Data-Gathering Techniques, Their Advantages, and Their Di
sadvantages
A variation on basic observation is
protocol analysis
in which the worker "thinks aloud"
while solving a problem
true
Finally, it should be remembered that modeling is a means to
document requirements. The process models, information models, and organizational models all document system requirements in a way that textual descriptions cannot
true
The problem analysis, stakeholder analysis, and requireme
nts engineering activities are
recorded in reports that become part of the project's delive
rables. The reports generated
are:
1. Problem Analysis Report
2. Stakeholder Report
3. Requirements Document
Al-sasi / Questionnaires data gathering can easily help to obtain a statistically significant response rate.
(false)

Al-sasi / Questionnaires data gathering cannot help to obtain a statistically significant response rate.
Strong Requirement: The organization will have ISO 9000 certification when it starts operation
(false)


Weak Requirement: The organization will have ISO 9000 certification when it starts operation
Strong Requirement: The production line will be capable of operating at 85% capacity 24 hours a day, 7 days a week This requirement allows for some slack time for maintenance and also observes that performance must trade off speed and capacity.
(true)
The used data-gathering strategy is a component of the problem analysis report along with a summation of the data, list of the problems identified in the Problem Statement List, and an analysis of the causes and effect of those problems.
(true)
The production line will be capable of operating at 100% capacity 24 hours a day, 7 days a week" is a strong requirements statement.
(false)
/ Changes in the worker's behavior is less likely or at the very least level if she/he is being observed using (fly on the wall ).
(true)
7/ Functional requirements describe property or characteristics of the system that stakeholders deem important and will affect their degree of satisfaction with the enterprise.
(false)



7/ Non-functional requirements describe property or characteristics of the system that stakeholders deem important and will affect their degree of satisfaction with the enterprise.
8/ The analyst can better understand the business process by interviewing the business owner rather than employees involved in the process
False
Requirements workshops cut across organizational boundaries and involve only stakeholders within the enterprise.
false
10/ The goal of requirements engineering is to obtain a complete but minimum set of requirements the system must satisfy
True
/ Observing the average operations is the most common practice when using the observing technique to gather or collect data.
(false)


the best
Data gathering is a cross life-cycle activity done throughout multiple phases but predominantly during the analysis
(true)
Over the lifetime of the project, it is not very common for existing requirements to change.
(false)
14/ There is no need to record the date and time nor the description of the observation context if the observation is reported after the time of observation.
(false)
15/ Requirements validation includes maintaining unidirectional traceability of requirements, i.e. traceability from the source requirement to its lower-level requirements and from the lower-level requirements back to their source.
(F)


15/ Requirements validation includes maintaining bidirectional traceability of requirements, i.e. traceability from the source requirement to its lower-level requirements and from the lower-level requirements back to their source.
16/ Priority stakeholders are interviewed to gain accurate information on their interests, and ability to affect the project, but not their positions.
(false)
17/ The ideal time limit for the interview can go beyond one hour.
true
18/ A good objective statements is: "To improve system output without increasing the number of employees."
(false)
19/ Casual loop diagrams can be used to better represent most of the complex cause-effect relationships.
(true)
21/ Recording the observation can be done on the spot or the analyst might record their observations after the observation.
(true)
22/ Stakeholder analysis is mainly conducted to study the interactions take place between various stakeholders of the enterprise
(false)
23/ Printed documentations provide better information and understanding of management operations and procedures than what can be obtained from observation or even interviews of participants.
(false)
24/ A business rule describes how the enterprise operates and these business rules are discovered during requirement gathering
(true)
25/ The analyst should avoid asking any follow-up questions and work on interpreting the exact given answers by interviewees
(false)
26/ The fishbone diagram is usually used to overcome the limitation of linear thinking underlying traditional cause/effect diagramming techniques
(false)
