Last week was DevOpsDays London and it was quite an event. Knowledge sharing, open discussions ranging from leadership to technical, networking, seeing what vendors were bringing to the market and listening to the sage voices of several of the leaders of this collaborative technology movement.
My key take-aways:
- We all have the same problems!
- It used to be seen that DevOps was for small technology companies or for those just wanting to use it to enhance their digital capabilities. Now everyone wants to do and the concept of bi-modal is being swept away (thankfully, as we all recognise that IT has always had services that run on different agendas and we need to manage these variable cadences).
- DevOps drives business process change
- But to do this well and have a flow of work being delivered with feedback as fast as possible on issues or enhancements then business processes have to change. No longer is it acceptable to provide us with an annual budget while being asked to deliver in 2 week sprints.
- IT Service Management is alive and well in DevOps – thank you!
- When Gene Kim said he was from an ITSM background and that without ITSM practices DevOps could not improve, well, I am surprised Twitter did not crash. DevOps relies on other technology movements like Agile and lean but it is based on ITSM. That blending of practices is what makes DevOps the best movement thus far to manage technology for the benefit of the customer.
- Lean in IT – really?
- Yes! Joanne Molesky, co-author of Lean Enterprise, spoke elegantly on how lean with its customer and improvement focus enhanced the practices of leading technology. Metrics that matter, visualisation based on monitoring, testing everything including the process of requirements gathering and definition can all learn from lean techniques.
- Metrics: what are they?
- They are not simply measuring velocity. They are looking at Cost of Delay, MTTR (Respond to Return to Customer), customer satisfaction, quality and cost is an outcome not a goal. Using lean catch-ball to align teams and vendors can drive the delivery of technology features and enhancements.
- DevOps can help relieve stress
- Ah yes I remember the ole days! Pager on, phone on, Bat-suit ready: ok where is the issue? This really is not what we want to be doing. We want to being building Services as Code. We want to be involved in looking at how technology can remove an obstacle or achieve a goal for the business. DevOps stresses the Culture and Sharing of knowledge aspects of management, not just the automation.
- Age is not an issue!
- Yes I am older than most of the delegates and yes I was teasingly called Dad. But I was also asked how things have changed, what can we learn from the past, what would I do going forward, how do I engage with C-level or middle management and other non-technical questions. Don't get me wrong, there was also plenty of discussion and a live demonstration on firing up an environment with a few lines of code but the emphasis on the people side was refreshing.
DevOps in London is back some say. Well it never left. Look for http://www.meetup.com/DevOps-Exchange-London/. Webinars and courses like those offered by Ranger4 (see our website) help you learn more about DevOps.
Finally a warm thank you to Gene Kim and Joanne Molesky for spending time with me and sharing their thoughts on lean and DevOps.
Will we see you at DevOps Enterprise Summit London which is set to be the biggest event of the year? Let us know!
