Software Engineering
Noun · Development
Definitions
The disciplined application of engineering principles to the design, development, testing, deployment, and maintenance of software systems — emphasizing reliability, scalability, and team collaboration over time. Distinguished from mere programming by its focus on long-term maintainability, process rigor, and operating at scale.
In plain English: The practice of building software systematically and reliably, treating it as an engineering discipline rather than just writing code.
Example: "Programming is writing code that works; software engineering is writing code that still works in three years when the team has tripled."
