1) Why should accountants be concerned with the development of bills of material ?

2) Think about the UML class diagram for - the sales collection process and - the purchase and payment process.

If you were asked to (you don't need to) prepare an integrated model that shows those two processes as well as the conversion process Where would the models intersect/ integrate? Why ? What elements are unique to each process?

3) Compare the generic UML class diagram for the conversion process shown in image 1 with a generic sales and collection diagram image 2 (attached both of them). Describe the similarities and differences and explain the reasons for those similarities and differences.
