One postponed delivery date for a single item holds up the construction crew for fourteen days.
The order is in the ERP, the supplier's order confirmation arrives in purchasing as an email attachment, and the installation date sits in the construction schedule. Nobody checks these three sources against each other every day. The delay only comes to light when dispatch requests the material for the installation week and it is not in the warehouse.

On the day the order confirmation arrives, the delay still means replanning rather than waiting, and that is exactly where the 40% fewer delivery delays come from.
The 40% reduction in delivery delays is this agent's headline figure. The order items, changed dates and fourteen waiting days describe a typical course of events in a grid expansion project; they are not measured values.
