I remember joining the industry and switching our company over to full Continuous Integration and Deployment. Instead of uploading DLL's directly to prod via FTP, we could verify each build, deploy to each environment, run some service tests to see if pages were loading, all the way up to prod - with rollback. I showed my manager, and he shrugged. He didn't see the benefit of this happening when, in his eyes, all he needed to do was drag and drop, and load the page to make sure all is fine.

Unsurprisingly, I found out that this is how he builds websites to this day...
