Summary
In 1987, John Zachman, wrote: "To keep the business from disintegrating,
the concept of an information systems architecture is becoming less of an
option and more of a necessity." From that moment on, the Enterprise Architecture
Framework of Zachman evolved. It became the model around which many major
organizations are viewing and communicating their enterprise information infrastructure.
It provides a blueprint, or architecture, for the organization's current and
future information infrastructure.
The Zachman Enterprise Architecture at that time presented a new model
for viewing and communicating information infrastructures.
Instead of looking at the process as a series of steps, he organized
it around the points of view (perspectives) taken by the various players.
Players in the Enterprise Architecture framework
Someone who has undertaken to do business in a particular industry.
Business people who run the organization.
Systems analyst who wants to represent the business in a disciplined
form.
Designer, who applies specific technologies to solve the problems of
the business.
Builder of the system.
System itself.
The perspectives or points of view are represented as rows
in the matrix (see figure below).
Zachman acknowledged that each of the participants was looking at the same
categories of information, represented in the columns in the
framework.
Information Categories in the Enterprise Architecture framework
The data manipulated by an organization (what).
Its functions and processes (how).
Locations where business is conducted (where).
Events that trigger business activities (when).
People and organizations involved (who).
Motivations and constraints which determine how the business behaves
(why).
An "Enterprise" is a business association consisting of
a recognized set of interacting business functions. It is capable to operate
as an independent, standalone entity. With this definition, there can be
enterprises within enterprises. For instance, a business unit within the
overall corporate entity may be considered an enterprise as long as it could
be operated independently. The enterprise can also be seen as an "Extended
Enterprise", meaning that the scope of the impact of an enterprise architecture
effort could also include inter-relationships with external entities. Such
as: suppliers, business partners, and customers.
"Architecture" provides the underlying framework. This
defines and describes the platform required by the enterprise so that it
can attain its objectives and achieve its business vision. It can be defined
as: the set of principles, guidelines, policies, models, standards, and
processes that, aligned with business strategy and information requirements,
that is guiding the selection, creation and implementation of solutions
that are aligned with future business direction.
