The systems stance

An engineer can be greatly helped in dealing with complex and unusual systems by taking a specific attitude to the world of reality: The Systems Stance. It involves an attitude of personal engagement and in which one relates to almost all reality by means of models. Of the many forms of model, the most important distinction is between generic and specific models. Modelling is discussed generally including the discipline required by a set of system modelling principles. A more detailed discussion on systems and systems models follows, where model definition is seen as a process marked by increasing confidence or decreasing uncertainty. The advantages and limitations of subjective approaches are stressed, together with a need for care and a sound ethical foundation. Specific areas of interest are: the place of temporal issues; questions of value emphasising quality and a system aesthetic; and the relation of the systems stance to uncertainty and surprise.
