This is an interesting article although I’m not quite convinced modifying ITIL is the correct place to start the debate, I think I prefer the concept of adding useful parts of ITIL to other methodologies, to suit the business requirements.
Of particular interest is the consideration of how, or if to implement ITIL in organisations where it is not in place, seems this could be the opportunity to cherry-pick some ITIL framework ideas and mould them into supporting and complementing Agile to organise and improve the reactive capabilities of IT Ops.
However you slice it, smoothing the flow through IT is the endgame.
