AUDITS

Go-live audit

GO-LIVE AUDIT

Ensure the alignment of an audience measurement system with the project specifications and the international standards, during its set up phase or extension (multi-screen measurement, TV out-of-home measurement…)

▶ Evaluation of the new TV and video multi-screen measurement system in Singapore including smartphone, tablet and computer

An independent audit of any service is important, but I think it is particularly crucial where new multi-screen measurements are being launched as in Singapore. This helps to improve the measurement and also offers a level of transparency that can assure the industry that proper processes are in place.”

Lee RISK GfK commercial director APAC

FULL AUDIT

A transparent and full evaluation of a measurement system according to the international guidelines

▶ Audit of TV, video and radio audience measurement systems in the Netherlands

In 2018, We have built a completely new household panel for the TV, online and video ratings and an individual panel for radio & online ratings. Both systems were audited on method by CESP, giving the market the confidence of the service. We have also worked with CESP for a technical review of the audiomatching technology for the radio ratings. CESP has a very thorough approach, while as a client the workload is manageable. CESP has a flexible mindset and is open for discussions. The scientific committee with which CESP works for recommendation has added value for market acceptance

▶ Consulting mission to support a television audience measurement tender in Croatia

Throughout this process, we engaged CESP as our consulting partner, and working with them on this tender has been an exceptional experience. CESP expertise proved invaluable in steering the process toward a successful outcome.

▶ Consulting to support a media measurement tender in Thailand

The main benefit of CESP support on the project is the experience and expertise they are bringing to our new JIC based on their academic knowledge and international experiences of multiscreen measurement. On top of their huge experience in media measurement, the CESP consultants are fully supportive and tough negotiators. They do not compromise for less whether it is technical, timeline or penalty during the final contract negotiation; but also advise on fairness for the research companies.

▶ Consulting mission to support a television audience measurement tender in the Philippines

The Philippine TV advertising industry has long faced the challenge of two different TV audience measurement systems. In the last couple of years, our industry united to aim for a single measurement system and the first step was to conduct an audit of the two systems. CESP with its brillant team headed by Olivier Daufresne conducted this audit with professionalism and responsiveness. Today we continue to engage CESP for our multi-screen measurement project, as we believe they are the only company that can help us move forward smoothly.

TECHNICAL TESTS

Independent audit of the reliability of an audience measurement technology

▶ Test of portable meters measuring TV out-of-home audience in Poland

The CESP team is composed of professionals who deeply understand the complexities of media research and the expectations of its end users. I was highly impressed by their expertise in conducting audits, as well as their fresh perspective, open-minded approach, and appreciation for the innovative nature of our solutions. The CESP audit of the Gemius TV OOH survey in Poland not only confirmed the quality of our results but also identified new development opportunities, which we successfully implemented in collaboration with our clients.

▶ Test of the portable meters measuring TV out-of-home audience in Czech Republic

In December 2024, we asked CESP to audit our technology for measuring television viewership using audio matching within mobile phones. The cooperation was very professional.

CESP’s confirmation that we are able to deliver mobile measured viewership helped us establish the technology with the media industry.”
