Certification mark for certified software quality

The standard ISO/IEC 25051:2014 "Software engineering — Systems and software Quality Requirements and Evaluation (SQuaRE) — Requirements for quality of Ready to Use Software Product (RUSP) and instructions for testing" is used as the basis for the requirements for the functional aspects of software quality (e.g. correctness, completeness, robustness).

Quality assurance, documentation and process quality are considered as part of an ISO 19011-based audit. This is intended to ensure that the quality level currently achieved can be maintained in the long term.

The aspects of usability are tested based on the standard DIN / EN / ISO 9241-110:2020 "Ergonomics of human-system interaction – Part 110: Interaction principles".

The aim is to ensure that the software is designed to be user-friendly and takes into account the needs and abilities of the user in order to ensure efficient and satisfactory interaction.

The software or product has been tested independently and is compliant to applicable accessibility norms and regulations in the European Union like the European Accessibility Act.

Tested parts include for example the handling of visual presentation and media, as well as the general usage experience.

The testing is defined in the legal framework and includes all core functions as well as samples from other areas.

All tested parts of the provided software-version have proven usable for people with disabilities without needing the assistance of others.

The software product is tested and certified for conformity with the principles of proper IT-based accounting systems (German: Grundsätze ordnungsgemäßer Buchhaltung (GoBS)) in accordance with standard IDW PS 880, with the aim of checking and confirming the correctness, reliability and accuracy of the data processed in the software.
