Is the architect’s role to model the

organisation or transform it? • Architecture rooted in a philosophy.

• Expression of the Enterprise’s interaction with its

environment.

• Should express the aspirations of the Enterprise.

Technology driven.

Solution focussed.

Language is often difficult for the

“customer” to understand.

Fails to express a vision for the

business and then link that vision to

the development of capability.

Architectures dominated by systems of analysis

and population of models. Town planner paradigm of pipes and

connections dominates.

Architecture then, in its widest sense as the building art, differs from

other arts, in being not merely essential to man for the full scope of

his highest faculties, but required for his physical comfort, almost for

his very existence. …..which at once requires the least technical

knowledge for its general appreciation, and opens the widest field

for minute inquiries and philosophical speculation. The art… which

presses the noblest of other arts into its service and bends them to

its will .. the most lowly in its origin, the most glorious in its

perfection; slowly and gradually has it risen, and by a more soaring

flight has attained to the unearthly majesty of the Christian

Minster,…

Engineering ready design

The art of the built environment architect is

to capture the aspirations of a client or

community and to express those

aspirations in a design which is

“engineering ready”.

In order for EA to be of true value it must

be expressed in the terms of the

ASPIRATIONS of the organisation. It must

reflect the needs and wishes of the

organisation INTO THE FUTURE

In order to express these aspirations the

EA discipline needs to move beyond the

commonly applied mindset.

Environment is

source of stressors.

Organisational behaviour

seeks to shape

outcomes in the

environment

Information is the means

of skill transfer and

transformation mechanism

: a project or undertaking that is

especially difficult, complicated, or risky

: readiness to engage in daring or

difficult action

: a unit of economic organization or

activity

: a systematic purposeful activity

From our earliest days, the human journey

is typified be people applying process to

the use of technology to shape or respond

to the environment.

EA is an evolutionary process.

It is an architectural process which expresses

the aspirations of a human collective in terms of

people, process, and technology, shaping

and/or responding to the environment.

EA develops an “Engineering Ready” business

aspiration.

EE is about capturing the AsIs and defining the

solutions to deliver the architectural aspiration.
