Maximize cohesion, minimize coupling

Andrew Harmel-Law is our guest of this week, and he will share his experiences over the heuristic “Maximize cohesion, minimize coupling” from the Xebia Essentials repository (https://essentials.xebia.com/maximize-cohesion-minimize-coupling/). We start discussing the original scope of the heuristic, the software code, but quickly expand to his experiences with cohesion and coupling at the organisation level.

We discuss how the communication pathways can enable and harm an organisation, and how the knowledge silos can be broken. Andrew shares his architecture practices, namely how to move between the Domain-Driven Design strategic patterns to the tactical patterns, crossing the different organisation layers effectively.
