As the subtitle says, this talk tries to embed DevOps in a broader context. Therefore first briefly is sketched, how the state of IT is perceived by many people in IT. Additionally, DevOps is briefly defined by explaining the three ways as they were described in the book "The Phoenix Project".
After this short introduction the claim of the title is picked up: "Why is DevOps not enough?". In order to explain this claim, the history of economic markets and of IT are briefly explained. The bottomline is that almost all markets supported by IT have drastically changed in the years since IT became relevant for companies. Additionally, IT itself has changed dramatically in this period of time. Therefore, most of the common knowledge and best practices, we stick to in IT became counter-productive meanwhile because they solve a completely different problem, i.e., the problems of the times when the markets and IT itself were totally different.
The conclusion from the short examination of history is that we basically have to re-think IT as a whole, which is discussed briefly in the next section of the talk. This section first has a look at the new drivers that inflict change on IT. Then it derives the new goals of IT and shows some of the building blocks.
Having this new idea of IT at hand, the role of DevOps in it is finally considered. Starting with DevOps and its continuous pursuit of shortening cycle times in order to optimize outcome, DevOps can be used to drive the change of IT. This is exemplarily shown by starting with DevOps and then see, which question arise from that and what solutions it leads to. In the end of the example, many of the building blocks of the new IT are in place - just by starting with DevOps and continuously improving.
This is a very dense talk covering a lot of ground in order to lead to the final observation that DevOps can (and should) be used to drive the required change of IT and many detail have been left out. Also the voice track is missing of course, but I still hope that it provides you with some useful information.
