Made to Measure

This is our signature. We offer exploratory approaches with a high degree of personalisation and a method adapted to each project, far from pre-built models and preconceived ideas.

This enables us to go further and leave behind the silo mentality, in line with the changes in the society, organisations and regions we survey. The blend of methods (online + telephone, quantitative + qualitative, ‘hot’ and ‘cold’ strategies, etc.) opens an infinite number of exploratory opportunities to create new approaches.

This is both our favourite quality and our signature, fuelled by the variety of subjects explored. It’s second nature to us, leading us on a discovery of new sectors, new services and new behaviour, accompanied by our thirst for knowledge and the desire for fuller understanding.

Our profession

At the crossroads of strategy, consultancy and operational steering, we guide you along all or part of the production of your survey, according to your needs. A ‘pick and choose’ or an ‘all-in’ package – the choice is yours ! Behind the data and the figures, there is also a human experience we invite you and your audience on.

institut d'études notre métier

Designing a survey device

We have a conviction at COHDA; launching a survey without in-depth preparation is like hoping to cross the Pacific Ocean on a paddleboard – there’s little chance of getting very far! In other words, a successful study begins with choosing the right method and cannot be designed without working alongside your teams.

Data collection

COHDA provides all the means of gathering data which will capture the attention of your targets and obtain their participation, via its platform for in-house contacts or its solid partnerships with French start-ups.

Results analysis, presentation and advice

Our experts love making numbers meaningful, uncovering the secrets of a memorable customer/citizen experience, capturing insights and decoding emerging behaviour, and can offer a range of ways to share the fruit of their analysis and their discoveries with you.
