4. As one of Barilla's customers, what would your response to JITD be? Why? In the environment in which Barilla operated in 1990, do you believe JITD (or a similar kind of program) would be feasible? Effective? If so, which customers would you target next? How would you convince them that the JITD program was worth trying? If not, what alternatives would you suggest to combat some of the difficulties that Barilla's operating system faces?

a) 6.3 effective man x hours per day, five business days per week, 13 weeks per quarter.

b) All inter-arrival times between two consecutive loans of the same type have a coefficient of variation equal to 0.85, and the average arrival rates of the various types of loan can be obtained from the second to last row of the table in Exhibit 1.
