The Public Procurement Act defines a relatively wide range of procurement procedures for goods and services. Nevertheless, public procurers choose mostly the open procedure or the restricted procedure, even for the procurement of custom (tailor-made) software (SW) works, where other, less used procedures such as the design contest and the competitive dialogue would be more suitable. From current practice there are typical problems in procurement of such SW works. By comparing the chosen public procurement procedures we will try to find answer to question which of the public procurement procedures is best suited to eliminating the risks of SW works procurement and how to deal with the custom SW work procurement so that the work is delivered in the required quality, with the highest degree of responsibility of the best-prepared supplier in the shortest possible time.
