Regulatory Code List & Reference Update

Published • • 2 min read

A reference code list (MDN, MDS, etc.) is only trustworthy if it's rebuilt from the current authoritative source each time, not carried forward from the last version.

Converting a set of documents to Times New Roman and merging them into a single package looks like pure formatting work. Doing it properly meant going further: rebuilding the reference code list those documents relied on, rather than just cleaning up the font.

Merging is a chance to verify, not just tidy

When documents get merged into one package, it's tempting to treat the exercise as cosmetic, fonts, spacing, headers. But merging puts every referenced code and cross-reference side by side, which is exactly the moment to check whether they still match the current authoritative source.

The rebuild covered:
  • Comparing the existing checklist/instruction against the current regulation or process in practice
  • Correcting discrepancies found during the merge
  • Confirming the update against the source document or QMS procedure

The risk hiding behind a formatting task

An outdated checklist or work instruction being followed after the underlying regulation or process has changed is easy to miss when the visible work is "make it consistent." The formatting pass is a natural checkpoint to catch it, if the reference list gets rebuilt rather than just re-typed.

What the formatting pass actually delivered

Rebuilding the reference code list from the current authoritative source, correcting outdated entries along the way, meant the merged and reformatted package was accurate, not just consistent-looking.

The Real Takeaway

A reference code list is only trustworthy if it's rebuilt from the current authoritative source each time, not carried forward from the last version.

A formatting pass is a good opportunity to do that rebuild, but only if it's treated as more than a cosmetic exercise.
