The frame for this comparisonProduct data is a practice, not a project.
STEP can define what a complete record looks like on the day the model ships; keeping tens of thousands of records complete as rules tighten, standards revise and suppliers send new datasheets is a practice, not a project — so this comparison isn't about which system holds the record, it's about who does the upstream work of finding the values STEP's rules are waiting on.
01
Ground it
Mine every spec from every source.
Every value traced to a document you can open. The catalog is only as honest as what it was built from.
02
Align it
Aim the catalog at the buyer who actually buys.
Grounded data still loses if it answers questions nobody asked. Alignment is what turns specs into conversion.
03
Keep it alive
Product data is a practice, not a project.
Markets move, suppliers reissue, buyers change what they ask for. A catalog that is right in March is wrong by August unless something is watching.
