Your Team Already Has Patterns. They Just Don't Know It.
When I started a new role, one of the first things I did was try to understand how data moved through the system. Not the dashboards, not the data models — the pipes. Where did things come from? How did they get in? What happened to them along the way?
There were somewhere between twenty and thirty source systems feeding the platform. Not a massive number, but enough to tell a story when you looked at the ingestion layer all at once. What I found was that all the pipelines had originated from two base templates. A sensible starting point. The kind of thing a small team puts in place early to stop complete chaos.
