The 'in industry' equivalent is 'on-the-job-training'. Employers love the idea that a software professional instead of taking a few days to acquire a new skill or technology, can just do it by using said skill on a client's project without preparation and learn as you go along.

This always fails as there is never time budgeted for this in the schedule, so the software professional is not just facing the traditional underestimated deadline, but is now faced so doing with partially unknown tools and under intense pressure to just cut every corner and rush the first ting that doesn't blow up completely. Next project, the 'new tech' is now considered 'known' and so the kludges become practice and decent learning never occurs.
