Outline of software engineering

See also: Index of software engineering articles

The following outline is provided as an overview of and topical guide to software engineering:

Software engineering – application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software; that is the application of engineering to software.

Technologies and practices

Skilled software engineers use technologies and practices from a variety of fields to improve their productivity in creating software and to improve the quality of the delivered product.

Software applications

Software engineers build software (applications, operating systems, system software) that people use.

Applications influence software engineering by pressuring developers to solve problems in new ways. For example, consumer software emphasizes low cost, medical software emphasizes high quality, and Internet commerce software emphasizes rapid development.

Engineers use custom software tools to design, analyze, and simulate their own projects, like bridges and power lines. These projects resemble software in many respects, because the work exists as electronic documents and goes through analysis, design, implementation, and testing phases. Software tools for engineers use the tenets of computer science; as well as the tenets of calculus, physics, and chemistry.

Disasters

Software has played a role in many high-profile disasters.

• Ariane 5 Flight 501
• Mars probe
• Denver International Airport
• TAURUS — UK share settlement system and dematerialised central share depository.
• Therac-25 — A radiation therapy machine responsible for six overdoses due to faulty software.
• Airbus A320 — The Airbus A320, while was controversial in software engineering circles, being the first civilian Fly-by-wire aircraft. In the Airbus flight control systems, the computer has the final say on all decisions, meaning the safety of passengers depends upon the accuracy of the software specification, and the competence of the engineering teams producing the (multiple, independent) software stacks. The Strasbourg A320 crash of Jan 21, 1992 is partially related to software in that poor user interface design was a contributing factor.
• Failure at Dharan — Patriot Missile clock issue.
