What good practices, if any, has the agile movement lost? [closed]

Question

I am a long time agile advocated but one of the things that bothers me about Agile is that a lot of agile practitioners, especially the younger ones, have thrown out or are missing a whole lot of good (non Scrum, non XP) practices. Alistair Cockburn's style of writing Use Cases springs to mind; orthogonal arrays (pairwise testing) is another.

I read mostly Agile related books and articles and work with mostly Agile folk ... is there anything I'm missing?

Answer 1

It might be interesting in 5-10 years time to see how maintainable these systems are when nobody wrote down why a particular decision was made and all the people involved have left.
