Software Engineering: Design Principles and Development Methodologies

Status: public · Confidence: medium (0.865) · Basis: verified_sources

## TL;DR
Software engineering principles cover more than writing code: they include requirements, design, construction, testing, maintenance, configuration management, operations, security, process, quality, and professional responsibility.

## Core Explanation
SWEBOK gives a consensus-oriented map of the software-engineering body of knowledge. ISO/IEC/IEEE 12207 defines life cycle processes that organizations can tailor for acquisition, development, operation, maintenance, and retirement. Ethical practice matters because software decisions affect users, organizations, society, and the public interest.
