Decisions before models
Data and intelligence projects rarely fail because charts are ugly. They fail because one metric has three algorithms in three teams. Whether sales include returns, order or receipt, tax-in or tax-out—half an hour of definition fights, then the board is meaningless. We start with a metric dictionary: definition, source table, refresh, owner. Warehouse layers and sync jobs serve metrics; we do not pile tables and then ask “what can we see.” An unowned metric is disbelieved in three months.
