On-Call Culture and the Human Aspect: Prioritising Well-being in the Realm of Reliability



-Site Reliability Engineering is synonymous with ensuring system reliability, but the human factor is an often-underestimated part of this discipline. Ensuring a healthy on-call culture is as critical as any technical solution. The well-being of the engineers is an important factor.

-Firstly, a healthy on-call rotation is about more than just managing and responding to incidents. It's about the entire ecosystem that supports this practice. This involves reducing pain points, offering mentorship, rapid iteration, and ensuring that engineers have the right tools and processes. One ceavat is, that engineers should be willing to learn. Especially in on-call rotation mixing SREs with other engineers (for example Software Engineers or QA Engineers), it's difficult to motivate everyone to engage. QA Engineers want to test the software, Software Engineers want to implement new features; they don't want to troubleshoot and debug production incidents. It can be depressing for the mentoring SRE.

-Furthermore, the metrics that measure the success of an on-call experience are only sometimes straightforward. While one might assume that fewer pages translate to better on-call expertise (which is true to a certain degree, as who wants to receive a page out of office hours?), it's not always the volume of pages that matters most. Trust, ownership, accountability, and effective communication play the important roles.

Trust, ownership, accountability, and effective communication play the important roles.

An important part is giving feedback about the on-call experience to ensure continuous learning. If alerts are mostly noise, they should be tuned or even eliminated. If alerts are actionable, can recurring tasks be automated? If there are knowledge gaps, is the documentation not good enough? Continuous retrospection ensures that not only do systems evolve, but the experience for the on-call engineers becomes progressively better.

An always-on, always-alert culture can lead to burnout. Engineers should be encouraged to recognise their limits, take breaks, and seek support when needed. This isn't just about individual health; a burnt-out engineer can have cascading effects on the entire team and the systems they manage. A successful on-call culture ensures that while systems are kept running, the engineers are kept happy, healthy, and supported. The more experienced engineers should take time to mentor the junior engineers, but the junior engineers should also be fully engaged, try to investigate and learn new things by themselves.

-For the junior engineer, it's too easy to fall back and ask the experts in the team every time an issue arises. This seems reasonable, but serving recipes for solving production issues on a silver tablet will only scale in the short run, as there are infinite scenarios of how production systems can break. So every engineer should learn to debug, troubleshoot and resolve production incidents independently. The experts will still be there for guidance and step in when the junior is stuck after trying, but the experts should also learn to step down so that lesser experienced engineers can step up and learn. But mistakes can always happen here; that's why having a blameless on-call culture is essential.

-A blameless on-call culture is a must for fostering a safe and collaborative environment where engineers can effectively respond to incidents without fear of retribution. This approach acknowledges that mistakes are a natural part of the learning and innovation process. When individuals are assured they won't be punished for errors, they're more likely to openly discuss mistakes, allowing the entire team to learn and grow from each incident. Furthermore, a blameless culture promotes psychological safety, enhances job satisfaction, reduces burnout, and ensures that talent remains committed and engaged.

Site Reliability Engineering has established itself as more than just a set of best practices or methodologies. Instead, it stands as a beacon of operational excellence, which guides engineering teams through the turbulent waters of modern software development and system management.

-In the universe of software production, two fundamental forces are often at odds: The drive for rapid feature release (velocity) and the need for system reliability. Traditionally, the faster teams moved, the more risk was introduced into systems. SRE offers a approach to mitigate these conflicting drives through concepts like error budgets and SLIs/SLOs. These mechanisms provide a tangible metric, allowing teams to quantify how much they can push changes while ensuring they don't compromise system health. Thus, the error budget becomes a balancing act, where teams weigh the trade-offs between innovation and reliability.

These mechanisms offer a tangible metric, allowing teams to quantify how much they can push changes while ensuring they don't compromise system health. Thus, the error budget becomes a balancing act, where teams weigh the trade-offs between innovation and reliability.

-A quintessential component of this balance is the dichotomy between operations and coding. According to SRE principles, an engineer should ideally spend an equal amount of time on operations work and coding - 50% on each. This isn't just a random metric; it's a reflection of the value SRE places on both maintaining operational excellence and progressing forward with innovations. This balance ensures that while SREs are solving today's problems, they are also preparing for tomorrow's challenges.

This balance ensures that while SREs are solving today's problems, they are also preparing for tomorrow's challenges.

However, not all operational tasks are equal. SRE differentiates between "ops work" and "toil". While ops work is integral to system maintenance and can provide value, toil represents repetitive, mundane tasks which offer little value in the long run. Recognising and minimising toil is crucial. A culture that allows engineers to drown in toil stifles innovation and growth. Hence, an organisation's approach to toil indicates its operational health and commitment to balance.

-A cornerstone of achieving operational balance lies in the tools and processes SREs use. Effective monitoring, observability tools, and ensuring that tools can handle high cardinality data are foundational. These aren't just technical requisites but reflective of an organisational culture prioritising proactive problem-solving. By having systems that effectively flag potential issues before they escalate, SREs can maintain the delicate balance between system stability and forward momentum.

Moreover, operational balance isn't just a technological or process challenge; it's a human one. The health of on-call engineers is as crucial as the health of the services they manage. On-call postmortems, continuous feedback loops, and recognising gaps (be it tooling, operational expertise, or resources) ensure that the human elements of operations are noticed.

-In conclusion, operational balance in SRE is not a static thing but an ongoing journey. It requires organisations to constantly evaluate their practices, tools, and, most importantly, their culture. By achieving this balance, organisations can ensure that they have time for innovation while maintaining the robustness and reliability of their systems, resulting in sustainable long-term success.

-That all sounds very romantic. The truth is, it is brutal to archive the perfect balance. No system will ever be perfect. But at least we should aim for it!

SRE and Organizational Culture: Navigating the Nexus



-At the heart of SRE lies the proactive mindset of "prevention over cure". Traditional IT models focused predominantly on reactive solutions, but SRE mandates a shift towards foresight. By adopting Service Level Indicators (SLIs) and Service Level Objectives (SLOs), teams are equipped with clear metrics and goals that guide them toward ensuring reliability and user satisfaction. However, these aren't mere numbers. They reflect an organisational culture prioritising user experience and constant system alignment with user needs.

-Another defining SRE concept is the "error budget". This ingenious framework accepts that no system is flawless. Failures are inevitable. However, instead of being punitive, the culture here is to accept, learn, and iterate. By providing teams with a "budget" for errors, organisations foster an environment where innovation is encouraged, and failures are viewed as learning opportunities.

-But SRE isn't just about technology and metrics; it's deeply human. It challenges the "hero culture" that plagues many IT teams. While individual heroics might occasionally save the day, a sustainable model requires collective expertise. An SRE culture recognises that heroes achieve their best within teams, negating the need for a hero-centric environment. This philosophy promotes a balanced on-call experience, emphasising the importance of trust, ownership, effective communication, and collaboration as cornerstones of team success. I personally have fallen into the hero trap, and I know it is unsustainable to be the only go-to person for every problem.

-Organisations might face a significant challenge when adopting SRE. It is convincing various teams and leadership of its merits. Some might feel SRE principles counter their goals. They might prioritise feature rollouts over reliability or view SRE practices as cumbersome. Hence, fostering an SRE culture often demands patient explanations and showcasing tangible benefits, such as increased release velocity and improved user experience.

It calls for cultural transformation from the on-call engineers to the boardroom.

It paves the way for a shift in organisational culture that values proactive prevention, continuous learning, collaboration, and transparent communication. The successful melding of SRE and corporate culture promises not just reliable systems but also a robust, resilient, and progressive work environment.
