12: Example of an activity model of an Order Validation System (see Stowell and West, 1994, p. 87) directly from some appreciation of the activities of any named system (for example, one identified in a Black Box diagram or a systems map). The activities themselves describe purposeful activity, each activity is doing something and as such each description of an activity begins with a verb. The relationship between each activity is a logical one rather than an incremental one. If the activities are numbered then it should be taken as an address rather than a representation of the order of execution of a set of actions.
The so-called ‘Credit Crunch’ of the early 21st century had multiple causes. These included attempts to ‘eliminate risk’ through a complicated formula (which apparently few fully understood) applied by financial institutions to dubious credit transactions which unsurprisingly failed. Some analysts blamed collateralization, others access to easy money and the driver of large bonus rewards within the banking sector. For some it was the mispricing of risk in mortgagebacked securities and for others lax regulation.
9: Examples of ‘correct’ and ‘incorrect’ diagrams M ode l s and M ode l l ing 31 In the above diagram there is a mixture in the level of detail which will lead to problems. If the input and output data have not been consistent across the descriptions of the different sub-systems then it will prove difficult to find corresponding outputs and inputs. The problem of maintaining a consistent level of detail across the analysis is one which is relevant to all systems diagrams and little advice can be given about how to avoid falling into this trap.
