Quality concepts
Traceability
Also called: traceable
Traceability is the ability to follow a piece of finished work back through the chain that produced it — the approved submittal, the material and batch that went in, the inspection that passed it and the photo that recorded it. On a QC record it means any given assembly can be linked to the evidence that it was the right product, installed right, and checked. Without traceability the record is a pile of loose photos and forms; with it, one location resolves to its whole history.
Why it matters
When a product recall, a failed batch or a warranty question comes up, traceability is what tells you which installed work is affected and which is clear. Without it, one bad delivery means suspecting everything.
It is also what makes a turnover package believable. A reviewer who can pick a location and pull the submittal, the inspection and the tagged photo behind it is looking at a record that holds together, not a stack of paper that hopes not to be tested.
How it shows up on site
QR tags on the work and photos tied to a specific location and inspection, so a concealed assembly can be traced to the submittal it was built from and the check that passed it — long after the wall is closed.
Checklists that put traceability to work
Free, field-ready checklists, each with the photo every item needs before it can be submitted.

Knowing the term is step one. Proving it is the job.
RTI holds the submit button until every mandatory item is answered and the photos are attached, then chains the record so it can be proven untouched later.
