Designer Alex's firm draws the plant room in their own template, with their own naming. The steel firm uses its own grid. The M&E firm uses another.
Made to the rules

Now I'm being made, on Alex's screen, before anyone else sees me. Give me a proper label: a name, what I can be used for, and which version I am.
The wrong way
Drawing 042, the drainage layout, exists as four files: 042_FINAL, 042_FINAL_v2, 042_latest, 042_latest USE THIS.
Rex, the assistant engineer, picks "latest USE THIS". It feels the most confident.
Put the drawings together and the plant room is 300 metres away, in a field. The cow is unimpressed.
It turns out "latest USE THIS" was the oldest of the four.
Sam, the firm's information manager, finds the project's rulebook.
Sam: Did anyone read the rules?
Alex: We've always done it this way.
Four files called FINAL, three grids, one cow, and a plant room in a field.
+2 weeks on the back alley's bill: House rules instead of the project's rules: drawings that don't line up, and the wrong 042 picked from four.
