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.

My one big takeaway is that IT is finally a people industry. The talk is of happiness, safety, empowerment. Hippies like me feel at home again. Gene's passion is "humane IT" and it shows.

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

What does IT operational production change management look like in a highly DevOps-driven organisation? It doesn't. It vanishes.

I have learnt better now.

DevOps represents the emergence of systems thinking in IT

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.

Two questions to ask

Here are two questions you can ask yourself, or you can ask any person or team, to challenge them to change the way they work:

  • Can you show how your work will be better in a year?
    We want to know whether there is any improvement programme, or any bandwidth for improvements, or even any culture based on improvement.
  • Can you keep working in this way indefinitely?

DevOps has three parents: Lean, Agile, and ITSM

DevOps synthesises three bodies of knowledge: Lean, Agile, and ITSM.
