> The numbers at this size appear insignificant. How would one (say an engineer) convince "the management" that the extra 0.0475% of availability is worth the investment/expense? In businesses where physical goods are sold to customers, "the management" is generally very motivated to avoid stock-out situations in which sales are lost due to lack of inventory (even if it's only a very small percentage.) The reason for this is because they are concerned about the potential loss of customer goodwill. It seems that the same applies in this situation.
