Expert Evaluations

Usability testing is an essential part of the usability engineering process to evaluate the effectiveness, efficiency and satisfaction of system use (according to DIN EN ISO 9241, part 11). Already at an early stage components of the respective system components should be tested and evaluated, in order to identify usability problems as soon as possible and to derive suggestions for their improvement.

Upon completion, the usability of the whole system is evaluated in a final comprehensive quality assessment.
ExpertenevaluationEvaluation tests are performed according to relevant outcome measures by experts and/or users. For a qualitative evaluation of the system, expert evaluations such as a cognitive walkthrough or heuristic evaluation are particularly suitable. We support you by preparing, implementing and evaluating your surveys, in which we identify strengths and weaknesses of your product/system and derive design recommendations for further development. This guarantees enhanced usability and high quality for your product/system.
