Using the theory of Littles' Law $($Throughput $=$ Work In

Process x Cycle Time$).$ A vehicle licensing centre receives

application documents, keys in details, checks the information

provided on the application, classifies the application

according to the type of licence required, confirms payment

and then issues and mails the licence. It is currently processing

an average of $5,000$ licences every $8-$hour day. A recent spot

check found $15,000$ applications that were $\text{'}$in progress' or

waiting to be processed. The sum of all activities that are

required to process an application is $25$ minutes. What is the

throughput efficiency of the process?.
