Enterprise Resource Planning (ERP) software helps companies coordinate information across business areas like marketing, supply chain management, accounting, and human resources. ERP programs use a shared database and reporting tools to manage business processes from a company-wide perspective. Functional areas within a business, like marketing and accounting, are interdependent and require data sharing to operate efficiently. Business processes integrate functional areas and are collections of activities that create value for internal or external customers. ERP systems improve information sharing between functional areas and business processes.
2. Introduction
• Enterprise Resource Planning (ERP) programs: Core software used by
companies to coordinate information in every area of business
• Help manage companywide business processes
• Use common database and shared management reporting tools

Information Systems
7. Types of System with respect to Size:
Sub System:
A system within a system.
Super System:
When a system is a part of a larger system, the larger
system is called as the Super System.

• Government of Pakistan
2- Sub System:
-- Government of Punjab etc.
Information Systems
9. Types of System with respect to Nature:
• Physical System:
The business firm is a Physical System transforming input (raw
material) into output (finished goods or services).
• Conceptual System:
A system that uses conceptual resources (data & information)
to represent a Physical System.
Information Systems
10. 0- System:
• Business
1- Conceptual System:
• Rules and Regulations
• Standard Operating Procedures ( SOPs )
• Strategies
• Software Systems
2- Physical System:
-- The Whole Organization
Information Systems
11. •Data vs. Information
•Collection of raw facts & figures is called Data
• e.g. Marks of Students in Quiz # 1
•Information is Data shaped into meaningful form
•Processed form of Data is called Information
• Eg List of TOP 5 Students in Quiz # 1
Information Systems
13. •Information system:
• Any organized combination of people, hardware, software, communication
networks, and data resources that collects, transforms, and disseminates
information in an organization
• Information system: Three activities produce information organizations
need
• Input: Captures raw data from organization or external environment
• Processing: Converts raw data into meaningful form
• Output: Transfers processed information to people or activities that use it
• Feedback & Control Mechanism:
• Output returned to appropriate members of organization to help evaluate or
correct input stage
Information Systems
14. An information system contains
information about an organization
and its surrounding environment.
Three basic activities—input,
processing, and output—produce
the information organizations need.
Feedback is output returned to
appropriate people or activities in
the organization to evaluate and
refine the input. Environmental
actors, such as customers,
suppliers, competitors,
stockholders, and regulatory
agencies, interact with the
organization and its information
systems.

15. The Dimensions of High Quality Information
•Complete–should cover all areas of the decision being
made.
•Correct–without any mistake/error - strive for 100%.
•Relevant–must belong to the problem at hand.
•In-Time–should be available for decision making before
a crisis situations develop or opportunities are lost.
Note: Information overload is having too much information.

19. Computer Hardware & Computer Memory
• The term ‘Hardware' refers to the physical components that you can
see and touch, such as the computer hard drive, mouse, and keyboard.
• Computer Memory is any physical device capable of storing
information temporarily like RAM (random access memory)(primary
memory), or permanently, like Hard Disk/USB etc.
• Types of Memory
• Primary memory is the main memory of the computer which can
be directly accessed by the central processing unit.
• Secondary memory refers to the external storage device which can
be used to store data or information permanently.
20.
21. Input Devices
• An input device is a hardware used to send data to a computer.
An input device allows users to communicate and feed instructions
and data to computers for processing, display, storage and/or
transmission.
• Human-captured data refers to input captured by a person typing on
a keyboard, clicking a mouse, speaking into a microphone, or a similar
interaction.
• Machine-captured data is data captured by an electronic device.
• Point-of-sale terminals are scanners used in retail stores.
22. Output Devices
• An output device is any device used to send data from a computer to
another device or user. Examples include monitors, projectors,
speakers, headphones and printers.
23. Computer Software
• The term ‘Software' refers to the set of electronic program
instructions or data a computer processor reads in order to perform a
task or operation.
• Software can be categorized according to what it is designed to
accomplish. There are two main types of software:
systems software and application software.
24. Types of Software
• Systems software (also known as operating system software) includes
the programs that are dedicated to managing the computer itself,
such as Windows, file management utilities, and disk operating
system (or DOS).
• The operating system manages the computer hardware resources in
addition to applications and data.
• Application software, or simply applications enable the user to
complete tasks, such as creating documents, spreadsheets, databases
and publications, doing online research, sending email, designing
graphics, running businesses, and even playing games!
• Application software is specific to the task it is designed for and can
be as simple as a calculator application or as complex as a word
processing application.
25. Home Computing Security
• Viruses are small computer programs that replicate by inserting
themselves into computer resources such as programs or files.
