    A set of interrelated components

    That interact

    To achieve a goal

    SYSTEMS, DATA, AND INFORMATION

    Every organization has goals. The subsystems should be designed to

    maximize achievement of the organizations

    goals. Even to the detriment of the subsystem itself.

    EXAMPLE: The production department (asubsystem) of a company might have to

    forego its goal of staying within its budget inorder to meet the organizations goal ofdelivering product on time.

    SYSTEMS, DATA, AND INFORMATION

    The systems concept encourages integration(i.e., minimizing the duplication of recording,storing, reporting, and processing).

    Data are facts that are collected, recorded,stored, and processed by an information system.

    Organizations collect data about:

    Events that occur Resources that are affected by those events

    Agents who participate in the events

    An AIS is a system that collects, records,stores, and processes data to produceinformation for decision makers.

    It can: Use advanced technology; or

    Be a simple paper-and-pencil system; or Be something in between.

    WHAT IS AN AIS?

  • 8/2/2019 Rais11_ch1

    12/37

    The functions of an AIS are to: Collect and store data about events,

    resources, and agents.

    Transform that data into information thatmanagement can use to make decisionsabout events, resources, and agents.

    Provide adequate controls to ensure that the

    entitys resources (including data) are: Available when needed

    Accurate and reliable

    ROLE OF THE AIS IN THE VALUE CHAIN

    Thats true, but werecomfortable with thatbecause of the value-

    carried out.

    An organizations value chain can beconnected with the value chains of its

    customers, suppliers, and distributors.

    ROLE OF THE AIS IN THE VALUE CHAIN

    Good AIS value chain:

    UPS spends over $1 billion a year on

    information systems resulting in greatercustomer control over delivery, higher driverproductivity, and lower costs.

    Bad AIS value chain: Limited Brands tangled integration of over 60

    incompatible information systems resulted in 400trailers trying to jam into a 150 trailer lot.

    Michael Porter suggests that there are twobasic business strategies companies canfollow:

    Product-differentiation strategy

    Low-cost strategy

    THE AIS AND CORPORATE STRATEGY

  • 8/2/2019 Rais11_ch1

    33/37

    Porter also argues that companies mustchoose a strategic position among threechoices:

    Variety-based strategic position

    THE AIS AND CORPORATE STRATEGY

    Offer a subset of the industrysproducts or services.

    EXAMPLE: An insurance companythat only offers life insurance asopposed to life, health, property-casualty, etc.

  • 8/2/2019 Rais11_ch1

    34/37

    Porter also argues that companies mustchoose a strategic position among threechoices:

    Variety-based strategic position

    Needs-based strategic position

    THE AIS AND CORPORATE STRATEGY

    Serve most or all of the needs of a particular group of

    customers in a target market. EXAMPLE: The original Farm Bureau-based

    insurance companies provided a portfolio of insuranceand financial services tailored to the specific needs of

    farmers.

    Porter also argues that companies mustchoose a strategic position among threechoices:

    Variety-based strategic position

    Needs-based strategic position

    Access-based strategic position

    THE AIS AND CORPORATE STRATEGY

    Serve a subset of customers who differ from others interms of factors such as geographic location or size.

    EXAMPLE: Satellite Internet services are intended

    primarily for customers in rural areas who cannot getDSL or cable services.

    Porter also argues that companies mustchoose a strategic position among threechoices:

    Variety-based strategic position

    Needs-based strategic position

    Access-based strategic position

    These strategic positions are notmutually exclusive and can overlap.

    The growth of the Internet has profoundlyaffected the way value chain activities areperformed: Inbound and outbound logistics can be streamlined for

    products that can be digitized, like books and music. The Internet allows companies to cut costs, whichimpacts strategy and strategic position.

    Because the Internet is available to everyone, intenseprice competition can result. The outcome may be that

    many companies shift from low-cost to product-differentiation strategies. The Internet may impede access-based strategic

    positions.
