EA on Architecture Drawings
Coherent EA approach adopt the traditional architecture/engineering drawing approach to develope, communicate, certify and deliver EA artifacts. The CEA architecture has developed the following Enterprise Architecture drawing sets :. EA Maps : To describe enterprise business in a nutshell.
. Business Architecture drawing set : To analyz the structure of enterprise from the aspect mission, function, information, organization, location and performance requirements.
. Data Architecture drawing set. : To align enterprise information with business architecture and analyze enterprise information structure.
. Application Architecture drawing set. : To align enterprise application serivces with business architecture and analyze the enterprise application service structure.
. The enterprise technology architecture baseline. : To illustrate the enterprise technology architecture baseline for every technology domain defined in the Technical reference model.
Why EA architecture drawing
. EA is known to be stealth due to lack of practical communication mechanism.
. Significant EA work become hidden treasure in the repository.
. Communicate Enterprise Architecture design with architecture drawings instead of volumes of document.
. Architecture drawing has been the proven architecture communication mechanism.
Architecture drawings serve as a communication package
The architecture drawings serves as the EA communication package to contain defined EA artificats.
The Utilization of EA architectrure drawings :
. To know the enterprise via architecture drawings.
. Develope EA via architecrure drawing.
. Communicate EA via architecture drawings.
. Certify EA via architecture drawings.
. Deliver EA via architecrure drawing.
Drawing oriented EA approach
The CEA method adopt the traditional architecture by developing EA from the drawing board in the follow approach:
. Step 1: To see the big picture and know the enterprise via EA Map which analogy to geographical survey. I have developed this method from the swim-lane model for more than ten years. This is version 3, please review the method in the EA Map blog.
. Step 2: To analyze the Enterprise Business Architecture with business architecture drawing room the aspect of Mission (Why), Function (How), Information (What), Organization (Who), Location (Where) and Performance requirement (When). The drawings are backed up with much architecture analysis.
. Step 3. To analyze the application architecture with the application architecture drawing which align application system to support business.
. Step 4. To analyze the data architecture with the data architecture drawings which align data resources to support business.
. Step 5. Establish Enterprise technology architecture baseline with the technology architecture baseline drawings, which illustrate the enterprise technology baseline environment.

Technology Architecture Baseline
One of Enterprise Architecture effort is to document the Enterprise Technology Architecture Baseline standards. It is not only an effort to answer goverment auditing but is also essential for the IT community know the enterprise standard IT environment. Instead of document the Technology Architecture Standards in volumes of documents, CEA suggest to document the technology archtiecture baseline via architecture drawings sets.The Technology Architecture Baseline drawings illustrate the enterprise technology architectuture baseline. The technology architecture drawing set illustrate every technology domain descrirbed in the Technology Reference Model in the following categories. The Technology Architecture Baseline drawing consist of :
The Architecture
The Standards assocaite to the architecture.
