What I particularly like about TOGAF is it's admirably common sense approach. Now, you may not say that when you look at a picture like this first off but it does hold true. Unlike some of the other methodologies I've trained in (Prince 2, ITIL, etc...) it doesn't proscribe a rigid methodology, but emphasises the need for flexibility in encountering real-life conditions.. And in training, I found it very true to the actual approaches I was already employing and the situations I'd actually encountered.
