Abstract
The paper proposes an extension of the Gero’s Function-Behaviour-Structure (FBS) framework aimed at representing Need and Requirements and their relationships with the Function, the Behaviour and the Structure of an artefact. Needs and Requirements can be modelled as further types of variables to describe with the same formal approach of the situated FBS model the transformation processes which occur in the earlier stages of design, when the requirements still need to be specified. The proposed model is clarified through a simple, but comprehensive example related to the design of a kettle.
