Quality Is a Sequence of Small Checks

Quality is sometimes treated as a final inspection. By then, many mistakes have become expensive.

I prefer a sequence of smaller checks. A schema checks the shape of content while it is being prepared. A unit test checks a domain rule close to its code. A build checks whether routes and references resolve. A browser test checks the experience a visitor receives. A screenshot review catches visual problems that assertions cannot describe.

No single check is enough. Passing types cannot approve a personal claim. A visual review cannot prove that a hidden feed excludes drafts. The checks work because each has a narrow job.

The same idea applies outside software. Good work is easier when feedback arrives near the decision that created the risk.
