Ask HN: How does your organisation train programmers?
In High Output Management , Andy Grove stresses the importance of training staff in their duties. In fact, he lists it as one of only two methods of improving performance (the other pertaining motivation). Of course, any time we do anything we "train" ourselves in it and get better at it, but if this was the only training one had, it would be what Grove discourages and refers to as "the customer paying the tuition." So, clearly, Grove refers to actual, explicit training that is not simply learning on the job. He never goes into detail about how to do this; I assume because it's such an obvious, in-grained thing in all other disciplines that it needs no details. Yet I've never seen it done in software engineering. So how does your organisation do it? Why do you think it works? What have you tried that didn't work? Have you decided not to do it? Why?
