The development of a technological outcome (product or system) or any other outcome of technological practice (concepts, plans, models etc) involves the generation of design ideas and the refinement of potential outcomes through ongoing experimentation, analysis, testing, and evaluation against the specifications of the brief. Initial trialing of ideas, both conceptually and practically, should allow for the identification of knowledge and skill required for enhancement of both the practice and the outcome. Outcome development is enhanced through the effective presentation of conceptual ideas to stakeholders and analysis of their feedback. Exploration of materials in terms of functionality and aesthetic impact and implications should be undertaken as extensively as possible in order to interrogate designs and planning as fully as practicable prior to the selection of materials and the development of any final outcome.
Outcomes, and the practice undertaken to develop them, should be critically evaluated from a range of perspectives to ensure 'fitness for purpose' is seen in its broadest sense. Testing of mockups, and evaluation of models and prototypes, and their trialing in intended or simulated locations, should be ongoing with feedback sought from stakeholders regularly.
