The essence of the 333 rule:
- Whenever there is a request for a new report that requires new data source or additional data sets from existing sources, first create manual extracts, pull them into text files and create "reports" on top of these extracts
- If, and only If, after 3 weeks, the new reports are still being actively used, they then point the reports directly to the operational data sources.
- If, and only If, after 3 months, the reports are still being actively used, they then create new DW tables and populate them with the new data sets.
- If, and only If, after 3 quarters, the reports are still being actively used, they then completely productionalize the process with QA, UAT, DR and other production controls, risk management, and operational procedures.
