I have worked in companies that it was true. And others where it was not. Even in one company we moved from not true to true, in about 8 years (there was of course not a hard cut).

The companies where it was not true, was a pleasure to work in. The management, from C-suits downwards knew what they were doing. In the others, it was a total chaos.

Of course, if everything is fixed with duct tape, you need firemen ready to act. If everything is solid and robust, there can be small outages, but nothing too critical.
