At Blameless, we drink our own champagne, and aim to adopt a mindset of continuous learning to foster resilience. We believe that the adoption of SRE practices is one of the best ways to get there. Like most organizations, our early efforts to implement SRE were imperfect. However, through hard work, teamwork, and investing in what we believe is the most important feature (reliability), we have made significant changes to how we do SRE. And we’re getting better at it every day.

How well positioned is your team to ship reliable software? What are the different roles in engineering that impact reliability, and how do you optimize the ratio of software engineers to SREs to DevOps within teams? These questions can be hard to answer in a quantifiable way, but projecting different scenarios using systems thinking can help. Will Larson’s blog post Modeling Reliability does just that, and serves as inspiration for this article.

For many SREs, networking prompts a similar response as going to the dentist. You know you should do it, but you don’t really want to. But networking is much less like a root canal and more like a regular teeth cleaning; you may not want to go, but once you’re there, it’s not so bad. In fact, you may walk away feeling good knowing that you’ve done something that helps future you.

One of the most important steps in an incident’s lifecycle is the postmortem. It provides an essential time to reflect on what happened, what could have been done better, and how to build more resilience into a system. But we consistently hear from engineers that incredible toil is typically involved in coordinating stakeholders to write good postmortems.

It’s a new year, so what will 2020 have in store for SRE? Here’s our two cents: SRE adoption will only continue to grow. However, the practice and culture shift, rather than the role, will take priority in 2020. More people (not just SREs) will have a reliability mindset, shifting reliability left through the software lifecycle. SLIs, SLOs, and error budget policies will become common practice to make this shift actionable.

Service Level Objectives, or SLOs, are an internal goal for the essential metrics of a service, such as uptime or response speed. We’re probably familiar with this definition, but what is the value of setting these goals? We’ll take a look at SLOs as both a powerful safety net and a tool to inform the allocation of engineering resources, while also considering the cultural learnings of SLO adoption.

Reading about postmortem best practices can sometimes be quite different from seeing them in action. Postmortems are like snowflakes; no two will ever look the same. There isn’t a definitive template for success that will work in every situation, but there are some practices and procedures when writing postmortems that can help. Here are five practices that can boost the effectiveness of your postmortems, with examples of postmortems or procedures that demonstrate these methods.

We’re probably all familiar with Dickens’ story of Scrooge and the Three Ghosts of Christmas, written all the way back in 1843. What we may not know is that ghosts providing visions and teaching lessons is still common practice today! Let’s look into the carol of an ambitious, but unreliable, tech CEO.

My name is Simone Salman, and I’ve been working as a software engineer at Blameless since May 2019. In the spirit of thanks as we’re approaching the holidays, I wanted to reflect on my time at Blameless thus far, and share a few things about the culture that I’m especially grateful for.
