Did you know that the focusing on performance, function, duty or role of the goods or services significantly increases the number of potential suppliers, competition and improves the results of the tender? Basically there are three types of specifications:
Functional specifications define the task or desired result by focusing on what is to be achieved rather than how it is to be done. Performance specifications define the purpose of the goods or services in terms of how effectively it will perform. Technical specifications define the technical and physical characteristics and/or measurements of a product. All three types may be combined to form the one specification.
It should be mentioned that performance and functional specifications do not limit responses to specific procurement object and enable suppliers to provide different solutions to defined needs. As a result, the competition increases. Therefore, it is recommended in the procurement literature as well as in the (e.g. Georgian) public procurement legislation the use of performance and functional specifications rather than technical specifications. Technical characteristics may be needed to define some requirements more clearly.
