ISA 235 EXAM 1 MCGUIRE STUDY GUIDE
What is an information system? - Answer -A group of five integrated components that
interact to produce information: Hardware, software data procedures, people
What is the importance of information systems? what do they do? - Answer -Help
companies support, improve and reinvent business processes in their supply and value
chains. Help improve process efficiency. Help companies innovate through both
automation and integration. Help companies gain competitive advantages.
What is MIS? - Answer -Management information systems are information systems
used in business. The development and use of information systems that help achieve
their strategies. also a field of study on how to accomplish this.
difference between information technology and information systems - Answer -
information technology refers to the methods, inventions, standards, and products and
is not a system. Information systems is a system that is IT plus people and
procedures/processes that makes IT useful. You can buy IT, but not IS.
abstract reasoning - Answer -ability to make and manipulate models
systems thinking - Answer -ability to model the component of the system to connect the
inputs and outputs among those components. Also a way of approaching problems or
changes from a systems perspective.
Moore's law - Answer -The cost of computing, data communications and data storage
is essentially zero. This means the rise of a whole new kind of information industry.
business process - Answer -A set of linked activities that create value for accomplishing
a business function by transforming inputs into a more valuable output
business process modeling notation (BPMN) - Answer -Provides a means to
communicate with others about process structure and possible changes in a business
Swimlane format - Answer -a graphical arrangement in which all of the activities for a
given role (job type) are shown in a single vertical lane.
activities (in swimlane format) - Answer -specific tasks that need to be accomplished as
part of the process
Role - Answer -a subset of the activities in a business process that is performed by an
actor, which is a person, group, department, organization, or information system.
repository - Answer -a collection of data that is stored within the business process
(examples: computer databases or collections of files in the cloud or printed records)
, data flows - Answer -represent the movement of data from one activity to another
Process quality - Answer -measured by process effectiveness and process efficiency
effective business process - Answer -one that enables the organization to accomplish
its strategy
efficiency - Answer -the ratio of benefits to costs
(If there are 2 versions of a business process and one is more costly, you use the other.
Or if they are the same cost but 1 has more benefits, you use that one)
The five components of information systems - Answer -hardware, software, data,
procedures, people
-Hardware and people are actors in a business process
-Software and procedure components are both sets of instructors
-Software is instructions for hardware, and procedures are instructions for people
information - Answer -knowledge derived from data, which are records, facts, or figures
AND data that is given context or processed. It must be: accurate, timely, relavent,
sufficient, and worth the cost
(Example: average wage is knowledge that is derived from the data of individual wages)
difference between information and data - Answer -f it's in the mind of a human, it is
information. If it is on a piece of paper or on a digital screen, it is data.
competitive strategy - Answer -Formed from analysis of other structures of industries
and help organizations be effective. in order to maintain this competitive strategy,
organizations must understand their market and new technological up-comings
strategy - Answer -Defines long term vision/direction
value - Answer -the amount of money that a customer is willing to pay for a resource,
product, or service
margin - Answer -the difference between the value that an activity generates and the
cost of the activity (a business with a differentiation strategy will add cost to an activity
only as long as the activity has a positive margin)
value chain - Answer -network of value creating activities (5 primary and 4 support
activities)
primary activities - Answer -business functions that relate directly to the production of
the organization's products or services
