Maneuvering the SRE implementation
Just as in warfare, maneuvering is a critical skill in SRE. The landscape of modern business is dominated by the digital realm, and Site Reliability Engineering (SRE) has emerged as a pivotal strategy for ensuring the reliability and efficiency of digital services. However, the path to implementing and maturing SRE practices is fraught with challenges, myths, and misconceptions. Drawing parallels with Sun Tzu's "Maneuvering" and Bruce Tuckman's model of team development, this essay will explore the journey of both small and large companies in the SRE domain.
Beginning Movements: Forming Stage
For both small and large companies, the initial step is to understand the essence of SRE. At its core, SRE is about balancing the rate of change with system stability. However, a common myth is that SRE is only suitable for large organizations with vast resources. In truth, even startups can benefit from adopting SRE principles early on, ensuring a foundation of reliability as they scale.
Facing the Challenges: Storming Stage
As companies embark on their SRE journey, they often encounter resistance. For larger companies, the challenge might be the inertia of existing processes. For smaller ones, resource constraints can be a hurdle. Another prevalent myth is that SRE is just about hiring a team of engineers to manage operations. In reality, SRE is a cultural shift, emphasizing shared responsibility for reliability between product and engineering teams.
Adapting and Aligning: Norming Stage
Once the initial challenges are recognized, companies must adapt their strategies. This involves setting clear Service Level Objectives (SLOs) and understanding the tradeoffs between reliability and speed. Large companies might focus on breaking down silos and fostering collaboration, while smaller companies might prioritize automating manual processes to free up resources.
Mastery and Growth: Performing Stage

As companies grapple with the shift towards a culture of reliability, this stage is pivotal in shaping the trajectory of their SRE journey.
Conflict of Cultures and Practices: One of the primary challenges faced during the storming stage is the clash between traditional IT operations and the SRE approach. Traditional IT often focuses on maintaining the status quo, with a heavy emphasis on risk aversion. In contrast, SRE promotes rapid change while maintaining high reliability. This dichotomy can lead to tensions between teams, as they struggle to reconcile their differing perspectives.
Resource Allocation: Especially for smaller companies or those new to SRE, there's often a misconception that SRE requires significant resource allocation, both in terms of personnel and infrastructure. While SRE does necessitate investment, the storming stage often sees debates about how much is truly needed. Companies might grapple with questions like, "Do we hire dedicated SREs or train existing staff?" or "How much should we invest in monitoring and incident management tools?"
Defining Boundaries: A common challenge during this stage is delineating the roles and responsibilities of SREs versus traditional developers and operations teams. Without clear boundaries, there's potential for overlap, redundancy, and confusion. This can lead to situations where accountability is unclear, and incidents either fall through the cracks or too many teams jump in, leading to chaos.
Confronting Myths: The storming stage is rife with myths and misconceptions about SRE. Some believe it's just a rebranding of operations, while others might think it's solely about tooling. Debunking these myths is crucial, as they can hinder the true adoption of SRE principles.
Setting Realistic Expectations: As companies embark on their SRE journey, there's often enthusiasm and high expectations. However, during the storming phase, it becomes evident that SRE is not a silver bullet. There will still be incidents, and not all problems will be solved overnight. Managing these expectations and understanding that SRE is a continuous journey of improvement is vital.
Feedback Loops: A significant challenge during this stage is establishing effective feedback loops. With the introduction of new practices and tools, there's a need for continuous feedback to iterate and improve. However, in the face of resistance or skepticism, these feedback loops can be ignored or underutilized.
The storming stage of SRE maturity, while challenging, is a necessary phase for growth. It's a period of introspection, debate, and sometimes conflict. However, by navigating this stage effectively, companies lay a robust foundation for their SRE practices, ensuring that they're well positioned to reap the benefits in the subsequent stages of their journey.
