The Predictive Feedback Cycle

The AI flywheel. Data -> Prediction -> Better Use -> More Data

Company Training: Out to go up

New Employee Hired -> Great Internal Training -> New Skills -> External Offers Come In -> Employees Leave

New Employee -> No Training or Training on Obsolete Tech (COBOL) -> Employee Stays and Teaches COBOL

Data Standardization Cycles

Ten Groups/Ten Standards -> Central Warehouse Fail -> Data Marts Too Expensive -> Few Insights - Lower Marketplace

Ten Groups -> Great Canonical Model -> Shared EKG -> Deep Insights -> More Marketshare
