|
FALSE |
The error can not be corrected by built-in
error detection and recovery. |

Generic |
These are software products developed to be
sold to a range of different customers. |

Identify quality, cost or schedule bottlenecks |
|
System failure |
An event that occurs at some point in time
when the system does not deliver a service as expected by its users. |
|
TRUE |
A poorly designed interface can cause a user
to make catastrophic errors. |

The ability of the system to operate without
catastrophic failure. |
|
Customized, |
These are developed software for a single
customer according to their specification (select all that applies) |
|
Software Engineers |
They are I.T. practitioners who adopt a
systematic and organised approach to their work and use appropriate tools and
techniques depending on the problem to be solved, the development constraints
and the resources available. |
|
Process change introduction |
Modify the process to remove identified
bottlenecks |
|
Availability |
The ability of the system to deliver services
when requested. |
|
TRUE |
Dependability costs tend to increase
exponentially as increasing levels of dependability are required. |
|
recoverability |
It is a UI design principle that allows user
to recover from errors. |
|
Software Engineer |
It is focused on cost effective software
development. |
|
TRUE |
Because of very high costs of dependability
achievement, it may be more cost effective to accept untrustworthy systems
and pay for failure costs. |
|
None among the choices |
Some of the components of User interface
design process. (select all that applies) |
|
The correct answer i |
The use of more expensive development
techniques and hardware that are required to achieve the higher levels of
dependability decreases the cost of dependability of software. |
|
Reliability |
The probability of failure-free system
operation over a specified time in a given environment for a given purpose. |
|
TRUE |
Designers should be aware of people’s physical
and mental limitations. |
|
Technical cost |
This factor often dominates system costs in a
system development |
|
Survivability |
It subsumes the notion of resilience - the
ability of a system to continue in operation in spite of component failures. |
|
Change tuning |
Evolve and improve process improvements |
|
Specification |
Part of the generic activity of software
development which checks what the system should do and its development
constraints. |
|
Software Engineering |
It is concerned with theories, methods and
tools for professional software development |
|
Process change training |
Train staff involved in new process proposals |
|
FALSE |
The use of more expensive development
techniques and hardware that are required to achieve the higher levels of
dependability decreases the cost of dependability of software. |
|
Reliability |
The ability of the system to deliver services
as specified. |
|
System error |
Erroneous system behavior where the behavior
of the system does not conform to its specification. |
|
Software Engineering |
It is focused on cost effective software
development. |
|
Validation |
The process of checking that the software is
what the customer wants. |
|
System fault |
An incorrect system state i .e . a system
state that is unexpected by the designers of the system. |
|
FALSE |
The increased testing and system validation
that is required to convince the system client that the required levels of
dependability have been achieved decreases the cost of dependability of
software |
|
ISO 9000 |
International set of standards for quality
management. |
|
Maintainability |
A system attribute which is concerned with the
ease of repairing the system after a failure has been discovered or changing
the system to include new features. |
|
Availability |
The probability that a system, at a point in
time, will be operational and able to deliver the requested services. |
|
Survivability |
This is an increasingly important attribute
for distributed systems whose security can be compromised. |
|
level 2 |
Organizations rated as ______ in the CMM are
likely to be ISO 9000 compliant |
|
User-centered design |
It is an approach to UI design where the needs
of the user are paramount and where the user is involved in the design
process. |
|
TRUE |
Errors do not necessarily lead to system
failures. |
|

It is a UI design principle that provides
appropriate interaction facilities for different types of system user. |
|
The correct answers are: Customized, Bespoke |
These are developed software for a single
customer according to their specification (select all that applies) |
|
Dependability |
It reflects the extent of the user’s
confidence that it will operate as users expect and that it will not ‘fail’
in normal use. |
|
