Newsletter - July 2017
This month we look at why it's important to focus on habits rather than goals, Scott Wlaschin's F# for C# programmers talk from NDC Oslo and why we may need to rethink Tuckman's Theory of Group Development.

Our Opinion on ... DevOps and Software Craftsmanship
When I joined Codurance, I didn't expect that my career and mindset would end up changing so much. Whilst I'd already read about Software Craftsmanship and Agile before hand, above all, I'd always felt that I was just a coder. I would focus on creating software. All of the elements surrounding the code were therefore beyond my knowledge and interest.
This mindset changed when I joined a project that required my team to build the infrastructure for an application created by other teams. As a software developer, I discovered a whole new world which had not been visible to me before.
Since then, I've learned how to build infrastructure on AWS. I've had a chance to use many different tools such as Docker, Ansible, and Packer. But learning all of these new tools and technologies was not the biggest challenge. The biggest challenge was how to combine the low-level knowledge with actual business value, and how to organise our teams accordingly.
I soon realised that this should always be the main concern for a software engineer with a DevOps mindset. For me, it was where the principles of the DevOps movement and the declarations of the Software Craftsmanship Manifesto came together.
When trying to introduce DevOps into our organisations, we have to think about interactions between the business, software developers, and system administrators. We have to understand how we can incorporate our business experts into our daily jobs and how to focus on the business value that we are providing. DevOps teams must ensure that our software provides the proper feedback which allows us to improve and respond to changes.

You may be familiar with Tuckman's Theory of Group Development, and how teams move through the phases of Forming, Storming and Norming, before reaching their most productive phase of Performing. Doc Norton looks at the reasons why we need look beyond this theory, including how Storming may be a continual occurrence.
