Exam CBAP topic 1 question 286 discussion

Actual exam question from IIBA's CBAP
Question #: 286
Topic #: 1
[All CBAP Questions]

A company that specialized in manufacturing vending machines for books has been in business for 10 years. As the e-book and online retailing grow, the company perceived that a change is required to respond to the new emerging market forces. However, the change should focus on reusability as much as possible to reduce expenses. After analyzing the current state with the business subject matter experts, the business analyst (BA) proposed investing in a new business line of vending machines that sell pay per use mobile device phone fast charging stations.
Due to the urgency of this change, the BA was asked to finalize requirements elicitation in the shortest possible time.
Customers who want to utilize the pay per use mobile device fast charging stations may choose one of two features: fully charged (F1) or partially charged (F2). If partially charged is selected, the customer needs to specify their charging needs.
What is the relationship between Fl and F2?

  • A. Validate
  • B. Derive
  • C. Depends
  • D. Satisfy

I think Depends is the answer - In order to fully charge you should partially charge first.

Selected Answer: C
In this context, the feature F2 (Partially charged) depends on the selection of the charging option. If the customer selects F1 (Fully charged), F2 (Partially charged) is not needed. However, if the customer selects F2 (Partially charged), additional input (such as specifying the charging level) is required. Therefore, F2 depends on the customer’s selection.

The Answer is b-- derive. here is an extract from Babok V3 """.2 Relationships There are several types of relationships that the business analyst considers when defining the traceability approach: • Derive: relationship between two requirements, used when a requirement is derived from another requirement. This type of relationship is appropriate to link the requirements on different levels of abstraction. For example, a solution requirement derived from a business or a stakeholder requirement."

Depends: Less effort. Pg 82 When partially charged, it is easier to implement fully charged

Correct Answer is C (Depends) Justification: Validate is incorrect because it is relationship between requirement and test case. Derive is incorrect because fully charged requirement is not derived from partially charged requirement or vice versa. Satisfy is incorrect because fully charged requirement does not satisfy the partially charged requirement or vice versa. (Satisfy is usually a relationship between a requirement and a design component satisfying the requirement) Depends (by Effort) is correct because implementing Fully charged requirement would reduce the efforts for implementing partially charged requirement.

I will go with elimination . Validate is not true as it is generally between requirement and test case, Dependent is not true as two options are independent of each other Satisfy is relation ship between requirement and solution. here both are alternative solution hence derive seems to be correct

Answer B is correct, Derive. Not C, depends. I think that last sentence is very important : "if partially charged is selected....". It means that if you selected F2, you have to specify your needs, but not that F2 depends on F1. Not D, satisfy, cause we are not talking about a requirement which should satisfy an implementation or a component. Both F1 and F2 are options working the same way.

F2 seems dependant on some else elements not on F1, so I'd go with d)

Depends: relationship between two requirements, used when a requirement depends on another requirement. Types of dependency relationships include: • Necessity: when it only makes sense to implement a particular requirement if a related requirement is also implemented.
