Supplier Quality & Inspection
Use requirements, supplier evidence and verification to manage purchased quality.
Quality note: real acceptance criteria, test methods and sampling requirements come from applicable specifications, standards and qualified technical authority—not from generic web guidance.
What this topic covers
Use requirements, supplier evidence and verification to manage purchased quality.
Core testing ideas
Supplier quality starts with clear technical and documentation requirements.
Source inspection, certificates and receiving checks provide different evidence.
Supplier performance should be based on consistent measures rather than anecdote.
Measurement and method limits
SPC and capability metrics describe process behaviour, while engineering specifications describe product requirements.
Evidence and traceability
Nonconformance, corrective action, audits and supplier controls close the loop when results do not meet expectations.
Using the result
Quality metrics should be defined consistently so improvement is real rather than a reporting artifact.
