- What is information?: Knowledge derived from data - Processed data - Data processed by summing, ordering, averaging, grouping, comparing, or other similar operations
Q2-6: How does competitive strategy determine business processes and the structure of information systems?
- When an organization selects a competitive strategy, it designs business processes that include and link value-generating activities. The processes themselves will determine the organization's IT requirements. It is therefore critical that businesses align their IT with their business objectives.
Ch 3: Deciding

Q3-1: The cost of the business process is?
- the cost of the inputs + the cost of the activities
Ch 2: Repository
A collection of something; a database is a repository of data, and a raw material repository is an inventory of raw materials
Ch 2: Business Processes

Q1-6: What are necessary data characteristics?
Accurate Timely - Available in time for its intended use Relevant - Data should be relevant both to the context and subject Just sufficient - Sufficient for the purpose for which it is generated Worth its cost
Ch 2: Value
Amount of money a customer is willing to pay for something
Q2-3: How does analysis of industry structure determine competitive strategy?
An organization responds to the structure of its industry by choosing a competitive strategy - An organization can focus on being a cost leader or it can focus on differentiating its products and services from competitors - The intensity of each of the five forces determines characteristics of the industry, how profitable it is, and how sustainable profitability will be
Ch 2: Customer Service
Assisting customers' use of the products and thus maintaining and enhancing the value of the product
Ch 3: Static Reports
BI documents that are fixed at the time of creation and don't change (printed sales analysis) (usually published as PDF documents)
Ch 2: Examples of forces strong and weak ( Five Forces )
Bargaining power of customers - A large account wants a greater share of profits (strong) - Response: Lower prices or diversify into a new market Threat of substitutions - Ebay offers a local delivery service (medium) - Response: offer differentiating services like shipping, transportation, or entertainment Bargaining power of suppliers - Were increasing the cost of self-driving vehicle chassis (weak) - Response: Buy from a different manufacturer Threat of new entrants - Uber starts offering mobile retail services (medium) - Response: Offer differentiating circumstances and enter other markets Rivalry - Amazon offers drone delivery (weak) - Response: offer additional services or create additional corporate partnerships
Ch 2: Activity
Business function that receives inputs and produces outputs (can be performed by a human, computer system, or both)
Ch 4: Hardware Components
Central processing unit (CPU) - "The brain of the computer" Computer with 2 CPUs is called a dual-processor Computer with 4 CPUs is called a quad-processor CPU works in conjunction with main memory - Reads data and instruction from memory and then stores the results of computations in main memory Main memory is sometimes called RAM (random access memory) Storage hardware = magnetic disks/hard disks to save info Solid state drives (SSD) stores data much faster than ^^
Q3-2: How do organizations use data warehouses and data marts to acquire data?
Data warehouse is the distributor and data mart is the retail store - The difference between data mart and data warehouse- think of data warehouse as distributor in supply chain. Data warehouse takes data from other data manufacturers (operational systems/other sources), and cleans, processes it, and places it on the "shelves" of the data warehouse. The data mart would be the retail store in this supply chain
Ch 2: Margin
Difference between the value that an activity generates and the cost of the activity
Ch 2: Information systems create competitve advantages either as part of a product or by prpviding support to a product
Example: car rental agency - Information system (IS) that provides information about the cars location and provides driving instructions to the destination is part of the car rental, and thus is part of the product itself
Ch 2: First Mover Advantage
Gaining market share by being the first to develop technology in a market segment, doesn't guarantee an advantage over rivals - In fact, can be detrimental because have to spend considerable resources on research and development to educate the public
Q1-4: How can you use the five component model?
Hardware,Software,Data,Procedures,People - Actors: Hardware, People - Instructions: Software, Procedures - Bridge: Data - Computer Side: Hardware, Software - Human Side: Procedures, People ( Automation moves work from human side to computer side ) ( Increasing degree of difficulty of change ) - Symmetric: Outer components take action, software are instructions for hardware and procedures are instructions for people, data bridges computer side to human side. Most important component in the five component model is people
Ch 2: Sales and Marketing
Inducing customers to buy the products and providing a means for them to do so
Q1-2: How will MIS affect me?
Job security - Only job security that exists is "a marketable skill and the courage to use it" Strong routine (Cognitive skills) Abstract reasoning - Construct a model or representation Systems thinking - Model system components and show how components inputs and outputs relate to each other Collaboration - Develop ideas and plans with others. Provide and receive critical feedback Ability to experiment - Create and test promising new alternatives, consistent with available resources Technology Skills Gap - Mismatch between the high levels of tech skills demanded by employers and the low level of tech skill held by employees As the price of computer technology plummets, the value of jobs that benefit from it increase dramatically
Ch 2: Second Mover Advantages
Many of the leading companies today did this - Gaining market share by following a pioneering company and imitating its products/services (reduces research and development costs)
Q2-2: What five forces determine industry structure?
Michael Porter: - Five forces model - Determine industry profitability: bargaining power of customers, threat of substitutes, bargaining power of suppliers, threat of new entrants, rivalry amongst existing firms - The intensity of each of the five forces determines characteristics of the industry, how profitable it is, and how sustainable profitability will be
Q2-4: How does competitive strategy determine value chain structure?
Organizations examine the structure of their industry and determine a competitive strategy Competitive strategy determines value chains determines business process Structure of business processes determines design of supporting information systems Industry structure > Competitive Strategy > Value Chains > Business Processes > Information Systems
