JAD is the appropriate technique for gathering information about the As-Is and To-Be
systems: it that identifies improvements, and has a high amount of user involvement.
It is not necessary to assign dollar values to intangible costs and benefits; it is almost
impossible to come up with reasonable numbers for all of the costs and benefits that
haven”t happened yet.
Omitting all forms of the verb “to be” from documentation to create a more active
writing style follows the documentation guideline “use active voice.”
The purpose of volume tests is to push the implementation so that it may break when
there is a large amount of data required to answer a user request.
Every sequence diagram must be associated to a use case in the use-case diagram.
The creation of a design prototype that is not a working information system, but
represents a part of the system that needs additional refinement happens with the
prototyping methodology.
Content awareness is the user interface design principle that recognizes that if the user
is experienced and well aware of the content on the screens, then the design of the
screen can be simplified to take advantage of that awareness.
Interface evaluation should be performed while the system is being designed so that any
major design problems can be identified and corrected before the time and cost of
programming has been spent on a weak design.
Systems analysts Lori and Mark are employed by the local hospital. They have been
assigned to develop a very complex patient monitoring system for the cardio-care unit
using a new display technology. Throwaway prototyping is a very suitable methodology
for this project.
The normalization process is performed primarily to increase the database’s storage
efficiency.
Finding a specific object in a sequential access file is relatively easy to do.
An execution occurrence in a sequence diagram is represented using thick dashed lines
with arrows that are placed on top of the life lines.
Sergei, the project manager, is worried about completing the project on time. To
increase the productivity of his 15-person team he should create subteams with no more
than 10 people on a subteam.
The change from “Select the text you want to copy. Pressing the copy button will copy
the marked text to the new location.” to “Select the text you want to copy. Pressing the
copy button will copy the selected text to the new location.” is an application of the
guideline “use consistent terms” for crafting documentation?
Analysts must assume that users have read the manual, have attended the training
classes, and have external help nearby.
The executive summary is an important component of the system proposal because it is
used for convincing the busy executives of the merits of the project as birefly as
possible.
When selecting a design strategy an organization should consider project management
experience, project skills, functional skill development, time frame, costs, and
flexibility.
The Unified Process is not use-case driven.
Concept maps are easier to represent the nonfunctional requirements relationships than
typical textual approaches.
Given the context dimension identified by Hall on cultural difference, the level of detail
in direction could be varied between cultures.
The technical process during which the new system replaces the old system is called
installation.
A concurrent multilingual system is one that contains separate parts that are written in
each language and must be reinstalled before a specific language can be used.
A tutorial will teach people how to use a major component of the system by providing a
step-by-step or sequence of entries.
An object wrapper creates an application program interface (API) to a legacy system,
enabling object-oriented systems to interact with it.
With batch processing (sometimes called transaction processing), each input item is
entered into the system individually, usually at the same time as the event or transaction
prompting the input.
A method for improving data access that involves physically arranging the records on
the storage medium is called clustering.
All object-oriented systems development approaches are use-case driven,
architecture-centric, and iterative and incremental..
A use case that describes functionality that is complex and risky would be given a high
importance level.
Identification of the initial, final and states of the object is the final steps of building a
behavioral state diagram.
The vision document is a deliverable in the inception phase.
Denormalization of a data model reduces the number of joins that must be performed in
a query, which increases the speed of data access.
