When architects study models, miniatures or maquettes they inevitably do so using a theoretical framework that has its origins in the process of design. Such a framework is necessary because the physical and representational qualities of a model are typically insufficent to fully interpret its purpose. For example, when examining a model a determination can be made of the quality of the construction process and materials that have been used. This can suggest something about the investment that has been made in its production but this not, in itself, enough to classify or understand the model. Similarly, the degree to which a model actually resembles a completed building, either in whole or in part, can also be used to offer a determination about the purpose of the model. But without an additional body of information, the physical and representational characteristics of the model are inadequate. The theoretical framework that reforms the majority of architectural scholarship about the model is derived from an idealised understandlng of the design and procurement process for a building.
