A large retailer operates a limited fleet of same-day-delivery trucks.
For years, each neighborhood delivery hub has been assigned the same number of trucks, regardless of the daily order volume in that neighborhood.
To shorten overall delivery times, senior management now plans to let neighborhood hubs trade truck assignments freely. Management argues that trading will move more trucks to the neighborhoods that rely on them most intensively, thereby reducing average delivery time across the company.
To evaluate whether the company’s plan is likely to achieve its intended result, it would be most helpful to know which of the following?
(A) Whether neighborhood hubs facing tighter shipping deadlines currently use their trucks more frequently than other neighborhoods.
The argument is not concerned with shipping deadlines but about trading truck assignments with neighborhood hubs.
