Question 1

When a global data area exists outside individual objects, the resulting system has _____ interaction coupling.
A) stamp
B) data
C) content or pathological
D) common or global
E) control

Accepted Answer

When a global data area exists outside individual objects and is accessed by multiple objects, the resulting system has common or global interaction coupling. This is because the objects are coupled through their shared access to the global data area.

Question 2

What is a walkthrough?
Ans. A walkthrough is a peer-review of a product. They can be used to verify and validate the models developed during analysis. Members of the walkthrough come from the client, the analysis team, and the design team. A presenter "walks" the team through the models. The team members are free to ask questions. The goal is identify errors. A scribe or recorder makes notes of the errors and problems identified by the team so these can fixed later. The team does not fix the problems, they are here to find problem spot only. To ensure reusability of the models that were developed, a special person called the "maintenance oracle" asks questions regarding maintenance of the models. The analysis team will correct the errors before handing the project over to the design team. Response: See page 273-274

Question 3

In estimating size and effort using use-case points, once the use-cases and use case diagram have been created, the actors and use cases must be classified as _____, _____, or ______.
A) incremental, average, or radical
B) small, average, or large
C) simple, average, or complex
D) discretionary, average, or urgent
E) open, average, or closed

Accepted Answer

Use cases and actors in use-case point estimation are classified as simple, average, or complex to help in assessing the effort and size of a software project more accurately. This classification helps in determining the complexity and thereby the effort required for implementation.

Question 4

The value of the unadjusted use-case points weight total (UUCW) is the sum of the number of unique transactions in each of the use cases.

Accepted Answer

The value of the Unadjusted Use-Case Weight (UUCW) is determined by classifying each use case as simple, average, or complex and then applying a predefined weight to each classification before summing them up, not merely by summing the number of unique transactions.

Question 5

A use case with seven unique transactions contributes ten unadjusted use-case points.

Accepted Answer

A use case with seven unique transactions contributes ten unadjusted use-case points because each transaction is worth one unadjusted use-case point.

Question 6

A use case with eight unique transactions contributes fifteen unadjusted use-case points.

Accepted Answer

The number of unadjusted use-case points is equal to the number of unique transactions in the use case.

Question 7

To compute the adjusted use-case points (UCP), the unadjusted use-case points weight total (UUCW) is multiplied by the technical complexity factor (TCF), the environmental complexity factor (ECF), and the business-impact factor (BIF).

Accepted Answer

To compute the adjusted use-case points (UCP), the unadjusted use-case points (UUCW) are multiplied by the technical complexity factor (TCF) and the environmental complexity factor (ECF), but there is no standard business-impact factor (BIF) in the traditional UCP calculation method.

Question 8

To compute the adjusted use-case points (UCP), the unadjusted use-case points weight total (UUCW) is multiplied by the technical complexity factor (TCF) and the environmental complexity factor (ECF).

Accepted Answer

The adjusted use-case points (UCP) are calculated by multiplying the unadjusted use-case points weight total (UUCW) by both the technical complexity factor (TCF) and the environmental complexity factor (ECF), which adjusts the UUCW for technical and environmental complexities.

Question 9

Distinguish between control flows and object flows in an activity diagram.

Accepted Answer

The answer of Distinguish between control flows and object flows...

Question 10

Erica has completed the use-case point analysis for the system she is building and found that it has 12 unadjusted actor weight points (UAW), 70 unadjusted use-case weight total (UUCW), a technical factor (Tfactor) of 15 and an environmental factor (Efactor) of 21. In computing this Efactor value Erica accounted for the fact that although she is very experienced, has top-notch technical skills, knows how to motivate her teams, her team for this project is partially staffed with part-timers who are not familiar with the system development process being used and who lack object-oriented experience. In other words, she has three environmental factors that count towards the person-hours multiplier (PHM).
(a) How many person-hours will it take Erica to complete the project?
(b) Next suppose that in addition to these three environmental difficulties, that she has two more strikes against her: the programming language being used is very difficult and the requirements are not stable. Should Erica rethink taking on this project? Explain.

Accepted Answer

The answer of Erica has completed the use-case point analysis...
