Really complicated problems

Abstract

These two methods have many similarities, particularly at the ideological level. For example, they provide more ‘front end’ stages with no prejudgements than some other methodologies, which attempt to ensure we are solving the right problem. There are also some differences. The aim of this short section is to summarize and extend the comparisons made earlier, concentrating particularly on the differences. This should enable you to decide whether these are significant enough to preclude the use of one or another technique under certain circumstances, but perhaps more importantly this section shows how a synthesis of the two methodologies can be usefully achieved.
