DevOps messes with your head - reprised

Last year I wrote about how DevOps messes with your head, or as we say down here, it does yer head in.

In the interim I have been adding more examples to the presentation which I shared.

DevOps Configuration versus ITSM CMDB

Devops configuration tools means something quite different to ITIL configuration tools (cmdb).

This blog first gathered its following by saying that cmdb is an unhealthy aspiration for nearly all organisations.

DevOps isn't a tool to be applied selectively

Several times lately I've come across the idea that DevOps is a localised technique which can be used on one team or application, and not another. This isn't true. DevOps is a cultural transformation,a journey not a state or a tool. The primary goal of that transformation is to increase collaboration towards a common goal, to break down silos. A bi-modal model achieves the opposite.

DevOps Enterprise Summit: humane IT

Returning from DevOps Enterprise Summit in London, I'm reflecting on the experience.

Kill the CAB

ImageRequiring permission from a Change Advisory Board after a change is complete is absurd. A system has to be broken to need any discussion by that stage. Fix the system and kill the CAB. Its possible.

Change goes away

Welcome to the new world of IT: systems thinking.

why DevOps transformations succeed where ITSM so often doesn't

I've consulted on many ITSM initiatives and it always seemd a struggle to effect improvement: all stick and no carrot; dragging horses to the river with no interest in drinking. My DevOps consulting these days is a different experience - of happy horses following willingly and drinking their fill. The difference between ITIL and DevOps is that DevOps works.

Optimising control constraints

Here are some notes I wrote for a client on how to optimise the constraints created by controls on the Require to Deploy to Run value stream.
