Years ago I was working in a company that was designing and manufacturing some state-of-the-art microwave communications equipment. The design engineers released the design for production, at which point we spent 6 months attempting to "tweak" the first article unit to working order. Finally, after falling 3 months behind schedule it was decided that we should get the "engineering" models out and review the differences. Guess what, the engineering models didn't work either. Then both units were taken back to the Engineering Lab where it was found that both the FA and the engineering model worked well in the lab.
Root cause: Uncalibrated equipment in the lab.
This one project was enough to cause management to re-evaluate Design Engineering's former stand that their equipment did not require calibration.
