What works and what doesn't work in software development? For the first 10 years or so of my career, we followed a strict waterfall development model. Then in 2008 we started switching to an agile development model. In 2011 we added DevOps principles and practices. Our product team has also become increasingly global. This blog is about our successes and failures, and what we've learned along the way.

DevOps Days Open Space: How Can Ops Teams Give Feedback to Dev Teams?

This was another interesting Open Space that I participated in: How Can Ops Teams Give Feedback to Dev Teams?

Chaos Monkey can teach developers where things might break.  You need to couple that with some sort of monitoring tools so you can find bugs of the performance/throughput/overload type as well.

People in ops would like developers to program more defensively.  Developers are not generally taught how to do this.  It's also not usually part of their culture. 

One great way to tech developers is by writing tests that fail.  Developers are great at fixing tests that fail.

Another best practice is to embed developers in operations and vice versa.  Some companies have done this with teams of people for months or years at at time.  Others rotate people between the teams for one day every couple of weeks.  Set it up like an apprenticeship, where people can start out with a mentor and gradually become responsible for their own things.

Operations people can review code!

Developers can have pagers!

Product managers need to care about operational constraints and include those in the requirements that they put on the development teams.

You need to get everyone in the company to think about business value and happy customers.  Constantly.

You need to get everyone in the company to watch dashboards.  Give each person a few graphs to watch on a dashboard.
