Five questions that expose weak IBP maturity

Alain Matar proposes assessing IBP maturity through five questions concerning ownership of the demand number, reactions to forecast error, decisions from management reviews, the realism of supply constraints and evidence of improvement from the previous cycle.

These questions can provide a useful rapid diagnostic, but they should not replace a full maturity assessment when investment or organizational redesign depends on the result. Each answer should be supported by meeting decisions, ownership records, forecast metrics and closed-loop improvement evidence.
