This document provides an overview of enterprise systems and ERP implementation. It discusses the evolution of ERP from materials requirements planning systems in the 1970s to modern extended ERP solutions. The document also outlines some key risks and benefits of ERP implementation, including integration challenges, expense, and improved decision making. Additionally, it briefly describes related technologies like CRM, business intelligence, supply chain management, and data warehousing.

3.  Enterprise resembles a group of people with a
common goal. It has certain resources at its
disposal to achieve the goal.
 Enterprise system (ES) is an ideology of planning
and managing the resources of an entire
organization in an efficient, productive and
profitable manner, and is manifested in the form
of configurable information system packages.

4.  Information system is a set of people,
procedures and resources that collects,
transforms and disseminates information in an
organization.
 “An Information system (IS) can be organized
combination of people, hardware, software,
communication networks; and data resources
that stores and retrieves, transform and
disseminate information in an organization”

8.  Business modeling is the activity of representing
processes of an enterprise, so that the current
process may be analyzed and improved
 Business modeling (creation of business model) is
considered as the first activity in any ERP project
 A business model describes the rationale of how
an organization creates, delivers and captures
value.

9.  Enterprise resource planning systems (ERP)
are management information systems that
integrate and automate many of the business
practices associated with the operations or
production aspects of a company
 These typically include manufacturing,
logistics, Distribution, inventory, shipping,
invoicing and accounting
9

10.  ERP is the technological backbone of e-
business, an enterprise-wide transaction
framework with links into sales order
processing, inventory management and
control, production and distribution planning
and finance.

11.  Before year 1960 : business has to depends
on classical inventory management of
scientific inventory control
 In Year 1960 : The concept of ERP was
limited to the fact that organizations want to
integrate functions and department s to
increase revenue
11

12.  Year 1970: the focus shifted to material
requirement – Material requirements planning
systems developed
 Year 1980: MRP II (materials requirement planning
II) included areas such as project management,
shop floor and distribution management
 Year 1990: Enterprise wide inter functional co-
ordination and integration
 Year 2000: Extended ERP came into market which
offers extended services
12

13.  Business Integration
 Flexibility
 Better analysis and planning
capabilities
 Use of latest technology

Any ERP Architecture has to designed for three
basic functional areas:
1. Database
2. Clients
3. Application components

17.  Risk is a problem that has not yet happened
but which could cause some loss or threaten
the success of project if it did
Types of risks:
1. People risks
2. Process risks
3. Technology risks
17

18.  People – employees, management, implementation
team, consultants and vendors
Risks related to people:
1. Change management
2. Internal staff adequacy
3. Training
4. Employee relocation and re-training
5. Top management support
6. Discipline
7. Resistance to change

24.  The term Business Intelligence (BI)
represents the tools and systems that play a
key role in the strategic planning process of
corporation
 Business intelligence systems gather data
from multiple sources and process by means
of advanced analytics and reporting
supporting decision making
24

25.  “A data warehousing is subject oriented
integrated non-volatile, time varying collection
of data in support of its decision making
process”
Characteristics:
1. Subject oriented
2. Integrity
3. Time variant
4. Non - volatile
25

26.  Data mining or Knowledge Discovery in Database
(KDD), is the nontrivial extraction of implicit,
previously unknown and potentially useful
information from data.
 This encompasses a number of different
technical approaches, such as clustering, data
summarization, learning classification rules,
finding dependency networks, analyzing changes
and detecting anomalies
26

27.  Online analytical processing (OLAP) is a method
of analyzing data in a multi-dimensional format,
often across multiple time periods, with the aim
of uncovering the business information
concealed within the data
 OLAP defined as “The dynamic synthesis,
analysis and consolidation of large volumes of
multidimensional data”
27

28.  Business process re-engineering is a fundamental
rethinking and radical redesign of business
processes to achieve dramatic improvements in
cost, quality, speed and service.
 BRP defined as “ BRP encompasses the
envisioning of new work strategies, the actual
process design activity, and the implementation
of the change in all its complex technological,
human and organizational dimensions.
28

29.  PLM is a strategic business approach that
applies a consistent set of business solutions
in support of the collaborative creation,
management, dissemination and use of
product definition information across the
extended enterprise and spanning from
product concept to end of life

30.  Supply chain management is the systematic,
strategic co-ordination of the traditional
business functions and tactics across these
business functions within a particular
company and across business within the
supply chain, for the purpose of improving
the long-term performance of the individual
companies and the supply chain as whole.
