      • Entry-level: help desk, PC technician
      • II. Centralization or Decentralization? (p.519)
      • 1. Hardware
      • Centralizing hardware
        • Share hardware such as large computer, printer and so on.
        • Less duplication of hardware, software, data and MIS personnel.
        • More efficient use of hardware
        • User access control
      • Decentralizing hardware
        • Price ($50,000 per MIPS vs.. $50 per MIPS)
        • Avoid total breakdown
        • Personalized equipment
      • 2. Software
      • Centralizing software
        • Standardization and compatibility
        • Easier to install and upgrade
        • A certain number of licenses shared by more users
        • Buying discount
      • Decentralizing software
        • Speed
        • Flexible to requirement of users
      • 3. Data
      • Centralizing data
        • Easy to share data (concurrent access, data integrity, security control and monitoring access and usage)
        • Easy to backup and recover
      • Decentralizing data
        • Faster data access (sometimes through data replication)
        • Complete control of own data
        • Easy access since users know what data they have and where data is located.

        • Better communication to users
        • Different career path
      • 5. Client/Server model combines both
      • Items on server tend to be centralized and gain efficiencies from large scale of operation
      • Items on client tend to be decentralized and flexibility
      • III. Outsourcing Computer Facilities and Services
      • (p.517)
      • Advantages
        • Professional development teams
        • Minimize management of IT development issues
        • Easy to control costs
      • Disadvantages
        • Possible loss of control
        • Security issues
        • Who identify long-term competitive advantages
        • Possible higher costs: your cost + profit margin
