CBAP Exam - Question 238

Question

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?

Examice · Accepted Answer

The relationship between F1 (fully charged) and F2 (partially charged) is a 'Depends' relationship because the choice to fully charge inherently includes the option to partially charge the device. For a customer to fully charge their device, it necessitates that the device can also be partially charged, even though the opposite is not necessarily true. Therefore, F2 is dependent on the capability to perform F1, but F1 is not derived from F2 and does not merely satisfy or validate anything.

[Removed] · Answer

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

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.

NickMane · Answer

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

smyyyy · Answer

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

hantran · Answer

I think It is D. Satisfy

rhsdeal · Answer

Answer is B: V-3 5.1.4.2 Requirements Life cycle Management; Trace requirements; Elements; Relationships - • 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.

HSinghM · Answer

Correct, D

OlivierPaudex · Answer

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.

SDab · Answer

Answer B : partial charging has been derived from the need to have full charging. (
derived requirement represent a need that can meet the intention of the original requirement)

Farooq_95 · Answer

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.

BABOK V3 pg 81: 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.

Inzaghi78 · Answer

the relationship between feature F1 (fully charged) and feature F2 (partially charged) is that F2 depends on F1
