One of the essential changes in the procurement law reform of 2016 is a new perspective on economic efficiency. According to the new procurement guidelines, there should be a stronger focus on quality, sustainability, and innovation in awarding contracts. Therefore, the contract should ideally be awarded to the offer with the best price-performance ratio. This requires a deeper understanding of evaluation methods and evaluation matrices in the preparation and execution of procurement procedures to answer the questions "What additional performance justifies a higher price?" and "What relationship must prices/costs and performance have to achieve an optimal result?" The title "Evaluation Criteria and Matrices in the Procurement Process" addresses these central issues of the procurement law reform and guides you through them effectively.
