The purpose of the revision is to harmonise the partly heterogeneous federal and cantonal public procurement regulations as far as possible. With new sanction instruments, the procuring entities can issue warnings, procurement bans and, at the cantonal level, fines against non-compliant suppliers. The revision leads to a stronger focus on quality competition. Now it is no longer the "most economically favourable" tender that wins the contract, but the "most advantageous" tender.
