Enterprise Resource Planning (ERP) is defined by Baltzan as "a single IT system used by businesses in integrating information and functions in different departments so that employees have access to real-time information to accurately make a business decision".
ERP has two key components:
(1) A central database where the information
are gathered and then transmitted to modules is the heart of the ERP. When a user changes any
information in one module the whole ERP system gets updated automatically.
(2) The evolution of ERP started in the early 90’s with its original purpose was for materials planning, has evolved in the 2000’s to include warehousing, distribution, and order entry. In addition to its previous intended uses, ERP system now currently includes project management, knowledge management, workflow management, CRM, human resource management, portal capability and integrated financials which are collectively called ERP II.
Baltzan also emphasized that ERP can be further
divided into core ERP components
which are included in a traditional ERP component and is mainly used in
internal operations and there’s extended
ERP components which are additional components that are not in the
traditional one and mainly used in external operations. The core ERP components include Accounting
and Finance, Production and materials management, and Human Resources. Business Intelligence, Customer Relationship Management, Supply Chain Management and Ebusiness are included in the extended
(A detailed description of the core and extended ERP components can be obtained from Business Driven Information Systems by Baltzan and Phillips.)
