We also have lead inspectors for every trade. They perform monthly q c inspections on each inspector. Every other month they show us a PowerPoint presentation anonymously showing pictures of big items that were missed. The prospect that your boss will secretly come behind you at some point this month and check your work will keep most people honest. There is also the benefit of training and consistency among staff. We hate to hear, "well so and so lets me do that."
