1) LO1 Describe some of the threats to security and privacy that information systems and the
Internet can pose:
2) LO2 Discuss the expanding role and benefits of information systems in business and
industry.
3) LO3 Identify the major steps of the systems development process and state the goal of
each:
Systems investigation – Understand the problem
System analysis – Determines what must be done to solve the problem
System design – The solution is planned out
System implementation – The solution is built or bought and replaces the old system
Systems maintenance and review – The new system is evaluated
4) LO4 List the components of a computer-based information system:
Hardware, software, telecommunications, databases, people, procedures
5) LO5 Identify the basic types of business information systems and discuss who uses
them, how they are used, and what kinds of benefits they deliver.
-
Enterprise Systems: Transaction Processing Systems (TPS)
and Enterprise Resource Planning (ERP)
e-commerce Any business transaction executed electronically between companies
(business-to-business), companies and consumers (business-to-consumer), consumers and
other consumers (consumer -to-consumer), business and the public sector, and consumers
and the public sector.
mobile commerce (m-commerce) Conducting business transactions electronically using
mobile devices such as smartphones
electronic business (e-business) Using information systems and the Internet to perform all
business-related tasks and functions.
Benefits: A TPS can speed business activities and reduce clerical costs. Businesses can use
the data stored in these systems to help managers make better decisions, whether in
human resource management, marketing or administration
-
A management information system (MIS) is an organized collection of people, procedures,
software, databases and devices that provides routine information to managers and
decision makers. An MIS focuses on operational efficiency. Output of TPS is input to MIS.
Used for managerial reports
-
Decision support system (DSS). is an organized collection of people, procedures, software,
databases and devices that support problem-specific decision making.
The focus of a DSS is on making effective decisions. Whereas an MIS helps an organization
‘do things right’, a DSS helps a manager ‘do the right thing’.
-
knowledge management systems (KMSs), an organized collection of people, procedures,
software, databases and devices to create, store, share and use the organization’s
knowledge and experience.
-
artificial intelligence (AI) The ability of computer systems to mimic or duplicate the functions
or characteristics of the human brain or intelligence.
Expert systems give the computer the ability to make suggestions and act like an expert in a
particular field
knowledge base A component of an expert system that stores all relevant information,
data, rules, cases and relationships used by the expert system.
virtual reality The simulation of a real or imagined environment that can be experienced
visually in three dimensions.
6) LO6 Name the components of an information system and describe several system
characteristics.
-
Input
Processing
Output
Feedback
System characteristics:
- Variances from the standard are determinants of system performance.
- Efficiency is a measure of what is produced divided by what is consumed.
- Effectiveness is a measure of the extent to which a system achieves its goals. It can be
computed by dividing the goals actually achieved by the total of the stated goals.
