Engineering is largely concerned with models and modelling. Models provide a context in which decisions are made. Here, the modelling process is considered in a general sense and then the relationship with engineering models is developed. For understanding, a first step is to differentiate and categorise. Thus, 10 types of engineering models are proposed and their purposes with respect to professional decision-making are discussed. The role of models in engineering failures is also considered.
