Synthesis is harder than analysis

Drawing an analogy from calculus, this post argues that synthesis (integrating knowledge across a system) is fundamentally harder than analysis (breaking problems into local, isolated parts). Differentiation is easy because it is a local operation; integration is hard because it requires global knowledge. The same principle applies to SRE work: understanding how individual components interact across a system is a synthesis problem, and it is inherently more difficult than understanding each component in isolation. The author argues that the industry undervalues building synthesis expertise in SREs, and advocates for developing better methods for learning the operational details of complex systems.
