ING Bank is one of the largest banks in a small country (the Netherlands), with a long history as a system bank in the Dutch society. Until five years ago, ING had a traditional IT organisation. The management believed in Prince II, CMMI, ITIL, outsourcing and large programs. When that paradigm really failed to deliver value, ING experimented with Agile, then rolled out Agile and DevOps at a rather extreme scale.
