Technological Modelling
Abstract
The purpose of this explanatory paper is to define technological modelling and clarify the role and nature of functional modelling and prototyping. It presents the component descriptor, the key ideas underpinning it, and illustrative examples of these from technology. This paper also suggests possible learning experiences.
Component descriptor
Technological modelling refers to modelling practices used to enhance technological developments and includes functional modelling and prototyping. Functional modelling allows for the ongoing testing of design concepts for yet-to-be-realised technological outcomes. Prototyping allows for the evaluation of the fitness for purpose of the technological outcome itself.
Through technological modelling, evidence is gathered to justify decision making within technological practice. Such modelling is crucial for the exploration of influences on the development of the proposed outcome, and for the informed prediction of the possible and probable consequences of the proposed outcome. Technological modelling is underpinned by both functional and practical reasoning. Functional reasoning focuses on 'how to make it happen' and 'how it is happening'. Practical reasoning focuses on 'should we make it happen?' and 'should it be happening?'
Decisions as a result of technological modelling may include the termination of the development in the short or long term, continuation of the development as planned, changing/refining the design concept and/or the nature of the technological outcome before proceeding, or to proceed with the prototype as planned and/or accept the prototype as fit for purpose.
