Enterprise Architecture Matters

Why do we need architecture?

A question still often asked today, is why do we need enterprise architecture. It is intriguing though that, more often than not. the architects are asking the question.

But first, let me ask and answer a few related questions:

Why do we need anatomy to describe the human body?  Why do we need the schematics of a car?

To understand and mend it properly.


Why do we need the architecture (map) of a city? 

To travel around, find points of administration, business and interest.

Why do the builders need the map of the city? 

To find out where the existing city facilities, utilities and transports are to be able to construct the building on a proper site and interconnect it to the usual utilities and roads. 

To change, add and update the many underground systems of cables, pipes... while avoiding break the existing ones, eventually from another utility provider.

...

The architecture is the structure and description of a system/enterprise.

It enables the implementation, understanding, maintenance, repair and further development of a system/enterprise. 

The architect describes a system (enterprise) in an architecture in order to enable its usage, fixing, building and further development.

The architect specifies the architecture,  which essentially consists of a set of integrated blueprints,  starting from requirements and past cases.

The designers/engineers though, take over the blueprint from the architect to further design (the parts of) the architecture to the detail necessary for implementation, proper usage, maintenance and further development.

The architecture describes primarily the current system/enterprise.

It may also describe the target system/enterprise in order to visualise its end state.

The architecture is employed in the process of enterprise transformation to ensure that projects are aligned in an enterprise wide portfolio covering all enterprise entities, the business and technology issues and their dependencies.
