Hello, in practice what is typically the role of QAQC in equipment qualification? What are the other departmental roles? It's my understanding the QAQC role is to make sure that the testing is appropriate, adequate, and complete. During the protocol phase QAQC works with engineering and production to design tests. During the execution phase QAQC verifies that the testing was done per the protocol and all testing was complete and meets specs. Is this correct? Which department actually "owns" the validation? Thanks for your input.
