Editing Outline of software engineering (section)

== Software applications ==
[[Software]] engineers build [[software]] ([[Application 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.

*[[Engineering]] All traditional engineering branches use software extensively. Engineers use spreadsheets, more than they ever used calculators. Engineers use custom software [[tool]]s 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 document]]s 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.
