IT Careers • Economic downturns have affected all job sectors, including IT • Rising labor costs are pushing jobs to India, the Middle East, and Asia-Pacific countries • However, IT employment opportunities are strong, with new jobs emerging daily • Shortages of IT personnel are frequent • The long-term job outlook is positive and exciting 38

IT Careers 39

IT Careers • Job increases will be driven by… • Rapid growth in computer system design and related services • The need to backfill positions • Information sharing and client/server environments • The need for those with problem-solving skills • Falling hardware and software prices, which will fuel expanded computerization of operations 40

The IS Function • The IS function is… • A major functional area of business • An important contributor to operational efficiency, employee productivity, morale, customer service and satisfaction • A major source of information and support for decision making • A vital ingredient in developing competitive products and services in the global marketplace • A dynamic and challenging career opportunity • A key component of today’s networked business 41

System Concepts: A Foundation • System concepts help us understand… • Technology: hardware, software, data management, telecommunications networks • Applications: to support inter-connected information systems • Development: developing ways to use information technology includes designing the basic components of information systems • Management: emphasizes the quality, strategic business value, and security of an organization’s information systems 42

What is a System? • A system is… • • • A set of interrelated components With a clearly defined boundary Working together To achieve a common set of objectives By accepting inputs and producing outputs In an organized transformation process 46

Basic Functions of a System • Input • Capturing and assembling elements that enter the system to be processed • Processing • Transformation process that converts input into output • Output • Transferring transformed elements to their ultimate destination 47

Cybernetic System • All systems have input, processing, and output • A cybernetic system, a self-monitoring, selfregulating system, adds feedback and control: • Feedback is data about the performance of a system • Control involves monitoring and evaluating feedback to determine whether a system is moving toward the achievement of its goal 48

A Cybernetic System 49

A Business as a System 50

Other System Characteristics • If a system is one of the components of a larger system, it is a subsystem • The larger system is an environment • Several systems may share the same environment • Some may be connected via a shared boundary, or interface • Types of systems… • Open • Adaptive 51

Components of an IS 52
