To complete a 20 person-month project in 10 months, a team should have 4 full-time
staff members assigned to the project.
Packaged diagrams cannot be verified or validated since they are too general.
In the UML, the Deployment Diagram is a behavioral diagram that illustrates the
dynamic interaction of the system with its environment.
Acceptance testing is done in two stages: alpha testing, where users test the system
using made-up data, and beta testing, where users begin to use the system with real data
but are carefully monitored for errors.
The four most common approaches have been suggested to aid the analyst in
identifying a set of candidate objects for the structural model are textual analysis,
brainstorming, common object lists, and design patterns.
The underlying cause of many missed project deadlines is scope creep.
Programming can be the greatest single component of any information systems
development project in terms of time and cost.
There are three key roles in any major organizational change. The three keys are
sponsor of the change, the change agents, and the potential adopters.
When one or more locations or units within a organization are selected to be converted
first as part of a pilot test, this is called phased conversion.
Direct conversion is the conversion style where both systems (as-is and to-be) are used
simultaneously.
When looking for a specific object of interest, on average 25% of a sequential access
file will have to be searched in order to find that object.
Novice and expert users are both usually most concerned with “ease of use” of a new
system.
System requests often include the project team members including the project
manager and the analysts.
When planning a systems project, overly optimistic timetables are the cause of project
completion delays.
The number of errors found will be lowest in the unit testing stage of testing.
The organizational management of a business is involved in hands-on activities related
to the project.
All parts of the interface, whether navigation, input, or output, should provide as much
content awareness as possible, but it is particularly important for forms or reports that
are used quickly or irregularly.
An interview style that seeks a broad and roughly defined set of information is
commonly called the unstructured interview style.
The Unified Modeling Language is a collection of terms and diagrams designed to be
used in object-oriented software projects
One of the most common causes for schedule problems is scope creep
Constraints can only be written in either a semiformal language or a formal language.
An analysis team consisting of users, managers, and analysts, are in the midst of a
daylong meeting. They are working on systematically evaluating the consequences of
removing every activity from the current business process. The team is performing
activity-based costing.
It is much less efficient to buy packaged software that has already been created, tested,
and proven than to build a system from scratch.
Direct conversion, where the new system is turned on and the old system is
immediately turned off, is the simplest and most straightforward method, but it is also
the most risky because any problems with the new system may seriously disrupt the
organization.
The set of rules used for verifying and validating the structural model is to check the
consistency between CRC cards and class diagrams of the structural model.
Abstract classes are used to create objects.
One of advantage of concept maps over typical textual approach is that concepts maps
allow the relationships among the functional and nonfunctional requirements to be
explicitly represented.
In the server-based architecture, all data stored on one computer.
The infrastructure analyst is responsible for the design of the new business policies and
processes.
Performance testing typically falls into two categories: stress tests and volume tests.
Christine does not have the skills that her project manager feels are necessary and no
money has been budgeted for outside consultants. Mentoring is a good option to
improve Christine’s skills in this situation.
In general, for any change that has true organizational benefits, about 50 percent of
potential adopters will be ready adopters, and another 50 percent are resistant adopters.
