Use Case Points

Correct Answer: ECF would rise due to the lack of user familiarity, increasing the overall use case points

Environmental Complexity Factor (ECF) in use case points is directly related to the level of user familiarity with the system. If users are less familiar with the system, the environmental complexity is going to be higher, hence ECF will rise. This will subsequently lead to an increase in overall Use Case Points as complexity increases effort and time required for implementation. Therefore, the answer 'ECF would rise due to the lack of user familiarity, increasing the overall use case points' is chosen as correct As for the other answers: The statement 'ECF remains unchanged regardless of user familiarity' is false because the familiarity of users directly impacts the ECF The statement 'ECF would decrease due to the lack of user familiarity, reducing the overall use case points' is incorrect because ECF actually increases with a lack of user familiarity, not decrease The statement 'Only UUCP is impacted and not the ECF' is incorrect because both UUCP (Unadjusted Use Case Points) and ECF are essential components in the calculation of use case points.

Correct Answer: The Use Case Points would increase due to a more complex actor.

In the calculation of Use Case Points, actors' complexity is taken into account along with the complexity of use cases. The actor's complexity may depend on various factors like the amount of interaction needed, the amount of data to be exchanged, how well the actor's behavior has been defined, etc. So, if there's an actor that is known to be complex, it would result in an increase in the overall Use Case Points. This is because a more complex actor typically requires more effort to implement, and hence increases the Use Case Points, which are a measure of software project size and complexity. The answers suggesting that actor complexity doesn't influence or decrease the Use Case Points are incorrect.

Correct Answer: Assign different actors for different user roles as they interact differently with the system.

In a project set-up that includes many users interacting with the system in various ways, the correct approach to calculating Use Case Points (UCP) would be to 'Assign different actors for different user roles as they interact differently with the system.' This is because, in UCP estimation, different actors represent various types of users, each having a different interaction pattern with the system. So, having different actors for different user roles allows for a more accurate estimation of complexity and effort. The other options are inappropriate in this case: 'Assign one generic actor for all user interactions with the system.' is incorrect because it oversimplifies the various user interactions and can lead to underestimating the complexity and effort involved in the project. 'Disregard the differences and consider the user's interaction as a single use case.' is also incorrect because ignoring the differences in user interactions can lead to a misunderstanding of the system's complexity and hence a misestimation of the effort needed. Finally, 'Simplify the use cases so that all users interact with the system similarly.' is fundamentally flawed because altering the use cases to oversimplify user-system interactions will not accurately represent the project's complexity and can lead to false projections of effort and cost.
