The Swiss Coordination System for Business Surveys

The Swiss Coordination System for business surveys is operational since 2009. By september 2015 it has allowed to select 56 samples and subsamples for 20 different surveys. This system can coordinate a sequence of samples positively or negatively by maximizing or minimizing their expected overlap. The system also enables to define an order of priority on the past surveys with which the current sample is coordinated. It is compatible with a dynamic population where units can appear or disappear over time. It also allows for an unconstrained choice of inclusion probabilities for all units in the population.
We will present the main principles of this system and discuss the main challenges we had to face for its implementation.
