Check out Don Highsmith's Cutter article on self-organizing, suggesting that the term has lost its value to the agile community, and Tobias Mayer's response. I lean towards believing the phrase still carries useful meaning which is significantly different from 'anarchy'. So what if some people do co-opt the self-organizing label as a cover for their anarchic non-agile approach? That ought not to invalidate the term. If we allow it to, then wow, that's giving a handful of anarchists a lot of power over what the rest of us call things, isn't it? Let's just call them to account for not really being agile, and keep working to publicize how real agile teams do their work.
