What is an information system? - -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? - -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? - -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 - -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 - -ability to make and manipulate models
-systems thinking - -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 - -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 - -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) - -Provides a means to communicate with
others about process structure and possible changes in a business
-Swimlane format - -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) - -specific tasks that need to be accomplished as part of
the process
-Role - -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 - -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 - -represent the movement of data from one activity to another
-Process quality - -measured by process effectiveness and process efficiency
-effective business process - -one that enables the organization to accomplish its strategy
-efficiency - -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 - -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 - -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 - -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 - -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 - -Defines long term vision/direction
-value - -the amount of money that a customer is willing to pay for a resource, product, or
service
-margin - -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 - -network of value creating activities (5 primary and 4 support activities)
-primary activities - -business functions that relate directly to the production of the
organization's products or services
-support activities - -business functions that assist and facilitate the primary activities.
they contribute to margin and directly to the production, sale, and service of the product
(example: setting up contractual arrangements or negotiating prices)
