Information Systems
What is Information Technology (IT)?
• Consists of all the hardware and software that a firm needs to use in order to
achieve its business objectives
• Information technology is an important enabler of business success and
innovation
• IT Infrastructure
- Hardware
- Software
- Data (via "Data Management Technology")
- Networking & Telecommunications
What is an Information System (IS)?
• A group of interrelated components working to collect, process, store and
disseminate the information needed to support decision-making, coordination,
control and analysis in an organization.

Take-Aways from Case Examples
• Disney is trying to solve a problem of matching Supply and Demand; Improving
Customer Experience
• UPS is focused on efficiency and shifting some of the information input to the
customer; Improving Customer Experience and delivering at a competitive price
IT infrastructure:
• Set of physical devices and software required to operate enterprise
• Set of firm wide services including:
- Computing platforms providing computing services
- Telecommunications services
- Data management services
- Application software services
- Physical facilities management services
- IT management, education, and other services
^^^^^^^^^^^^^^^^^^^^^^^
IT Infrastructure has 7 main components:
- Computer hardware platforms
- Operating system platforms
- Enterprise software applications
- Data management and storage
- Networking/telecommunications platforms
- Internet platforms
- Consulting system integration services

Moore’s law and microprocessing power
- Computing power doubles every 18 months.
- Nanotechnology: May shrink size of transistors to width of several atoms.
- Contrary factors: Heat dissipation needs, power consumption concerns.
Law of Mass Digital Storage
- The amount of data being stored each year doubles
- Variants of Moore’s Law include: the number of transistors on a chip doubles ever 18
months; computing power doubles every 18 months; and the price of computing falls by half
every 18 months.
Metcalfe’s Law and network economics
- Value or power of a network grows exponentially as a function of the number of
network members
- As network members increase, more people want to use it (demand for network
access increases)
- Declining communication costs and the Internet
- An estimated 1.5 billion people worldwide have Internet access
- As communication costs fall toward a very small number and approach zero,
utilization of communication and computing facilities explodes
Computer Hardware Platforms
• Client machines
Desktop PCs, mobile computing devices – PDAs, laptops
• Servers
Blade servers: ultra-thin computers stored in racks
• Mainframes:
IBM mainframe equivalent to thousands of blade servers
