What is Software Engineering?

• Textbooks tend not to give definitions, but
  instead spend their introductory chapters
  explaining characteristics of the discipline.
  Interesting phrases include
• A discipline whose aim is the production of
  quality software, delivered on time, within
  budget, and satisfying users' needs.
• The specification, development, management, and
  evolution of software systems.
• Designing and developing high-quality software

What is an MIS?

• MIS Definitions
• (management information systems) is a general
  term for the computer systems in an enterprise
  that provide information about its business
  operations http//www.whatis.com
• "concerning both the management of information
  technology and the use of information technology
  for managerial and organizational purposes - MIS
  Quarterly (http//www.misq.org)
• set of interrelated components that collect
  (retrieve), process, store, and distribute
  information to support decision making and
  control in an organization -http//saber.towson.e
  du/rosecky/m437txt.htm

Software Engineering Yesterday

• Software Engineering (term wasnt used)
• Computer Scientists (often did both hardware and
  software)
• Internet Forefathers
• Leonard Kleinrock, a computer scientist at UCLA,
  stands next to the refrigerator-sized computer
  that made the first-ever connection in 1969 to
  what was to become the Internet. (AP)
• The UCLA team of graduate students in 1969
  included future Internet leaders like Vinton
  Cerf, who later helped create the Internet's
  common language (TCP/IP), and the late Jonathan
  Postel, who pioneered its address system
• Robert Kahn computer language creator (TCP/IP)
• Lawrence Roberts - the designer and developer of
  ARPANET

Software Engineering Today and Tomorrow

• Information Technology Worker Shortage
• Companies in nearly every industry are reporting
  serious difficulty in finding and/or retraining
  qualified IT staff.
• The Bureau of Labor Statistics growth projections
  for the three core occupational classifications
  of IT workers (computer scientists and engineers,
  systems analysts, and programmers)
• indicate that between 1996 and 2006, the US will
  require more than 1.3 million new Information
  Technology workers, an average of about 137,800
  per year  

9
IT Market in the United States

• In 1996, there were 1.2 million IT jobs in the
  US, each paying an average of 55,000. IT
  salaries are increasing at an annual rate of 20,
  compared to 4 for other industries.
• A 1998 Virginia Tech study showed there are
  346,000 unfilled jobs in the IT sector
• U.S. high-tech employment approached 4.5 million
  in 1997. Demand for database administrators,
  computer support specialists, computer
  scientists, computer engineers, and systems
  analysts are all expected to more than double
  between 1996 and 2006
