Deck 1: Analyzing System Interactions, Walkthroughs, and Use-Case Point Estimation

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

Answer 1

common or global

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

Answer 3

simple, average, or complex

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.

Question 5

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

Question 6

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

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).

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).

Question 9

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

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.
