What is Software Engineering?

Software Engineering

• Classic Definition (1969)

The establishment and use of sound engineering
principles in order to obtain economically
software that is reliable and works efficiently
on real machines.

• IEEE Definition (1993)

Software Engineering (1) The application of a
systematic, disciplines, quantifiable approach to
the development, operation, and maintenance of
software that is the application of engineering
to software. (2) The study of approaches as in
(1).

Evolving Role of Software

• Early Years
• Batch orientation
• Custom software
• Second Era
• Multi-user, Real-time
• Database
• Product software
• Third Era
• Distributed systems
• Low cost hardware

• Fourth Era
• Desktop systems
• Object Oriented Technologies
• Expert Systems
• AI, neural networks
• Parallel computing
• Network computers

Ongoing Problems

• Hardware advances outpace ability to build
  software to tap potential
• Ability to build new programs cannot meet demand
  for new programs, nor do we build fast enough to
  meet business and market needs
• Widespread use of computers has made society
  increasingly dependent
• Struggle to build software with high reliability
  quality
• Ability to support and enhance programs is
  threatened by poor design and few resources
