Rich pictures are usually, but not exclusively, a mixture of text and graphics and are intended to give an easily intelligible image of the organisation and the major issues involved. 3 Root definitions Root definitions are concise textual definitions that express the nature of the systems relevant to exploring the problem situation. These textual definitions inform the iterative development of a subsequent 'conceptual model' of the overall system. Primary task definitions aim to be a neutral account of what is necessary for the organisation to fulfil its primary role, sometimes from a mission statement, charter or official description of the organisation's activity. Another approach is to seek agreement amongst the problem owners as to what the primary-task root definition is.
Issue based definitions frequently look at part of the system only and focus on key problem areas.
Describing the transformation and worldview are essential for the construction of the conceptual model. Different groups will have different world views. It is important to highlight any conflict between worldviews as these are likely to manifest themselves as current or future problems for the organisation in question. 7 Comparison It is important to note that the conceptual model produced is a theoretical construct - it does not represent the existing or potential structure of the organisation. A process of comparison or testing is required to link the conceptual model back to the real world.
