I posted this on one of the other forums, but re-posting here in hopes of getting a reply:
Question:
My company builds large, commercial HVAC units. The process map is:
Assembly Station 1
Assembly Station 2
Assembly Station 3
Assembly Station 4
Assembly Station 5
Assembly Station 6
Assembly Station 7
Assembly Station 8
Assembly Station 9
Assembly Station 10
Functional Testing (100% of completed units)
Close
My Quality Technician conducts an AQL sample (12%) in the Assembly Stations. He also conducts end-of-line audits (12%) on completed units.
We currently report the audit results and test results as three separate first-pass yield numbers. What I would like to do is also combine them into a single Rolled Throughput Yield. My question is whether it would be reasonable to do so since some data is sampled and some is 100%?
Thanks in advance.
