Light EA suggest that Enterprise Architecture is a Holistic + Scientific method to support complex system. “Enterprise” means the whole in the holistic philosophy. “Architecture” by definition is the orderly arrangement of the parts. It is an atomistic in the scientific paradigm.
This web site discuss EA from the aspect of the evolution of EA and suggest that EA after all is a holistic + Scientific architecture approach method to support complex system . It is an approach for the practitioners to see the whole and know the parts. EA is not a frozen enterprise wide architecture blueprint. The web site elaborate that the Holistic + Scientific architecture approach enable IT community to support Adoptive IT architecture; Business community integrate the left/right brain; cultivate enterprise collaborative culture to win the edge of competition. Please use the top menu to drill down to learn more abut the Holistic + Scientific approach. This web does not explain “What” the Holistic + Scientific method but also shows “How” if you wish.
The following list summarize the innovative EA ideals.
- A Tangible EA approach
- EA is a matter between Scientific and holistic paradigm.
- Enterprise map enable every one in the enterprise to see the whole.
- EA to design not only the enterprise mechanism architecture but also the enterprise influence architecture.
- EA is a complex adaptive architecture method base on vertical, horizontal and circular architecture theory in a three tier approach.
Please use the top menu bar for more detail on each area.
1. THE TANGIBLE EA
A tangible EA on Architecture Drawings
Light Enterprise Architecture was initiated as a light and tangible EA method by practicing EA like a traditional architect. Under the rapid technology evolution days. It seems an out of date and obsolete approach in the effort of paperless world. However, human cognitive capability has not evolved biologically in the last couple thousand years and human have the same cognitive capability. Traditional architects have established Architecture drawings and size as the best practice to communicate with customers. To address the concern of “Stealth EA”, although the Enterprise Architects have done a lot work in modeling, analysis, but most of the hard work are buried in the EA repository and volumes of documentation for no one to comprehend. LEA adapt the traditional Architecture Drawing approach to communicate with both business and technical community as shown in the following figure.
By saying Light Enterprise Architecture does not means EA is simple, it is an continuous effort and the architecture drawings is only the tip of the EA iceberg for EA to be visible. Under the visible architecture drawings, there is a very large invisible body of enterprise because Enterprise is organic. The flowing LEA capability map further elaborate LEA.
2. EA IS A MATTER BETWEEN SCIENTIFIC AND HOLISTIC PARADIGM
EA is a matter between scientific and holistic paradigm rather than a matter between IT or Business. EA community like to debate about ” EA is about business or technology?” Because the term of “Enterprise Architecture” is very miss leading . From the title, EA seems about Business based on the common definition of “Enterprise” in dictionary. However, From the origin, Enterprise Architecture was initiated to overcome the challenge of redundant IT efforts in the information age. It is not all about business. Instead of consuming the energy to debate about EA is IT or business, it will be more constructive to consider EA is matter between scientific and holistic paradigm. In the modern age, the scientific trained community like to to draw a line between scientific and holistic paradigm and look down holistic approach as non-scientific. However, it is not necessary to draw a line in the sand between scientific and holistic approach, EA is a matter between scientific and holistic paradigm to wash away the line between scientific and holistic.
Enterprise Architecture = Holistic + Scientific = See the whole + know the parts
3. ENTERPRISE MAP ENABLE EVERY ONE TO SEE THE WHOLE
The challenge to “see the whole” because most of people only knows the parts they have touched and “See the Whole” is a privilege of some wise men. People also like to consider the part they have touch is the whole.
. Enterprise map serve the following purpose.
- Enable every one to see the enterprise
- Document the enterprise environment
- Plan for the future
- Align business organization, business location and technology to business need.
- Enable sharing and reuse to minimize Redundant investment.
- Enable enterprise agility in adopting to change.
The Enterprise map is composed based on the following architecture framework. the enterprise map document the as-is enterprise environment from the aspect of why, what, how, who, where and when also serve well to examine on how well the business organization and location support business capability based on stakeholders need. For example to examine the proper alignment of business capability and application systems. Frequently, enterprise architect use enterprise map to discover redundant application system investment or identify areas to take advantage of technologies. Enterprise map does not only enable every one to see the enterprise big picture, it is also a very powerful analysis tool to document the As-is environment and planning for the target environment.
4. EA TO ARCHITECT NOT ONLY THE MECHANISM RELATION BUT ALSO INFLUENCE RELATION
EA does not design the mechanical structure but also the influence structure as shown in the following framework. The framework serve both the EA community and the business community. EA community like to focus on enterprise mechanical structure, However Business community are much more interested on the enterprise influence relation to make strategic decision. The Zachman framework is the thinking tool to architect the enterprise mechanical architecture in vertical and horizontal direction. The Coherence model is the thinking tool to architecture the enterprise influence architecture in circular direction.
5. EA IS AN ADAPTIVE ARCHITECTURE METHOD TO SUPPORT ORGANIC ENTERPRISE
The adaptive IT architecture consist of the Vertical Architecture to align technologies with business; Horizontal Architecture for sharing, reuse and enable enterprise agility in adopting to change; the Coherent Architecture to support complex adaptive system in a holistic and coherent approach. Instead of a big bang approach, The adaptive IT architecture approach is a three tier approach. EA do not have to be difficult, In the beginning, it is only a high level planing effort similar to city planning as shown in the initial EA; However, EA is continuous effort to close the gaps of business performance gaps due to constant change in the organic enterprise as shown in the continuous EA section; Further more, Enterprise Architects are the “Glue” not the “Guru”, they interact with managers, planner, engineering and contractor daily to enable enable enterprise agility and simplicity in taking advantage of technology evolution.
EA is not all about Information Technology architecture
Enterprise Architecture is not all about architecture, it preserve the institutional knowledge and facilitate enterprise collaborative culture with total participation. The LEA framework discuss EA based on the attributes of why, what, how, who, where and when in the row of
- See the whole
- Enterprise Fields Architecture of knowledge, communication, security, governance and collaboration.
- Enterprise Business Architecture to integrate the power of left/right to win the edge of competition.
- Enterprise IT Architecture in adopting to change.
THE LEA Concept
The capability map describe that LEA enables every one in the organization to see the whole and know the parts; Recognize that Communication, Collaboration, Governance and Security as the fields of an Enterprise; Analyze enterprise business architecture; Adapting to change with the the adaptive IT architecture approach based on three architecture theories in a three tiers of architecture practice; LEA bridge the gaps between strategy and execution via the bound of enterprise fields. Most Business failure frequently not because of lack of sound strategy but due to poor execution. Enterprise architecture is also the foundation of execution.
The LEA Poster
The LEA poster summarized all the holistic architecture analysis for all the LEA capabilities as shown in the following figure.
Please view the LEA poster in the PDF form.
Idealistically, EA is most valuable to facilitate the collaborative culture rather just of the Enterprise IT and Business. However, in reality, it is more practical for an organization to engage EA from the aspect of Information Technology and extend EA to business.
- What is EA? discuss the EA definition, EA backgroud and EA discipline.
- Paradigm shift from mechanical architecture paradigm to Holistic + Atomistic architecture paradigm. EA is not an enterprise wide solution architecture.
- Establish EA culture in an organization It is futile to architect the enterprise without buy-in from the stakeholders. The first thing of EA is to establish the collaborative EA culture. please read the EA Culture to establish Enterprise Collaborative Culture based on Enterprise Field theory rather in a mechanical approach.
- For IT community please read the EA on IT , which is an adaptive IT architecture,
- For Business community please read EA on Business which integrate the power of left/right brain to win the edge of competition.
