Among many different EA frameworks of
nowadays, there are four of them which have the most popularity: Zachman
Framework, TOGAF, FEA, and Gartner.
The Zachman Framework, which consists of
two dimensional classification matrix based on six basic questions (Why, How,
What, Who, Where and When), provides a formal and highly structured way of
viewing and defining an enterprise. It is much more like a methodology that
leads architect designer to think about enterprise architecture.
The
Open Group Architecture Framework (TOGAF) is a
framework, which provides a comprehensive approach for designing, planning,
implementing, and governing an enterprise information architecture. Nowadays,
The Open Group has grown to be a global consortium that enables the achievement
of business goals by designing IT standards.
The Federal
Enterprise Architecture could provide a common
methodology for information technology acquisition, use and disposal in the
Federal government. It provides several models for reference, such as PRM, BRM,
SRM, DRM and TRM. Since the U.S Government may be the most complex organization
in the world, the FEA could also be applied into many other cases for its
advantages in many areas.
Gartner
Gartner is one of the most famous IT research and consulting organizations
in the world. It believes that if the architect designer brings together three
constituents together, which are business owners, information specialists, and
the technology implementers and unify them behind a common vision that drives
business value, the EA would success.
Considering the demand of companies and advantages
of EA frameworks, we could find that those frameworks have been widely applied
in designing enterprise architecture and grow with the development of
complexity in enterprises’ business. Take MedAMore as an example, with MAM’s
business expansion, it purchased three regional chains and came across IT
problems. These IT problems could be classified into two categories:
1.
The requirement of changing some
modules in the system due to the development of business.
2.
The delay of file transfer
because of the regional difference.
The company realized the difficulties in
dealing with those problems and sought for solution by applying EA framework. Supposed
that these problems are solved by using EA framework, the return of investment
would reflect in following areas:
1.
With more regional chains, IT
would keep supporting business development.
2.
The reduction of payments in
operating the company.
3.
The increase efficiency in
running IT system and business process.
