and what's not working for that matter, in my Enterprise Architecture Survey Results from the January 2010 DDJ State of the IT Union Survey"

In 2008, Ian Rowland says in Why Isn’t Enterprise Architecture In The Big Time?

"Let’s confess, then, what we really know in our heart of hearts … Enterprise Architecture is a discipline that hasn’t really made it to the big time. If that’s the case, what are the causes? Is EA a rocket that hasn’t got off the launch pad, or a firework that has fizzled? "

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.

John has initiated the e-cio organization. He suggest, in the notion of " eat your own dog food", the office of Chief Information Officer (OCIO) must demonstrate their transition from stove pipe solution to EA culture. It is difficult to convince and get buy-in from the stakeholders when the OCIO has yet making the transition.

John is also a contributing author of the Cutter Consortium and has actively contribute EA thought to the ITtoolbox blog . John has been active to support of the Association of Enterprise Architects DC chapter which provide regularly present EA seminars in Washington DC area.

A topology (from Greek topos meaning place) is a description of any kind of locality in terms of its layout. It is:

A mathematical branch that deal with position. Topology is contrary to common geometry, which puts emphasis on how points, lines and planes are composed in order to create ideal solid forms. Topology does not deal with single object and it visual attributes, but pays attention to how an object may be connected to or situated in relation to another object. []

EA is the study of the relation between technologies and businesses rather than developing a large scale application system.

Under the understanding of EA as the topology rather than a geometry, the study of topology relies the set theory. The Light EA suggests to study the intersections set rather than the union set. It is an effort to establish the common foundation and building blocks to enable the agility and simplicity on taking advantage of technology evolution.

Topography (Greek topos, "place", and graphia, "writing") is the study to render topology in schematic presentation. EA topography is the effort to render a comprehensive EA topology between business, application, data and technology. For more information please read:

EA is not only all about technology. In the early stage of information age, many automation efforts are technology driven because the way that technology has change how business doing business. However, gradually, the community realizes that the evolution of information age got carried away in the technology driven approach to departure from what business need. Under this concern, EA was initiated to align technology and business and resolve the challenge of stovepipe systems. Even so, the technical world still interprets EA as the enterprise scalable system which is technology oriented.

EA is not all about business either. In the last few years, the EA community have swing the definition of EA to the other extreme to suggest the EA is all about business by interpret EA as "Architecting the enterprise" and it is all about business. The notion of EA is all about business has totally missed the point of what EA was initiated. It interprets EA by the word of "Enterprise Architecture" rather than by the origin of EA in the information age. It is unfortunate that it only scratch the surface of the words rather go to the depth of the root. EA is not in cosmetic business. Under this on going movement, EA has become the new name for old paradigm of business transformation which can be accounted from the old days bloody revolution, industry engineering, information engineering, enterprise engineer , business process reengineering and continuous improvement.

Enterprise Architecture is an emerging paradigm rather than enterprise large scale system architecture or the new episode of business improvement and transformation effort. EA aligns technology with business need, see the enterprise big picture to know the enterprise environment, learn experience of the others and establish common foundation and building blocks to enable agile and simple business transformation. Enterprise Architects is an emerging discipline o map technology with business need, the enterprise architect have to know the technology side and the business side enough to establish the relationship.

Having read about the LEA concept, albeit in pieces, the concept seems to be interesting. Lot of thoughts and efforts must have been gone into suggesting an approach that advocates the agility in the enterprise architecture. Thrust on business alignment and mapping technology solutions with the business processes, which most other models of EAs also suggest, is apt. May be a bit of refinement and openness in integrating the enterprise solutions in some form ,albeit in the background, into the EA domain will make it more interesting and comprehensible. Also, one to one comparison with other EA models will strengthen and not weaken the innovative idea of having a light weight EA model. Just some thoughts.

Wishing all the best to John Wu for working on innovative ideas on EA, which at onset look adventurous but may emerge pragmatic with a bit of more refinement and openness.

regards,
