Software engineering is the branch of engineering concerned with the systematic design, development, testing and maintenance of computer software, applying engineering discipline such as specification, design review, testing and version control to a medium that has no physical mass and can be copied without cost. The term and the formal discipline date to the late 1960s, when the growing size and unreliability of software systems prompted engineers to argue that writing software needed the same rigor as building a bridge.
Facts
Origin YearThe term software engineering was coined for the 1968 NATO Software Engineering Conference in Garmisch, West Germany. Core ConcernThe systematic design, development and maintenance of computer software. 1 Core PrincipleThe IEEE Standard Glossary of Software Engineering Terminology defines the field by its discipline: the application of a systematic, disciplined, quantifiable approach to the development, operation and maintenance of software, treating programming as an engineering practice rather than a craft. 2 FAQs
Is software engineering the same as computer science?
No, though the two overlap heavily. Computer science studies computation itself, algorithms, data structures, theory of computation and how computers process information. Software engineering applies engineering discipline, systematic design, testing, maintenance and process management, to building software that works reliably at scale over its whole lifecycle. A computer scientist might prove an algorithm's properties; a software engineer builds, tests and maintains the system that uses it in production.

Open Questions (1 open question)
Is software engineering genuinely a form of engineering in the licensed-profession sense, and should software engineers be licensed as Professional Engineers the way civil or electrical engineers are?
Wikipedia's software engineering article records that "the NCEES began offering a Professional Engineer exam for Software Engineering in 2013...NCEES ended the exam after April 2019 due to lack of participation. Mandatory licensing is currently still largely debated, and perceived as controversial." The same article notes the ACM and IEEE Computer Society examined licensing in the 1990s and concluded it was inappropriate for industrial practice, a conclusion the article says was not universally accepted.
What would resolve this A revival of the licensing exam with sustained participation, or a clear professional consensus statement from ACM/IEEE Computer Society settling whether licensure suits the field, neither of which exists yet.

Dissenting Readings (1 dissenting reading)
Description
After the ACM and IEEE Computer Society jointly concluded in the 1990s that licensing software engineers as Professional Engineers was inappropriate for the professional industrial practice of software engineering, Knight and Leveson published a 2002 analysis of the licensing question that Wikipedia's software engineering article describes as "a more balanced analysis of the licensing issue," implying the 1990s conclusion was not the last word and that a case for licensing remained live.
