The EA drawing initiative is an effort to develop Enterprise Architecture
drawing products to communicate EA artifact to IT community. LEA adopts the traditional architecture and engineering drawings
approach to communicate EA knowledge with stakeholders because it have been the most effective tool to convey architecture
information to customers and stakeholders in the past. Traditional
EA approach deliver architecture artifacts in heavy volumes of documents,
large spread sheets and stealth repository.
While the EA professional may enjoy the profoundness and in depth
analysis, the stakeholder and IT community have suffered difficulty to
comprehend the EA artifact which they have invested.
It is necessary to define architecture products to enable
architecture delivery and communication.
The Department of
Defense Architecture Framework has specified the C4ISR
products .
The ideal of large size architecture drawing is to put the EA
artifacts shoulder to shoulder together for easy comprehension. An
architecture drawing can contain large amount of information with graphic
presentation.
Architecture
drawings are developed on Visio using a old HP plotter. Unlike traditional
architecture office, IT
community are not equipped to handle large size
drawings. The original drawings are developed in architecture size
D (36”x24”). After many years of experiment, it is found size C
(24”X 18”) is more practical both in production and portability. The other challenge of large drawings is how to display
the drawings for easy access. To
overcome this challenge the author have created a simple but useful
drawing display system.
The purpose :
The architecture drawing is an effort to support the EA communication.
- Serve
as a container to pack architecture information for pass around.
- Serve
as a EA communication protocol to convey EA information in a
explicit manner.
- Enable
architecture design certification. Enterprise Architects are
reluctant to certify architecture without a clear definition of
liability. Architecture
drawings clearly define the architecture design content and enable the
possibility of architecture design certification from professional
architects.
