EA topology is the effort to document
institutional knowledge. |
|
Institutional knowledge is abstractive and
buried deeply in each individual. |
|
EA topology must be established with systematic
approach. |
|
Every thinks they know the big picture. |
|
No one really can see the big picture by
themselves. |
|
|
|
|
|
|
|
|
|
|
Putting together the topology is similar to the
challenge of a complicate jigsaw
puzzle without a picture on the cover and without the pieces. |
|
The effort is to trawl the pieces of
institutional knowledge deeply in individual mind. |
|
Put the pieces together with ratification from
the stakeholders to see the big picture. |

|
The folk story of stone soup. |
|
It is more than trawling the information |
|
The model of stone soup |
|
Intrigue the curiosity - by setting up a pot
with water and the magic stone. |
|
Articulate the participation - by saying it will
nice to have more ingredient. |
|
Partnership – Every one enjoy the soup. |
|

The
three iteration |
|
Intrigue the curiosity |
|
Articulate the collaboration |
|
Partnership |
|
|
|
|
|
|
The architect articulate the collaboration by |
|
Interview and apprentice |
|
Workshop – To get the institutional knowledge
with intensive workshop by facilitating. |
|
Wall paper – To get the institutional knowledge
on the paste of stakeholder rather than pushed by the time window. |
|
Jigsaw puzzle technique suggest than brain work
overnight to get clear picture. |
|
|
|
|
|
|
The last iteration does not only ratify the EA
topology but also create partnership. |
|
The stakeholder take the ownership and become
the proponent of EA to work toward architecture buy-in. |
|
The outcome of the the EA topology is very
different from what each individual observation. |
|
Each stakeholder benefit from seeing the big
picture and anxious to share with the others of what they have contributed. |
|
Architecture buy-in start at the very beginning
of EA rather at the end of architecture design. |
|
|
|
|
|
The EA topology is established in seven layers
as shown on the figure: |
|
The framework based on line of business. |
|
The workplace and geographical distribution. |
|
The business function by workplace. |
|
The high level business process flow. |
|
The application systems and technology associate with functions. |
|
The data sources and technology supporting the applications. |
|
The index of the topology. |
