MIS PPT for M.Sc.(Ca & It Student)

1. Chapter 2: Information Systems in
the Enterprise
1

2. Reading Notes for Chapter 2 in the textbook
The chapter introduces six types of information systems.
Figure 2.1 and table 2.1 give an overall picture of organizations
and how different types of information systems serve them.
Figure 2.2 depicts different types of information systems and how
they relate to one another (Figure 2.9 as well).
Section 2.2 examines information systems from a functional
view of an organization: Sales and marketing
systems, manufacturing and production systems, finance and
accounting systems, and human resources systems. Read this
section carefully to develop an understanding of how information
systems serve different functions of an organization.

3. Reading Notes for Chapter 2 in the textbook - Continued
Read section 2.3 carefully to understand integration of
functions and business processes. Figure 2.12 illustrates a
cross-functional business process. Pay also attention to
customer relationship management and enterprise systems
that are current trends in business. Contrast Figure 2.15 and
2.16. Extended enterprises and industrial networks are also
recent trends and would not be possible without the support
of information technology.

6. Four General Kinds of IS
 Operational-level systems
 support operational managers by monitoring
the day-to-day’s elementary activities and
transactions of the organization. e.g. TPS.
 Knowledge-level systems
 support knowledge and data workers in
designing products, distributing information, and
coping with paperwork in an organization. e.g.
KWS, OAS
 Management-level systems
 support the monitoring, controlling, decision-
making, and administrative activities of middle
managers. e.g. MIS, DSS
 Strategic-level systems
 support long-range planning activities of senior
management. e.g. ESS 6

7. A Framework for IS
(with respect to support provided)
• Executive Support Systems (ESS)
• Management Information Systems (MIS)
• Decision Support Systems (DSS)
• Knowledge Work Systems (KWS)
• Office Automation Systems (OAS)
• Transaction Processing Systems (TPS)
7

8. Transaction Processing Systems (TPS)
Computerized system that performs and records
the daily routine transactions necessary to
conduct the business; these systems serve the
operational level of the organization
• TYPE: Operational-level
• INPUTS: transactions, events
• PROCESSING: updating
• OUTPUTS: detailed reports
• USERS: operations personnel, supervisors
• DECISION-MAKING: highly structured
EXAMPLE: payroll, accounts payable 8

11. Office Automation Systems (OAS)
Computer system, such as word processing,
electronic mail system, and scheduling system,
that is designed to increase the productivity of
data workers in the office.
• TYPE: Knowledge-level
• INPUTS: documents, schedules
• PROCESSING: document management,
scheduling, communication
• OUTPUTS: documents; schedules
• USERS: clerical workers
EXAMPLE: document imaging system 11

12. Knowledge Work Systems (KWS)
Information system that aids knowledge workers in
the creation and integration of new knowledge in
the organization.
•TYPE: Knowledge-level
• INPUTS: design specifications
• PROCESSING: modelling
• OUTPUTS: designs, graphics
• USERS: technical staff; professionals
EXAMPLE: Engineering workstations
12

13. Decision Support Systems (DSS)
Information system at the management level of an
organization that combines data and sophisticated
analytical models or data analysis tools to support
semi-structured and unstructured decision making.
•TYPE: Management-level
• INPUTS: low volume data
• PROCESSING: simulations, analysis
• OUTPUTS: decision analysis
• USERS: professionals, staff managers
• DECISION-MAKING: semi-structured
EXAMPLE: sales region analysis 13

14. Characteristics of Decision-Support
Systems
1. DSS offer users flexibility, adaptability, and a
quick response.
2. DSS operate with little or no assistance from
professional programmers.
3. DSS provide support for decisions and problems
whose solutions cannot be specified in advance.
4. DSS use sophisticated data analysis and
modelling tools.
14

15. Management Information Systems
(MIS)
Information system at the management level of an
organization that serves the functions of planning,
controlling, and decision making by providing routine
summary and exception reports.
•TYPE: Management-level
•INPUTS: high volume data
•PROCESSING: simple models
•OUTPUTS: summary reports
•USERS: middle managers
•DECISION-MAKING: structured to semi-structured
EXAMPLE: annual budgeting
15

16. Characteristics of Management information
Systems
1. MIS support structured decisions at the
operational and management control levels.
However, they are also useful for planning
purposes of senior management staff.
2. MIS are generally reporting and control oriented.
They are designed to report on existing operations
and therefore to help provide day-to-day control of
operations.
3. MIS rely an existing corporate data-and data flows.
4. MIS have little analytical capability.
5. MIS generally aid in decision making using past
and present data.
6. MIS are relatively inflexible.
7. MIS have an internal rather than an external 16

17. Executive Support Systems (ESS)
Information system at the strategic level of an
organization that address unstructured decision
making through advanced graphics and
communications.
TYPE: Strategic level
• INPUTS: aggregate data; internal and external
• PROCESSING: interactive
• OUTPUTS: projections
• USERS: senior managers
• DECISION-MAKING: highly unstructured
EXAMPLE: 5 year operating plan

31. HOW INFORMATION SYSTEMS CAN
FACILITATE SUPPLY CHAIN
MANAGEMENT
Information systems can help participants in
the supply chain:
 Decide when and what to produce, store, and
move
 Rapidly communicate orders Track the status of
orders
 Check inventory availability and monitor
inventory levels
 Track shipments
 Plan production based on actual customer demand
 Rapidly communicate changes in product design 31

32. Enterprise Systems
 Firm wide information systems that
integrate key business processes so
that information can flow freely
between different parts of the firm.
