Execution absolutely is a problem. Being able to build something is 10% of the battle. Being able to build it well and reliably is the other 90%. A culture around building the proper tests, monitoring, and tooling to handle launches safely and plan rollouts goes a long way and most companies don't have any of that. The difference is stark even at large companies. Oncall shifts for friends at places like Amazon and Meta are nightmares of constant pages and stress. Oncall shifts for my friends at Google have tended to be far lower key, with dramatically fewer pages and more straightforward resolutions when issues appear.
