Anyone could be Never heard of that one, but Ward/Mellor was _very_ popular (in the UK anyway) and also combined control and data flow very easily (still my favourite notation even after a while using UML). I understand they were the first to combine STD into DFDs. Their books are now amazingly cheap (compared to 10 years ago!) "Structured Development for Real-Time Systems : Essential Modeling Techniques" and "Structured Development for Real-Time Systems : Implementation Modeling Techniques" I seem to remember a third book but can't find it on amazon... Reading these should be mandatory for all s/w engineers even if they never use the method or notations ever!!! :-)
