Why Documentation Matters More Than You Think

Documentation is crucial in software engineering, accelerating development, clarifying complexity, and supporting sustainable systems. It encompasses tactical elements like READMEs and changelogs, as well as strategic components such as C4 models and Architecture Decision Records. DocOps treats documentation as code, integrating it into development workflows. Good documentation prevents knowledge silos, enables team autonomy, and reduces onboarding time. Neglecting it can lead to severe consequences, as seen in the Knight Capital incident where poor documentation contributed to a $440 million loss.
