Documentation

MTBF is a measurement of ________ occurrences that can be tracked over time to indicate the quality of a system.

As part of logical design, analysts design the various parts of the system to perform the physical operations necessary to facilitate data capture, processing, and information output.

False

Desk checking is the process of bringing together all of the modules that a program comprises for testing purposes.

False

It is not crucial that help desk personnel know when new systems and releases are being implemented and when users are being trained for new systems.

False

The Agile Methodologies focus on the roles that people perform rather than placing the emphasis on individuals.

False

The life cycle can be thought of as a linear process in which the end of the useful life of one system leads to the beginning of another project that will develop a new version or replace an existing system altogether.

False

The user guide is the deliverable that is produced after the ________ phase.

Installation

The user training plan is the deliverable that is produced after the ________ phase.

Installation

Which maintainability factor specifies the number of unknown errors existing in the system after it is installed?

Latent defects

Systems with ________ maintainability result in uncontrollable maintenance expenses.

Low

In which phase of the SDLC is an information system systematically repaired and improved?

Maintenance

Measuring the number of and time between failures will provide you with the basis to calculate a widely used measure of system quality. This metric is referred to as ________.

Mean time between failures

Which of the following is a component of the Maintenance phase of the SDLC?

New versions or releases of software with associated updates to documentation, training, and support

Which activity in the maintenance phase requires that a formal process be established whereby users can submit system change requests?

Obtaining maintenance requests

Which maintenance involves making enhancements to improve processing performance or interface usability or to add desired, but not necessarily required, system features?

Perfective

Which installation changes from the old information system to the new one incrementally, starting with one or a few functional components and then gradually extends the installation to cover the whole new system?

Phased installation

Which SDLC phase is analogous to the maintenance process of obtaining a maintenance request?

Planning

Which of the following is NOT valued according to the Agile Manifesto for software development?

Project Manager

Which of the following is NOT a criticism of the traditional waterfall SDLC approach?

Reverse engineering

Which of the below is a traditional methodology used to develop, maintain, and replace information systems?

SDLC

"Formal transfer of systems between groups improves the system and documentation quality" is an advantage of which maintenance organizational structure?

Separate

________ testing is defined as the process of bringing together all of the programs that a system comprises for testing purposes.

System

Who is responsible for controlling the checking out and checking in of baseline modules for a system when a system is being developed or maintained?

System Librarian

Which implementation factor includes aspects of the system's design such as ease of use, reliability, and relevance to the task the system supports?

System characteristics

________ is more than simply expanded integration testing, where you are testing the interfaces between programs in a system rather than testing the interfaces between modules in a program.

System testing

Attempts to make systems development less of an art and more of a science are usually referred to as ________.

Systems engineering

________ is/are the process(es) that an analyst will follow to help ensure that his work is complete, well-done, and understood by project team members.

Techniques

A primary objective of using automated tools for systems development and maintenance is to radically change the way in which code and documentation are modified and updated.

True

Because the maintenance phase of the SDLC is basically a subset of the activities of the entire development process, the deliverables and outcomes from the process are the development of a new version of the software and new versions of all design documents developed or modified during the maintenance process.

True

Computer-aided software engineering (CASE) tools were developed to make systems developers' work easier and more consistent.

True

In the maintenance phase, the systems development group is responsible for collecting maintenance requests from the network management staff.

Over the life of a system, corrective maintenance is most likely to occur after initial system installation or after major system changes. This means that adaptive, perfective, and preventive maintenance activities can lead to corrective maintenance activities if not carefully designed and implemented.

True

Support means providing ongoing educational and problem-solving assistance to information system users. For in-house developed systems, support materials and jobs will have to be prepared or designed as part of the implementation process.

True

System bugs can be identified during the testing process.

True

System testing is more than simply expanded integration testing where you are testing the interfaces between programs in a system rather than testing the interfaces between modules in a program.
