1. Why Do Suppliers Use These Terms Differently?
Project terminology varies because sales teams, engineers, factories, and markets developed overlapping language for related products. In an RFQ, the phrase "touch panel vs touchscreen" must cover regional language without ambiguity. Some catalogs call sensor glass a touchscreen while others reserve that word for an LCD assembly. A familiar term can create a false sense of agreement during quotation.
Start with regional language. A useful review connects regional language with one drawing, one sample revision, and one test plan. Buyers should compare matching scope for regional language before price. A supplier should record every accepted deviation involving regional language for production and receiving inspection.
How should contracts define regional language?
- Record supplier wording
- Create project glossary
- Attach part list
- Reference drawings
| Buyer check | Evidence | Release rule |
|---|---|---|
| Record supplier wording | Controlled drawing | Scope and revision match |
| Create project glossary | Approved sample | Construction matches approval |
| Attach part list | Relevant test record | Method fits stated use |
| Reference drawings | Batch inspection record | Result meets agreed limit |
