CHAPTER 1: Information Systems in Business

Explain information technology’s role in business: 


 IT is critical to all businesses, as it:
Reduces costs, 
Improved productivity 
Generates growth,
An enabler to support the business
Assists with efficiency
    IT solutions have the ability to improve customer service, finance, sales and marketing, operations management and human resources. 
    How IT can benefit all parts of a business


    Describe how you measure success?
    Efficiency:
    Effectiveness
    Drucker 'Do things right' 

    Focuses on the actual technology

    How it runs!?

    Measures the performance of the IT system, including Speed and availability, Information accuracy, Web traffic and Response time

    Benchmarks: Baseline values the system seeks to obtain

    Benchmarking: Continually measuring system results with benchmarks- and identifying improvements

    Drucker: 'Do the right things' 

    Focus on the business goals, strategies and objectives

    The impact IT has on business processes and activities 

    Includes usability, customer satisfaction, conversion rates, financial etc

    Set the right goals to ensure these are achieved 

    Mean time to repair: how long it takes to resolve an outrage

    First fix rate: The percentage of incidents that are correctly repaired the first time

    Change Success rate: % (& number for scope) of changes that are successfully deployed without creating an incident 

    Server to System Administration Ratio: Number of servers that can be handled by an administrator (high performers= 1:125, medium/low performers= 1:25)



    List and describe each of the forces in Porter’s Five Forces Model:


    5 Forces Model- evaluating business segments
              Determines the relative attractiveness of an industry




          Buyer Power:
    High: when buyers have many choices of whom to buy from
    Low: when their choices are few
    Reduce buyer power through loyalty programs!!
    Reward customers based on the amount of business they do within a particular organization
    Technology helps- make business more accessible eg websites


          Supplier Power
    High: when one supplier has a concentrated power over an industry (many buyers- few choices to choose from)
    Low: when there are many suppliers (buyers have a wide choice)


    Supply chain: Power is often with supplier: 





    Threat of substitute products or services
    High: when there are many alternatives eg butter, spread, magarine
    Low: when there are few alternatives eg specific medicines, or specific medical equipment
    Switching costs: costs (not always financial) that can make customers reluctant to switch eg switching cost of supplier with specific company or industry knowledge can be very high, Eg banks getting rid of fees

          Threat of new entrants
    High: when it is easy for new entrants to enter a market eg online bike sales
    Low: when there are significant entry barriers eg new telecommunications company
    Entry barrier: a product or service that customers have come to expect and must be offered to compete and survive eg high entry cost for new car manufacturer

             
          Rivalry amongst existing competitors:
    High: when competition is fierce in a market
    Low: when competition is more complacent
    Describe the relationship between business processes and value chains


    VALUE CHAINS ANALYSIS
      
          Value creation is the result of effective business processes and efficient value chains
    Business process:
    A standardized set of activities that accomplish a specific task
    Value chain: 
    Views an organization as a series of processes, each of which adds value to the product or service
    Primary value activities 
    Acquire raw materials and manufacture, deliver, market, sell and provide after sales services
    Support value activities: 
    Support the primary value activities 
    Porters Value Chain Analysis






    Compare Porter’s three generic strategies

    3 generic strategies creating a business focus:

    -          Follow one when entering a new market
    o   Broad cost leadership
    Eg antivirus or itunes (not having to buy entire CD)
    o   Broad differentiation
    Eg- apple- different to PC, or Amazon- buying books online, or buying Dell computers online
    o   Focused strategy
    Eg Iphones and Apple Computers

    Example of use of Porters 3 generic strategies
