When using OOAD artifacts to organize and assign team responsibilities on a project, it is BEST to:
a) evenly distribute use cases among team members and have them work as independently as possible in order to minimize code dependencies
b) designate one team for implementing interaction diagrams related to the "common code path" and another team for implementing interaction diagrams related to "code path variations" (for example ? conditional or error paths)
c) divide teams according to package diagram dependencies and utilize use cases to schedule the work for the individual team members
d) divide teams according to the layers in the software architecture and have them work as independently as possible in order to minimize dependencies between the layers}

Referring to these partial requirements, which of the following is true?

b) Some of the verbs in the requirements become methods of the nouns they reference. E.g., a FinancialInstitution class would have a getFinancialInformationFor( aCustomer ) method.
c) Some of the verbs in the requirements become methods of the concept taking the action. E.g., a LoanOfficer class would have a getFinancialInformationFor( aCustomer ) method.
d) Some of the verb phrases in the requirements become overriding methods of the related superclass, due to the specialization of the action.

Software entropy is a phenomenon wherein programs begin with well designed state, but as new functionalities are added, they lose their structure. Refactoring of classes is done to avoid software entropy. What are good practices to follow during refactoring?
a) Renaming a method and moving a field from one class to another should be done in small steps,
testing changes as required.
b) Break down classes that are heavily loaded with responsibilities into smaller classes and distribute the responsibilities among them effectively.
c) Consolidate similar methods from different classes in the same type hierarchy into a common super class wherever possible.
d) Add functionality and refactor simultaneously in order to obtain an efficient and effective design.
