Qualität in der Marktforschung - Schulung


We guarantee the reliability of our data and timings through a range of checks and supporting measures, as well our staff’s high levels of commitment to your project.

We consistently achieve high quality thanks to our regular interviewer training founded on theoretical concepts and our intensive supervision. To help, we use technical control tools, such as monitoring and built-in consistency and plausibility verification.

Why not see for yourself? You are more than welcome to attend the briefing, pre-testing or interviewer monitoring!

Quality - Market Research - Training


The quality of the data that we collect for you can only be as good as the level of training that the interviewer working on your project has received.

After an initial test, which examines the general level of education and eloquence of the applicant, our interviewers undergo theoretical and practical training that covers all aspects of recruitment, surveying and objection-handling. Only once an interviewer has successfully passed this training will he or she be asked to work on his or her first B2C project.

Before the start of each project, every member of staff takes part in a project-specific training session. Special advanced training sessions prepare selected interviewers for B2B projects or guided interviews.

We also provide additional training for our staff in the pharmaceutical and IT sectors to enable them to conduct complex interviews on specialist topics, meaning that they are regarded by respondents as competent discussion partners.

Quality - Market Research - Supervision


Our supervisors advise and monitor steering committees and project groups during all stages of project management.

They ensure that the work is carried out effectively and satisfactorily and that the project results are achieved thanks to their methodological expertise. They moderate and coach participants during problem-solving workshops and within interdisciplinary employee groups or quality circles.

They assist the project managers, advising on the best process, by:

  • providing qualitative diagnosis and evaluation;
  • dealing with difficult situations in change processes (solutions and intervention);
  • improving performance; and
  • carrying out evaluations (rating people and/or measures).

Quality - Market Research - Monitoring


As part of our supervision, we constantly monitor the data collected to ensure that we achieve excellent data quality and high coverage rates.

A monitoring log is developed for each project based on the client briefing, which guarantees recruitment and the correct methodological implementation of the survey and recording of responses.

Thanks to the latest technology, supervisors can connect to interviewer workstations via the watch and listen function, meaning that they can listen into and watch interviews in real-time.

Quality - Market Research - Controls


It is not sufficient simply to put together a summary at the end of the field time to ensure that a project is concluded satisfactorily for all involved.

We constantly keep you in the loop with meaningful updates, continuous reporting and interim deliveries. We set ourselves interim objectives (and welcome your input in defining them), and use them to evaluate how a project is progressing. As a general rule, as soon as ten per cent of the data has been collected, we check all parameters of the survey.

Amongst other things, this includes:

  • Data quality, paying particular attention to open responses, repetition rates for scaled questions and the prevalence of unanswered questions
  • Coverage
  • Interview durations
  • Quota achievement
  • Interviewer engagement in relation to field time
