1	What is Coherent EA ?
2	The Coherent EA CEA define a coherent EA direction. The Coherent EA is the logical course of information age evolution. CEA is a change oriented EA approach. CEA is pragmatic.
3	Define a coherent EA direction CEA is the effort to establish a coherent EA direction with consideration of many existing EA approach. For practical purpose, EA approach has evolved from designing the target architecture blueprint to segment architecture approach. However, there is significant confusion on what is reference model, reference architecture and segment architecture within the EA community. It is essential to define a coherent EA direction for information age to evolve from stove pipe culture to interoperable environment.
4	Part of information age evolution CEA is in the logical course of information age evolution. Information age is evolving from stovepipe culture to interoperable culture similar to the life cycle of industry age. EA was introduced to make transition from a stovepipe culture to a interoperable culture. In the interoperable culture of the information age, it become simple, agile and cost effective to take advantage of automation solution.
5	CEA is a change oriented EA Traditional EA was evolved from application development which is based on a set of static requirements as if it is a jumbo jet project. The static EA do not serve well to an Enterprise which change constantly. CEA is initiated from the aspect of changing world. It address change with segment architecture to close business performance gaps and agility architecture to deliver result to the right people in the right area at the right time.
6	Enterprise is organic Enterprise is organic, in the constantly changing world, an enterprise also changing. The traditional EA which consider EA as the blueprint of jumbo jet do not serve well for a constantly changing enterprise. The book of change which is 5000 year old Chinese wisdom recognize the world is organic establish a model of change similar to a ecosystem. In 1993, The business ecosystem by James Moore says “An economic community supported by a foundation of interacting organizations and individuals--the organisms of the business world. The prosperity of the ecosystem is achieved via maintaining the equilibrium during the constantly changing world.
7	The challenge is the constant Change Constant change is the major challenge of enterprise. CEA enable simple and agile response to manage change. Attempt to predict pattern of change has been part of civilization. for example the “Book of Change” was written 5000 year ago in China. Modern Science has developed computation of pattern probabilities in random sequences und Markov chain models The book of change is based on the similar concept.
8	The CEA goal The CEA short term goal : A pragmatic EA approach to provide architecture solution for business in time of need. The long term goal is: Transform business community into information age. Connect the power of business and engineering for business prosperity. Support decision making to maintain equilibrium in the business ecosystem.
9	Connect Business and Engineering CEA earn Buy-in from business community via: Integrating the power of the right brain business managers and the left brain engineers. One (the right brain) is visual and processes information in an intuitive and simultaneous way, looking first at the whole picture then the details. The other (the left brain) is verbal and processes information in an analytical and sequential way, looking first at the pieces then putting them together to get the whole.
10	Support decision making CEA provide the holistic enterprise environment to support decision making. Business community have used influence diagram to analyze the business impact analysis. Influence diagram can be a complicate hair ball. CEA suggest to leverage on the ancient Chinese wisdom of Yin-Yang Wu-Xing (The Five stage of change) to simplify the impact analysis model.
11	The CEA strategy The CEA strategy include : To comprehend the Enterprise which is logical and invisible. Recognize Enterprise is organic, the world change constantly. Bridge between business and engineering community. Apply Architecture principle as “the orderly arrangement of parts” to: The Business Architecture The Alignment Architecture The Agility Architecture The Management Architecture
12	The structure of CEA
13	CEA Model and Framework CEA address business performance gaps due to the constant change with segment architecture via business and engineering agility and align to the enterprise master plan as shown in the CEA model.
14	See the invisible Enterprise Knowing in part may make a fine tale, but wisdom comes from seeing the whole. See the whole enable critical thinking. The enterprise big picture is logical, none of us can see it. In a sense, we are not different from the blind man. CEA take the blind man and elephant approach to see the logical enterprise big picture. CEA render the big picture in the intuitive Enterprise Map approach.
15	The Enterprise Map CEA suggest the Enterprise map approach as the ice breaker between Business and Engineering. The Enterprise Map see the big picture . answer the frequent question about the organization on the mission, business function, location, organization, automation systems and information associated to business.
16	Business Architecture know the enterprise definition is a major EA value. CEA Define the enterprise from the attribute of mission, function information, organization, location and performance need . The Business architecture also analyze the relation and structure of the enterprise attributes to enable impact analysis.
17	The Alignment Architecture Alignment Architecture align automation solution to business architecture. The Alignment Architecture consist of the following layers: Processes Application Data Security Technology The Notional The Segment
18	Notional Target Architecture Traditional EA has dedicate significant effort to design the Enterprise Target Architecture as the Enterprise Blueprint similar to a jumbo jet project. CEA suggest that the Enterprise Target architecture is the notional from the very high level as the master plan. The Notional Target Architecture establish the fundamental foundation of the Enterprise. The Fundamental foundation by definition do not change frequently. For example: Pierre-Charles L'Enfant's 1791 plan for the city of Washington is one of the great landmarks in city planning.
19	Segment Architecture Segment Architecture elaborate the architecture for a section in the Notional Target Architecture to close business performance gaps. Segment Architecture is the pragmatic EA to deliver EA result to the right person in the right area at the right time. Segment Architecture is the continuous improvement for an Enterprise. A segment architecture is analogy to a segment in a city. A segment architecture is based on business need rather than based on the same engineering category.
20	The Agility Architecture Practical EA approach has evolved to enable agility and simplicity to deliver automation services in time of need to manage the continuous change. CEA has explicitly identify the agility architecture paradigm to incorporate in the CEA model. Reference model Reference Architecture Standards Governance Reuse Consolidation
21	Management Architecture The management architecture include Performance management. Change management. Investment management Project Management Configuration management Service management
22	The CEA Approach Develop the notional Enterprise Target Architecture Enable agility and simplicity via learning experiences from the same line of business. Business performance gap analysis is a continuous effort. Segment architecture to elaborate the notional target architecture and close business performance gaps.
23	CEA level of effort The chart shows the level of effort in CEA: Segment Architecture is the major effort. Agility Architecture comes next. The others share equal parts on the level of effort. CEA deliver value from the beginning to see the holistic enterprise for critical thinking.
24	The real life example of CEA City planning is the real life example of CEA. It obtain the city big picture via engineering survey. Conduct the city master via high level and notional city plan. Develop and improve the city based on the business need and population growth. The city infrastructure enable agile business and residential development. The city management enable the prosperity of the city.
