Challenge 3: Avoiding Format Drift in a Mixed-Suite Team — Solution Walkthrough

The recommended habit:

Agree explicitly, up front, on which file format is the genuine
"source of truth" for each shared document — for example, deciding
that a specific report stays in .docx because most of the team uses
Word, with LibreOffice users treating their own edits as needing to
be saved back into that same format every time, rather than everyone
saving in whatever format their own software happens to default to.

Why "just let everyone save in whatever they're using" is risky:

Without an explicit agreed format, a document can silently drift
through several round-trips as different team members open and save
it in whichever format their own software prefers — one person's
LibreOffice session saving it as .odt, the next Word user converting
it back to .docx, and so on. Each individual round-trip might only
carry a small risk on its own (per this chapter's own "usually
survives cleanly, some specific things shift" framing), but repeated,
uncoordinated round-trips across a document's whole editing history
compound that risk unnecessarily — and nobody involved would have a
clear, shared understanding of which version or format is actually
"the real one" at any given point.

WHY THIS WORKS AS AN ANSWER
------------------------------
This applies this chapter's own best-practices section directly to a
realistic team scenario — the risk isn't that any ONE format
conversion is likely to cause serious damage, it's that leaving the
choice of format uncoordinated across a whole team compounds a small,
per-conversion risk into a genuinely confusing, hard-to-track editing
history over time.
