[comp.software-eng] evolution of Structured Analysis ?

tensu@vehka.uta.fi (Tero Ahtee) (06/06/90)

Hi all you in the nets !

I'm trying to make a list of structured analysis and design methods and
methodologies, in chronological order. For example, first was structured 
programming (SP), then structured design (SD), and then structured analysis 
(SA). 

Now I'm a bit confused about when did Tom DeMarco publish his SASS-method 
(Structured Analysis and System Specification), was it 1978 or 1979 ??
Is that method the one, which is always called DeMarco's Structured Analysis ?

Did Gane and Sarson first develop a method called SSA (Structured Systems 
Analysis) in 1977 or 1978 ? I know, that this SSA is developed further to 
STRADIS (Structured Analysis, Design and Implementation of Information 
Systems) by Gane and Sarson. Is the 'Gane-Sarson structured analysis' the 
same as STRADIS (or SSA) ?? 

There are also some books ; 
* McMenamin and Palmer, Essential Systems Analysis
* Orr, Structured Systems Development
Are these independent methods ? Some persons here in Finland think that 
the names of these books are also methods. I haven't heard about methods
called 'Essential Systems Analysis' or 'Structured Systems Development'.
Would someone tell me what is the truth ? 

Here follows an evolution of structured analysis methods (my opinion) :

I have understood that Yourdon's new YSM is almost the same as SA/SD-method.
Am I right ? 

Are there any other SA- or SD-methods, that are well known ? Are there errors
in my chart ? Please let me know.
