Tender Evaluation and Award Methodologies in Public Procurement
The EU procurement directives stipulate that public contracts are awarded to the lowest bidder or to the bidder with the economically most advantageous offer; the latter requiring that a scoring rule must be specified. We provide a simple theoretical framework for tender evaluation and discuss the pros and cons of common scoring rules, e.g., highest quality (beauty contest) and price-and-quality-based evaluation. Some descriptive facts are presented for a sample of Swedish public procurements. We argue that the most common method, price-to-quality scoring, is flawed for several reasons. It is non-transparent, making accurate representation of the procurer’s preferences difficult. It is often open to strategic manipulation, due to dependence on irrelevant alternatives, and it is unreasonably non-linear in bid prices. We prefer quality-to-price scoring, where money values are assigned to different quality levels. When the costs of quality are relatively well-known, however, lowest price is the preferable award criteria.
