Yeah I don’t agree with never making the same mistake twice, especially for lower level employees. Deming in The New Economics points out that all processes in an organization have natural variation, so mistakes only have meaning if they go beyond that variation in their impact. So if your code is so fragile that it requires manual testing of every feature before deploying, it’s very likely that a junior employee will forget that testing step more than once, because the system has set them up to fail. Deming would suggest never blaming individuals, and instead measuring the process’s variation and working to reduce it, in this case by reducing code fragility or finding ways to automate or enforce the manual testing.