• Antivirus software is a program that is designed to prevent, search
for, detect, and remove software viruses and other malicious and
infected software.
• Norton, MacAfee, Kaspersky etc. Keep virus definitions updated.
26. Networks
• A computer network is a set of computers connected together for
the purpose of sharing resources. The most common resource shared
today is connection to the Internet. Other shared resources can
include a printer or a file server. The Internet itself can be considered
a computer network.
• Network interface card (NIC) is used to attach a device to the
communications medium.
27. Types of Networks
• Local Area Network (LAN) is a computer network that
interconnects computers within a limited area such as a
residence, school, laboratory, university campus or office
building.
• Metropolitan Area Network (MAN) is a computer network
that interconnects computers and usually spans several
buildings in the same city or town.
• Wide Area Networks (WAN) are used to connect computers
and other devices when the distance exceeds the constraints
of LANs and MANs.
• Uses common carrier, public telephone system
• WANs have been replaced by the Internet.
28. Electronic Commerce
• Electronic Commerce (E-commerce) refers to a business transaction that
uses network access, computer-based systems, and a Web browser
interface.
• Business-to-consumer (B2C) refers to transactions between a business and
the final consumer of the product.
• Business-to-business (B2B) refers to transactions between businesses in
which neither one is the final consumer.
• Electronic Government (E-gov) refers to transactions between a
government agency and typically a citizen.
29. Electronic Commerce
• Main benefits to firms:
• Improved customer service before, during, and after the sale
• Improved relationships with suppliers and the financial
community
• Increased economic return on stockholder and owner
investments
• Main constraints to firms:
• High costs
• Security concerns
• Immature or unavailable software
30. The Next Step for E-Commerce
• M-Commerce (Mobile Commerce) is the buying and selling of goods
and services through wireless handheld devices such as smartphones
and tablets.
• As a form of e-commerce, m-commerce enables users to access
online shopping platforms without needing to use a desktop
computer.
31. Virtual Sales
• Virtual sales are those made by a firm that does not operate a physical
storefront.
• Customer can’t enter and purchase the product.
• Virtual Sales Challenges
• Provide necessary product information without overwhelming the customer.
• Communicating image files from the Web site to the customer’s computer can take time.
• Payment over the Internet has suffered bad press–credit card fraud.
32. Hybrid Sales
• Hybrid sales occur when firms have both a physical storefront and a Web site where
customers can purchase products.
• Brick-and-click operations
• Most firms had storefronts before sales over the Internet were possible.
• Both a physical storefront and the Internet are necessary to their business plans.
• Stores act as showcases for products.
• Customers enjoy convenience of shopping over the Web.
• B2C sales means less inventory at its store; more sales floor space.

74. Business Information Value Chain &
Strategic Objectives of ERP
Chapter FIVE
Enterprise Resource Planning
75. •Business perspective on information systems:
• Information system is instrument for creating value
• Investments in information technology will result in
superior returns:
• Productivity increases
• Revenue increases
• Superior long-term strategic positioning
76. •Business information value chain
• Raw data acquired and transformed through stages that
add value to that information
• Value of information system is determined by extent to
which it leads to better decisions, greater efficiency, and
higher profits
78. From a business perspective, information
systems are part of a series of value-
adding activities for acquiring,
transforming, and distributing
information that managers can use to
improve decision making, enhance
organizational performance, and,
ultimately, increase firm profitability.
The Business Information Value Chain
79. •Investing in information technology does not
guarantee good returns
•Considerable variation in the returns firms
receive from systems investments
•Factors:
• Adopting the right business model
• Investing in complementary assets (organizational
and management capital)
80. •Complementary assets:
• Assets required to derive value from a primary
investment
• Firms supporting technology investments with
investment in complementary assets receive
superior returns
• E.g.: invest in technology and the people to make
it work properly
81. • Complementary assets include:
• Organizational investments, e.g.
• Appropriate business model
• Efficient business processes
• Managerial investments, e.g.
• Incentives for management innovation
• Teamwork and collaborative work environments
• Social investments, e.g.
• The Internet and telecommunications infrastructure
• Technology standards
82. In a sociotechnical perspective, the performance of a system is optimized when both the
technology and the organization mutually adjust to one another until a satisfactory fit is obtained.
