| Latest edition | 1994-10 (withdrawn without replacement) |
| ISO | ISO / IEC 9126 |
In the DIN standard DIN 66272 were quality features for software defined. The standard was withdrawn without replacement in May 2006 by DIN.
The six main quality characteristics are: functionality , reliability , usability, efficiency , changeability, transferability . These correspond to the main features of software quality according to ISO / IEC 9126 .
- Functionality
- This quality feature shows whether all the required functions have been implemented and can be carried out.
- reliability
- The reliability assesses the availability and accuracy of the software. It is determined on the basis of predefined test patterns .
- Usability
- Usability ( English usability ) is the ease of use . How can the program be operated? How easy is it to learn the software? How do you react to incorrect entries? In order to keep the training effort as low as possible, an intuitive usability is usually aimed for.
- Efficiency
- The efficiency expresses the temporal behavior for inquiries and processing as well as the resource consumption with regard to storage capacity and system requirements .
- Changeability
- Effort to implement improvements, to correct errors or to adapt to changes in the environment.
- Transferability
- This feature expresses whether the software can also be used on other systems (hardware and software).
