Run a deterministic Monte Carlo simulation of flow through the portfolio PDLC — baseline from the workspace's own flow history, plus what-if scenarios (WIP limit changes, arrival-rate shaping, dependency-tax reduction from platform extraction or team reorganization). Use as the Discovery move for improvement bets before anyone changes policies or reorganizes teams, or to set Service Level Expectations. Advanced member of the portfolio-pdlc family; produces confidence-labeled forecasts, never point predictions.
