Key Words: customer demand (variable, high, low), too many/few (products/ types, people, resources including people), schedule (variation), inventory (off, low, excessive). How to Find Root Causes of Unpredictability-Caused Defects Correlation Analysis—Because you are not looking for controllable root causes but predictors for unpredictability problems, the search can include nonplausible as well as plausible predictive factors.

You insert those levels in a model. You make a prediction. Then you compare your prediction to what actually happens. If the prediction and reality do not match sufficiently closely, then the root cause is the model. Unpredictability sequence: Predictors → check actual predictor levels → model → prediction → ­comparison to reality The key difference between this case and suboptimality is the second step.
