Our first model, (left),
which represents the current situation,
consists of a client producing,
for example, requests for a loan at a bank. The requests are initially handled by a clerk whose task is to send requests for amounts greater than $10,000 to the boss. The boss, whose task is to approve or deny the loan, sends the result back to the clerk for processing. If the amount is less than $10,000, the clerk has authority to process the request himself.
Redesign alternative:
In our second model, (right),
which is the result of
a redesign effort, requests are handled by a clerk
who enters the data into a computer. The computer now makes the decision as to whether the loan is improved -- for loans of value
less than and greater than 10,000. The clerk then passes the results on to another clerk for the task of dispatching loans.
