Chapter 1
MORRES LAW- the number of transistors per square inch on an integrated chip doubles every
18 months because of this the cost of data communications is essentially zero
Future business professionals need to be able to assess, evaluate, and apply emerging
information technology to business
Soft skills/ non-routine skills - critical thinking/abstract reasoning , collaboration, systems
thinking (connecting the dots, putting it all together), ability to experiment
Abstract reasoning: the ability to make and manipulate models
Collaboration: is the activity of two or more people working together to achieve a
common goal, result or work product
Systems thinking: the ability to model the components of the system, to connect the inputs
outputs among those components into a sensible whole that reflects the structure and
dynamics of the phenomenon observed.
Ability to experiment: making a resonated analysis of an opportunity, envisioning
potential solutions, evaluating those possibilities, and developing the most promising
ones, consistent with the resources you have.
Components of an information system:
Hardware
Software
Data
Procedures
People
IT- information technology: refers to the products, methods, inventions and stands that are
used for the purpose of producing information (hardware, software, date)
MIS- management information system: management and use of information systems that help
businesses achieve their strategy
Chapter 2:
Business process- a network of activities for accomplishing a business function
BPMN- an internal standard for creating business process models
Activities: specific tasks that need to be accomplished as part of the process
Data flow: movement of data from one activity to another (marked by a dashed line)
Repository: a collection of data that is stored within the business process
Sequence flow: solid lines between activities
Why do businesses model their processes: be more efficient and more effective
Effective: one that enables the organization to accomplish the businesses strategy
Efficient: is the ratio of benefits to costs
What data characteristics are necessary for quality information?
Accurate
Timely
Relevant
Just barely sufficient
Worth its cost
Chapter 3

Competitive forces
Competition from vendors of substitutes-(lower price and perceived benefits the same)
Competition form new competitors-(barriers to entry, capital requirements, non-capital
resources)
Competition from existing rivals- (price, quality, innovation, marketing)
Bargaining Power Forces
Bargaining power of suppliers
Bargaining power of customers
4 competitive strategies-
Cost Differentiation
Industry-wide Lower cost across the industry Better product/service across
the industry
Focus Lower cost within industry segment Better product/service within an
industry segment
Value chain: network or value-creating activities (5 primary 4 support)
Primary activities: are business functions that relate directly to the production of the
organization’s products or services
Inbound logistics: receiving, storing, and disseminating inputs to the product
Operations/manufacturing: transforming inputs into the final product
Outbound Logistics: collecting, storing and physically distributing the product to
buyers
Sales/Marketing: inducing buyers to purchase the product and proving a means
for them to do so
Customer Service: assisting customers use of the product thus maintaining and
enhancing the product’s value
Support activities: business functions that assist and facilitate the primary activities
Can an IS give a company a competitive advantage?
Competitive advantage via product and business processes
Product Create a new
product or
service
Enhance
projects
or services
Differentiate
products or
services
Processes Lock in
customers
Lock in
suppliers
Raise barriers to
market entry
Establish
alliances
Reduce costs
Chapter 4
Client: computers for word processing, spreadsheets, database access and so forth
Servers: as their name implies, provide some service i.e process emails or websites
Client computers Private or public network (the internet) server computers (web,email,database)
Computer is sending message using a protocol, http, to get an html document
Input hardware: devices are the keyboard, mouse, scanner, microphone
Output hardware: video displays, printers, audio speakers, overhead projection
Virtualization: the process by which one computer hosts the appearance of many computers
PC virtualization: a personal computer host several different operating systems (pc or
mac)
Server virtualization: a server hosts on other server computers- virtual server on a server
