T/F: The CRUD technique is often used to validate and enhance the list of use cases.
T
T/F: During the interviews in the user goal technique, the analyst should not try to influence the users in discussing their work methods.
F
T/F: Before using the user goal technique the analyst must first identify and classify all the types of system users.
T
T/F: One benefit of the event decomposition technique is that it helps to identify use cases at the right level of detail.
T
T/F: The event decomposition technique begins by identifying use cases.
F, begins by identifying events that occur.
T/F: The end product of the event decomposition technique is a list of use cases at the right level of analysis.
T
T/F: When describing an external event, there is no need to worry about the person or thing causing the event.
F
T/F: Temporal events always occur on a fixed date or at a fixed time.
F, it occurs as a result of reaching a point in time.
T/F: A state event is a political or governmental activity.
F
T/F: Another name for a state event is an internal event
T
T/F: When a customer buys an item of merchandise using his store credit account, a separate event is required to pay the store.
T
T/F: Another name for the “includes” relationship is the “uses” relationship.
T
T/F: During analysis the analyst should be sure to identify system control events such as the user logging in or out.
F
T/F: CRUD stands for create, reply, update, delete.
F, it is read not reply.
T/F: The CRUD technique is most useful as a cross-check along with other techniques.
T
T/F: When using the CRUD technique, data ownership by foreign systems is an important consideration.
T
T/F: One way to determine whether an occurrence is an event or part of the interaction before or after an event is by asking if any long pauses or intervals occur.
T
T/F: A state event is an event that occurs when something happens outside the system that triggers the need for processing.
F, External not state.
T/F: Real-time systems require the system to react immediately to things that are going on in the environment.
T
T/F: The focus on external events is inappropriate when working with end users because discussing events tends to confuse the issues.
F
T/F: The focus on external events is inappropriate when working with end users because discussing events tends to confuse the issues.
F
T/F: One technique used to help decide which events apply to controls is to assume that technology is perfect.
T
T/F: An actor is a person that plays a particular role within a business process.
F
T/F: An actor is a person that plays a particular role within a business process.
F
T/F: In a use case diagram an actor must always be a person.

automation boundary
The _______ technique is a technique to identify use cases by determining specific goals or objectives must be completed by a user.
user goal
An event that occurs when something inside the system triggers the need for processing, but usually as a consequence of external activity is called a _______ event.
state
An event that occurs outside the system is called a(n) _______.
external event
The _______ technique is a technique to identify use cases by determining the external business events to which the system must respond.
event decomposition
List three types of events and provide descriptions for each.
An external event is an event that occurs outside the system and is usually initiated by an external agent or actor. A second type of event is the temporal, which occurs as a result of reaching a point in time. A third type of even is a state event. This event occurs when something happens inside the system that triggers the need for processing.
