We have our own Quality Assurance department, which specialises in the quality assurance of online questionnaires. The questionnaires programmed by the IT specialists are checked several times for formal, technical and content correctness and functionality using fixed checklists. In addition to the conformity with your template and the functionality of all filter guides, multimedia elements and randomisations, our experts also examine the logic of the questionnaire structure, the comprehensibility of the questions and answers as well as the correct mapping and coherence of various scales in relation to the question.
