In one of the missions I was assigned to, we were looking at the High-End Audio Equipment Industry (e.g. high-end speakers, amplifiers, etc.). To assess the attractiveness of this market, our goal was to understand the addressed market size (current owners of high-end audio equipment) and the addressable market size (potential owners of high-end audio equipment). For this mission, I was in charge of the conduction of a customer survey around this topic. This was a great responsibility since the survey output data represented an important amount of the information required for the solving of the case and accounted for a significant share of the case budget (e.g. around 10k€). I monitored the survey process top-down, from the writing of the different questions, the supervising of the survey coding (sub-contracted to a professional survey coder), the monitoring of the collected answers to the final quantitative analysis of the data. This task involved a lot of communication with my team members since, at each step, the survey was reviewed internally by the different missions’ managers and reiterated several times. Furthermore, I considerably contributed to the case-solving through the quantitative analysis of the survey data, which proved to be very informative and useful. However, I encountered several challenges during this task. Indeed, once the coding was finalized, we conducted a soft launch step: the survey is sent to potential respondents and stopped when 30 answers are collected. This is used as a test step before the full launch to verify that all questions are asked correctly. At this stage, when analyzing the soft launch responses, I noticed that a lot of respondents were lying to some questions in order to pass the survey screening (the stage beyond which respondents are paid). This was not an expected challenge at the beginning of the process, however I was able to overcome this by adding ‘test / trick questions’ and logic to the survey to screen out immediately all lying respondents. As a consequence, the answers collection process was slowed down. However, all answers were then very reliable which was greatly appreciated by my supervisors. Despite the various challenges, this task was achieved successfully as deadlines were met and the survey analysis contributed strongly to the case solving.