A Socio-technical Perspective on Information Systems
83. 6 Strategic Business Objectives of ERP
• Business firms invest heavily in information systems to
achieve six strategic business objectives:
1) Operational excellence
2) New products, services, and business models
3) Customer and supplier intimacy
4) Improved decision making
5) Competitive advantage
6) Survival
84. 1) Operational Excellence
• Improvement of efficiency to attain higher
profitability
• Information systems technology serve as an
important tool in achieving greater efficiency
and productivity
85. 2) New products, services, and business
models
• Business model: describes how company
produces, delivers, and sells product or
service to create wealth
• Information systems and technology are
major enabling tools for creation of new
products, services, business models
86. 3) Customer and supplier intimacy
• Serving customers well leads to customers
returning, which raises revenues and profits
• E.g. High-end hotels that use computers to track
customer preferences and use to monitor and
customize environment
• Intimacy with suppliers allows them to provide
vital inputs, which lowers costs
87. 4) Improved decision-making
• Without accurate information:
• Managers must use forecasts, best guesses, luck
• Leads to:
• Overproduction, underproduction of goods and services
• Misallocation of resources
• Poor response times
• Poor outcomes raise costs, lose customers
• E.g. World Call Pakistan failed to provide
managers with real-time data on customer
complaints, network performance, line outages,
etc.
88. 5) Competitive advantage
• Delivering better performance
• Charging less for superior products
• Responding to customers and suppliers in real time
• E.g. Dell: Consistent profitability over 25 years; Dell
remains one of the most efficient producer of PCs in
world.
• But Dell has lost some of its advantages to fast followers-
- HP
89. 6) Survival
• Information technologies as necessity of business
• May be:
• Industry-level changes, e.g. Citibank’s introduction of ATMs
• Governmental regulations requiring electronic record-keeping
• E.g. NADRA
90. The Interdependence Between Organizations and Information Technology
There is a growing
interdependence
between a firm’s
information systems
and its business
capabilities. Changes
in strategy, rules, and
business processes
increasingly require
changes in hardware,
software, databases,
and
telecommunications.
Often, what the
organization would like
to do depends on what
its systems will permit
it to do.
91. General System Model of the Firm &
Supply Chain Management
Chapter SIX
Enterprise Resource Planning
93. The General Systems Model of the Firm
• Physical resource flow includes personnel, material,
machines, and money.
• Virtual resource flow includes data, information, and
information in the form of decisions.
94. The General Systems Model of the Firm
• Firm’s control mechanism include
• Performance standards to meet if the firm wants to achieve
overall objectives.
• Firm’s management.
• Information processor that transform data into
information.
• Feedback loop is composed of the virtual resources.
95. The Firm in Its Environment
• Environmental elements are organizations and
individuals that exist outside the firm and have a
direct or indirect influence on it.
• Such as suppliers, customers, labor unions, financial
community, stockholders and owners, competitors, and
governments.
• Global community is the geographic area where the
firm performs its operations.
97. Managing the Physical Resource Flows–
Supply Chain Management
• Supply chain is the pathway that facilitates the flow
of physical resources from suppliers to the firm and
then to customers.
• Supply chain management manages the resources
through the supply chain to ensure timely and
efficient flow.
98. Supply Chain Management Activities
• Forecasting customer demand
• Scheduling production
• Establishing transportation networks
• Ordering replenishment stock from suppliers
• Receiving stock from suppliers
99. Supply Chain Management Activities (Cont’d)
• Managing inventory–raw materials, work-in-process,
and finished goods
• Executing production
• Transporting resources to customers
• Tracking the flow of resources from suppliers, through
the firm, and to customers
100. Supply Chain Management
• Firm’s information systems can be used to perform
the supply chain activities.
• Electronic systems provide the ability to track the flow
of the resources as it occurs.
• Is a crucial aspect of a firm’s ERP system.
101. Competitive Advantage
• Competitive advantage refers to the use of information to gain
leverage in the marketplace.
• Uses virtual as well as physical resources.
• Is used to meet the strategic objectives of the firm.
102. Porter’s Value Chain Model &
System Development Life Cycle
Chapter SEVEN
Enterprise Resource Planning
103. Porter’s Value Chains
• Value chain is created to achieve competitive advantage.
• Consists of the primary and support activities that contribute to margin.
• Margin is the value of the firm’s products and services minus their
costs, as perceived by the firm’s customers.
• Increased margin is the objective of the value chain.
105. Porter’s Value Activities
• Primary value activities manage the flow of physical resources
through the firm.
• Support value activities include the firm’s infrastructure.
• Each value activity includes purchased inputs, human resources, and
technology.
106. Expanding the Scope of the Value Chain
• Interorganizational system (IOS) is the linking of the
firm’s value chain to those of other organizations.
• Business partners are the participating firms in the
IOS.
• Value system is the linking of the firm’s value chain
with those of its distribution channel members.
107. The Systems Approach
• John Dewey identified three series of judgments involved in
adequately resolving a controversy:
• Recognize the controversy.
