. One part of the CRC (class–responsibility–collaboration) card technique requires team members to act out scenarios by playing the parts of objects represented by the CRC cards. What are the advantages and disadvantages of doing this? If you were involved in a team project, explain why you would or would not act out the scenarios. Do you think that the CRC card technique and acting out scenarios would be helpful when team members were geographically dispersed (i.e., not all in the same office)? . 2.an example analysis model for an ATM was produced. Critique the final version of the model. Any aspect of the model is open for comment. One consideration in particular is the inheritance hierarchies: Do you agree that they could be useful; is there any other inheritance you think should be modelled? A rationale was given for the Account class hierarchy, but details of what the sub-classes do were purposely left a little vague. If you think this hierarchy is useful, elaborate on what the sub-classes could do to specialise the Account class. If you do not think the hierarchy is useful, explain why not. Also consider the classes and their responsibilities: Does the model seem to make sense, or do you think something is missing because you cannot see how parts of the system would work based on this model?
