Introducing the Architect’s paradigm into Microsoft

Introduction

Enterprise ArchitectureThe rational design of an Enterprise has been the hope and dream of CEOs, CIOs, Entrepreneurs, and managers since the advent of Frederick Taylor’s introduction of Scientific Management. However, it was not until recently were there sufficient tools to adequately describe and specify the richness that is Enterprise. This presentation will provide just a brief insight to the research being conducted in this area.

Agenda

Architect’s Paradigm examined Enterprise Architecture Microsoft experience Conclusions and Lessons learned Questions

Architect’s Paradigm examined

What is the purpose of Architecture ? What is Architecture ? Architectural Scope Architectural Theory

Architecture is a riddle, wrapped in an engima,

hidden in a mystery...

Architecture’s Purpose

is the management of complexity

This is accomplished through:ReductionOrganization

What is Architecture ?

A set of rules that determine choice, the usage, and organization of elements to create a “Built Environment”

Examples of these elements in Dwelling Architecture are:

Space, Light and Texture

FunctionComponentry

Drawings are not Architecture

Architecture is expressed through architectonics Commonly called design

Drawings represent the intentions ( plans ) of the design process. Commonly called “a design”Blueprints are one form of drawing

Seitz’s Maxium -For differentiating Architecture and Design:

If you can impliment more than one way, you are likely to have an Architecture.

Corollary: If you can impliment in only one way, you have a Design.

Drawings are Design representations

Drawings manage design complexity through reduction.

Built Environments require a family of drawings

What is Enterprise Architecture ?

Describes the structure and dynamics of an Enterprise

Encapsulates the rules of selecting and organizing components into a purposeful whole.

Is multi-dimensional like Dwelling Architecture

The Enterprise Architecture Planning Process

Control and coordination of change, distribution, and integration

Facilitates decision making Managed as a milestone-based process Results are measurable and visible to

the organization Required for successful deployment of

distributed client/server technology

Organizational redesignThe organizational models chosen for

IT Organizations must have give them the ability to :

a) develop leveraged partnerships

with the business units

b) respond rapidly to changes in the business environment

Conclusions and Lessons learned

For both organization and architectural team The simplicity and elegance of architecture can

be deceiving

Communications

Learning is essential

Extremely important Extremely difficult

Rapid shallow cycles are best

Issues on the Horizon

What’s in, what’s out ? What does it mean ? Where can I find… Semantic integration Inventory control

Ontological management and control

PS, If you plan on going Object Oriented your going to need an Ontology management system real bad!
