Software Performance
The performance of the Alert Messaging system depends upon the
speed and efficiency of the user’s computer & the network
speed.
Reliability
Reliability is an important element of its overall software quality.
If a program repeatedly and frequently fails to perform, it matters
little whether other software quality factors are acceptable.
Software reliability can be defined in statistical terms as the
"probability of failure-free" operation of a computer
program in a specified environment for specified time. For instance,
program X is estimated to have reliability of 0.94 over five elapsed
processing hours. In other words, if program X were to be executed
100 times and require five hours of elapsed execution time, it is
likely to operate correctly (without failure) 94 times out of 100.
The application (project) developed by us has a reliability of
0.96 over six elapsed processing hours.
Software Quality Measures
Although there are several measures of software quality, we have
taken the following measures as an indicator in this project:
- Correctness
- Maintenance
- Integrity
- Usability
- Efficiency
- Portability
The above factors do not necessarily lend themselves to direct
measurement. However, they provide a worthwhile basis for indirect
measures and an excellent checklist for assessing the quality of
the system.
While developing the project, we have kept these measures in mind
as an indicator of quality.
