Team Topologies: Organizing Business and Technology Teams for Fast Flow

by Matthew Skelton

Domains are not static and neither is the team’s cognitive capacity. But the reasoning around relative domain complexity can help shape teams’ responsibilities and boundaries. When in doubt about the complexity of a domain, always prioritize how the responsible team feels about it. Downplaying the complexity (e.g., “There are plenty of tools for continuous delivery—it’s not difficult.”) in order to “fit in” more domains with a single team will only lead to failure. To get started, identify distinct domains that each team has to deal with, and classify these domains into simple (most of the work has a clear path of action), complicated (changes need to be analyzed and might require a few iterations on the solution to get it right), or complex (solutions require a lot of experimentation and discovery). You should finetune the resulting classification by comparing pairs of domains across teams: How does domain A stack against domain B? Do they have similar complexity or is one clearly more complex than the other? Does the current domain classification reflect that?
