 Modularity - the resulting software comprises well defined,
independent components. That leads to better maintainability.
The components could be then implemented and tested in
isolation before being integrated to form a desired software
system. This allows division of work in a software
development project.
 Reliability - The software is able to perform a required
function under stated conditions for a specified period of
time.
 Reusability - the software is able to add further features and
modification with slight or no modification.
 Robustness - The software is able to operate under stress or
tolerate unpredictable or invalid input. For example, it can be
designed with a resilience to low memory conditions.
 Security - The software is able to withstand hostile acts and
influences.
 Usability - The software user interface must be usable for its
target user/audience. Default values for the parameters must
be chosen so that they are a good choice for the majority of
the users.