• Weigh alternative claims.
• Form a judgment.
• During the late 1960s/early 1970s, interest in systematic problem
solving strengthened.
• Systems approach—a series of problem-solving steps that ensure the
problem is first understood, alternative solutions are considered, and
the selected solution works.
110. Each Part of the System Is Analyzed in Sequence
111. Systems Development Life Cycle
• Methodology is a recommended way of doing
something.
• Systems development life cycle (SDLC) is an
application of the systems approach to the
development of an information system.
• Traditional SDLC stages are:
• Planning
• Analysis
• Design
• Implementation
• Use
115. Process Modelling, Process Improvement
and ERP Implementation
Chapter EIGHT
Enterprise Resource Planning
116. Introduction
• Tools that can be used to describe business processes
• Flowcharts, event process chains
• Not specific to ERP
• Can help managers identify process elements that can be improved
• Role of process-modeling tools in ERP implementation projects
117. Process Modeling
• Business processes can be quite complex
• Process model: any abstract representation of a process
• Process-modeling tools provide a way to describe a business process
so that all participants can understand the process
118. Process Modeling (cont’d.)
• Advantages of process models
• Graphical representations are usually easier to understand than written
descriptions
• Provide a good starting point for analyzing a process
• Participants can design and implement improvements
• Document the business process
• Easier to train employees to support the business process
119. Flowcharting Process Models
• Flowchart
• Any graphical representation of the movement or flow of concrete or abstract
items
• Clear, graphical representation of a process from beginning to end
• Uses a standardized set of symbols
• Process mapping
• Often used interchangeably with flowcharting
• Specifically refers to activities occurring within an existing business process
121. Fitter Snacker Expense Report Process
• Maria, Fitter Snacker salesperson
• Completes a paper expense report after travel
• Makes a copy for her records
• Attaches receipts for any expenses over $25
• Mails it to her zone manager at the branch office
• Kevin, zone manager
• Reviews expense report
• Approves report or mails it back to Maria asking for explanation, verification,
or modification
• After approval, mails it to corporate office
122. Figure 7-2 Partial process
map for Fitter Snacker
expense-reporting process
123. Fitter Snacker Expense Report Process
(cont’d.)
• Process at corporate office
• Accounts payable (A/P) clerk
• Process boundaries define:
• Which activities are to be included in the process
• Which activities are considered part of environment—external to process
• All processes should have only one beginning point and one ending
point
• Decision diamond asks a question that can be answered with “yes” or
“no”
124. Extensions of Process Mapping
• Hierarchical modeling: ability to flexibly describe a business process
in greater or less detail, depending on the task at hand
• Modeling software that supports hierarchical modeling
• Provides user the flexibility to move easily from higher-level, less detailed
views to the lower-level, more detailed views
126. Extensions of Process Mapping (cont’d.)
• Deployment flowcharting
• Swimlane flowchart
• Depicts team members across the top
• Each step is aligned vertically under the appropriate employee or team
• Clearly identifies each person’s tasks in the process
127. Figure 7-4 Deployment, or swimlane, flowcharting of the Fitter’s expense report process
128. Process Improvement
• Value analysis
• Each activity in the process is analyzed for the value it adds to the product or
service
• Value added is determined from the perspective of customer
• Real value: value for which the customer is willing to pay
• Business value: value that helps the company run its business
• No value: an activity that should be eliminated
129. Evaluating Process Improvement
• Disrupting the current process to make changes can be costly and
time consuming
• Dynamic process modeling takes a basic process flowchart and puts it
into motion
• Uses computer simulation techniques to facilitate the evaluation of proposed
process changes
• Computer simulation
• Uses repeated generation of random variables that interact with a logical
model of the process
• Predict performance of the actual system
131. Introduction
• An Enterprise Resource Planning (ERP) system allows a company to
accomplish tasks that cannot be done well, if at all, without such a
system
• Traditionally:
• ERP systems have been software applications that are run on a company’s
own computer systems

132. Introduction (cont’d.)
• Technologies, such as radio frequency identification (RFID), are
increasing the amount of data that is contained in ERP systems
• Business intelligence technologies are turning data in ERP systems
into valuable information
• Cloud computing and mobile technologies are changing where ERP
data is stored and how it is delivered
133. Radio Frequency Identification (RFID)
Technology
• Radio frequency identification technology
• Known commonly as RFID
• Becoming an increasingly efficient tool for tracking items through a supply
chain
• RFID device
• Can be attached to products
• A small package (or tag) made up of a microprocessor and an antenna
134. Radio Frequency Identification (RFID)
Technology (cont’d.)
• RFID reader
• Can determine location of an item with an RFID tag
