Module 1: INTRODUCTION TO SYSTEMS INTEGRATION AND ENTERPRISE ARCHITECTURE

Three Broad Organizational Aspects:

People, Processes, Technology

Setting up new IT systems and
required infrastructure. Providing technical and help desk support to users.

Technology

Introducing new improved
business processes enabled
by system. Decision making procedures and rules.

Processes

Trainings and Education to
system users

People

Information systems can help organization executes their
business strategies and gain competitive advantage in
terms:

- Operational Excellence and Cost Leadership
- Product differentiation and leadership
- Customer Intimacy and focus

It is closely related to enterprise integration which is concerned with facilitating
information, control, and material flows across organizational boundaries by connecting all the necessary functions and heterogeneous functional entities (information systems, devices application, and people).

System Integration

It was one of the first architectural concepts to bring together the various heterogeneous applications and information systems of an enterprise.

Enterprise Application Integration (EIA)

Four Stages of System Integration

1. Interconnectivity
2. Functional Interoperability
3. Semantic Interoperability
4. Optimization and Innovation for Systems Integration

It is the practice of analyzing, designing, planning
and implementing enterprise analysis to successfully execute on business strategies. EA helps businesses structure IT projects and policies to achieve desired business results and to stay on top of industry trends and disruptions using architecture principles and practices, a process also known as enterprise architectural planning (EAP).

Enterprise Architecture

In what year the Enterprise Architecture was born from "various architectural manuscripts on Business Systems Planning (BSP) by Prof. Dewey Walker"?

1960

He was one of Walker's students who helped formulate those documents into the more structured format of EA.

John Zachman

In what year Zachman published the framework in the IBM Systems Journal?

1987

The EA framework came as a response to the increase of business technology, when computer systems were just taking hold in the workplace.

1980s

Four Leading Enterprise Architect Planning (EAP) Methodologies

-The Open Group Architectural Framework (TOGAF).
-The Zachman Framework for Enterprise Architecture.
-Federal Enterprise Architecture Framework (FEAF).
-Gartner

__________ provides principles for designing,
planning, implementing and governing
enterprise IT architecture. This framework helps businesses create a standardized approach to EA with a common vocabulary, recommended standards,
compliance methods, suggested tools and software and a method to define best practices.

The Open Group Architectural Framework (TOGAF)

This framework is named after one of
the original founders of enterprise architecture
and it's another popular EA methodology. It's better understood as a "taxonomy", according to CompTIA, and it spans six architectural focal points and six primary
stakeholders to help standardize and define the IT architecture components and outputs.

The Zachman Framework for Enterprise Architecture

__________ was introduced in 1996 as a response to
the Clinger-Cohen act, which introduced
mandates for IT effectiveness in federal
agencies. It's designed for the U.S. government, but it
can also be applied to private companies that want to use the framework.

Federal Enterprise Architecture Framework (FEAF)

After acquiring The Meta Group in 2005,
___________ established best practices for EAP and
adapted them into the company's general
consulting practices. While it's not an individual framework, CompTIA recognizes it as a "practical"
methodology that focuses on business outcomes with "few explicit steps or components."
