In this talk, Nigel peddles devops, continuous delivery and other habit-forming approaches that elevate teams towards Agile heaven. Devops is all the rage, but what is it and how does it relate to Agile? Can you do devops without being devops? Is devops even a word? Bio: Nigel Charman is Service Lead for Continuous Delivery and DevOps at Assurity Consulting. He helps clients deliver software faster, better and cheaper, often through adoption of continuous delivery and devops culture and practices. He loves changing the way that people think about software delivery and seeing them create innovative approaches and techniques. With a background in software development, Nigel first introduced continuous integration to his team in 2003. Since joining Assurity in 2005, Nigel has grown Assurity's continuous testing and delivery services. He has presented continuous testing and delivery approaches and case studies at CITCON, Iqnite and GOVIS conferences.

It’s not just Dev + Ops

Why a new movement?
•We forgot to invite Ops to our Agile party
•Agile 2008, Patrick Debois and Andrew Shafer set up a BOF
for “Agile Infrastructure”. No-one came.

At Velocity 09, John Allspaw and Paul Hammond presented
“10+ Deploys Per Day : Dev & Ops Cooperation at Flickr”
This led to Patrick Debois setting up a conference called
DevOpsDays

Defining devops - Patrick Debois
“In my mental model of devops
there are 4 'key' areas:”
“devops : collaboration, optimization across the whole organisation
devops 'lite' : when people zoom in on 'just' dev and ops collaboration”
