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. To meet your requirements, our multidisciplinary team, organised according to various fields of expertise (sales, marketing, statistics and production) and a seamless structure fostering the diversity of skills and viewpoints can define the best approach and advise you in :
The study technique to choose :
Mystery survey, benchmark study, mirror survey, quality monitoring, in situ information gathering, etc., there is a vaster range of investigation techniques available to you than you might think.
Evaluation frequency :
Hot or cold, barometric, one-shot, etc., because establishing temporality is key to engaging customers, employees or citizens more effectively.
The collection method(s):
Closely linked to the study theme, to the aims of the device, the allocated budget and the audience to be surveyed (BtoB, BtoC, specific niches, ultra-targeted consumers, etc.), this is a strategic factor !
The design of the questionnaire or evaluation grid :
The choice of wording, the duration, question hierarchy techniques, evaluation scales, etc., are just as important, regardless of the chosen collection method (telephone, online, social media, SMS, and so on) and imply appropriate formulation and register.
The sampling method :
Representation of the population (random method, quotas, judgemental sampling, etc.), exhaustive exploitation, oversampling of strategic targets, and so on; these are decisive considerations for the exploitation and extrapolation of results.
File strategy :
Where necessary, we can make use of the best contact files on the market and/or enrich your own files.
