More and more teams are turning to DevOps as a way of working together to improve the efficiency and quality of software delivery and start adding more value to the business. But without having someone on the team with experience of putting it into practice, it's sometimes difficult to know how to get started. Redgate Software invited Steve Thair, CTO at the DevOpsGuys, to deliver a one-hour training session on 'How to get started with DevOps'. Steve gave practical tips on how you can start implementing DevOps in your own organization. The recording can be found here - https://youtu.be/ZioF58drwcA For more information about services from the DevOpsGuys visit www.devopsguys.com To find out about extending DevOps practices to the database visit www.red-gate.com/solutions

- Remember those two words for later…
- Stop talking about Business versus IT like you’re two separate countries. Our colleagues in Sales Our Colleagues in Marketing Or better – Sally our product owner from Finance, or Dave our product owner from Merchandising
- Feedback loops game
- Work in cross-functional teams Discuss how to improve the process at every retrospective
- Write a post-it Describe something you consider to be wasteful Add it to the snake at the end of the chain Discuss in the retrospective
- That is producing 2000 cars a day (so more than 1 a minute) (1440 minutes a day)
- Why would Toyota do something so disruptive as stopping the production line thousands of times per day? And when the supervisor comes over the first thing he says to the worker is… “Thank You” – thank you for your commitment to quality and thank you for the opportunity to learn how to improve! “Is the only way we can build 2,000 vehicles per day – that’s one every 55 seconds” At a level of quality – otherwise we’re producing 2000 sh*t vehicles that need re-work!
- Is this a good metric? Metrics without context need to be treated with care.
- Not having a goal is like driving blind
- Key concept is to shorten the cycle times as much as possible.
- It’s very common to see “person-years” of effort in a release. Which would you rather debug – a small, single feature change or person-years worth a stuff dumped on your at once (MTTR reduction is the goal too).
- Pathological organisations are characterized by large amounts of fear and threat. People often hoard information or withhold it for political reasons, or distort it to make themselves look better. Bureaucratic organisations protect departments. Those in the department want to maintain their “turf,” insist on their own rules, and generally do things by the book — their book. Generative organisations focus on the mission. How do we accomplish our goal? Everything is subordinated to good performance, to doing what we are supposed to do
- Amazon model is massively inefficient
