In programming, it's move fast and break things. In aerospace, it's move slow and be methodical and never break things. I work in certification, and something as simple as re-painting interior sidewall panels requires something called an STC (supplemental type certificate) which requires updating manuals, burn testing representative samples of the painted panels, and design reports with constant communication with the local transport authority. I think the process is adequate, since we're dealing with machines in the sky, but it's the complete opposite of innovation.
