The purchasing decision
Create separate subsystem BOMs. For fluid parts, identify materials, plumbing and dispensing references; for spreading parts, identify feed, disc and drive assemblies. Keep each service kit tied to its documented maintenance task.
Keep these records
- Subsystem BOMs.
- Matching interfaces and wear criteria.
- Separate kit and restock records.
Give each record an owner and a revision or date. If a supplier proposes a different part or test condition, record it as an exception for review before treating the quotation as equivalent.
Turn the review into a sourcing request
Start with the linked component checklist, add the actual platform and part identity, and state quantity, destination and timing. List unresolved requirements explicitly so the first discussion can focus on those gaps.
