scope, complication, and risk.
A business organization.
Industrious, systematic activity, especially

is basic to capitalism.
Willingness to undertake new ventures;
Perspective

Enterprise Systems are ones that have a large
scope


involve or integrate all parts of an organization.
Remember that we’ve already studied
Enterprise Collaboration Systems



For an ECS, like Outlook, both the grunts and the
President use it...
Its not specific to the functional areas.
Its not specific to the operations level, tactical level, or
strategic level
Perspective


In the software world, Enterprise is a
buzz word, which usually implies that the
system is very expensive, but can do a lot
In the e-commerce era, an Enterprise is
often more than one company and the
boundaries are unclear...virtual
companies, etc.

Sometimes Enterprise implies that more than
one company is involved.
Supply Chain – Value Chain



2.
Enterprise Systems come from a need to
streamline the value chain in a company.
Functional areas, from Manufacturing to
Marketing, need to be connected.
Multiple functional business systems are being
replaced by one Enterprise Systems
Or, Enterprise System are built on top of
several functional systems.

EAI: Enterprise Application
Integration



How does a business interconnect its
information systems.
Connects Front Office Systems with Back
Office Systems
Example: When an order is complete,
have the order application tell the
accounting system to send a bill and alert
shipping to send out the product.
EAI: Enterprise Application
Integration




EAI provides middleware (Middle Software) that
performs Data conversion between different
systems
coordinates Communication and Message
passing between systems
The idea is to use the existing systems, but to
have a super-system for connecting related
systems.
Summary

There are six types of information systems





6 categories: ECS, TSP, PCS, MIS, DSS, EIS
There are 5 functional areas of business
Some system are designed for a specific
functional area: Accounting
An ECS can touch all the functional
business areas
A TPS might touch 3-4 areas
Summary



ECS and TPS are cross-functional.
Some large functional systems, picture a
huge accounting system, can fit into more
than 1 category, i.e., both an MIS and TPS.
Enterprise Systems by their nature are both
cross-functional and fit into several
categories.
