On one client mission, the technical foundation was honestly solid. The catalog was connected, lineage existed, governance workflows were running and teams could already access a lot of data. Yet every governance discussion turned into the same problem: ↳ Who decides? ↳ Who owns customer profitability? ↳ Who validates KPI definitions? ↳ Who arbitrates when two teams calculate the same metric differently? 𝗧𝗵𝗲 𝗶𝘀𝘀𝘂𝗲 𝘄𝗮𝘀 𝗻𝗼𝘁 𝘁𝗵𝗲 𝗽𝗹𝗮𝘁𝗳𝗼𝗿𝗺. 𝗜𝘁 𝘄𝗮𝘀 𝘁𝗵𝗲 𝗮𝗯𝘀𝗲𝗻𝗰𝗲 𝗼𝗳 𝗱𝗼𝗺𝗮𝗶𝗻 𝗮𝗰𝗰𝗼𝘂𝗻𝘁𝗮𝗯𝗶𝗹𝗶𝘁𝘆. A data domain is not just a way to group datasets by topic. It creates decision boundaries around business capabilities like customer, finance, HR or supply chain. That boundary matters because governance only works when ownership becomes operational. Without clear domains, the platform becomes a very expensive shared storage layer where every important decision still needs meetings, negotiations and escalations. Technology scales fast. Unclear ownership scales chaos even faster. ——— 📌 Save it for later. 👋 Follow Mathieu Le Guével to fix Data Governance.
