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) : --------------------------------------------------------------------------- SP HIPO | | |-| SADT | | | JSP/JSD | | |-| | |------| | | |------| | | | | SD (1974-78) <Yourdon> | | | |--| | | | SA (1978-79) <DeMarco> |-----| | | | | | | |--------------------------------| | | | | | | | | |-------------------| | | |--------| | | | | | | | | | | | | | | | | | | | STRADIS (1979) | | | | | | | | | | IE (1981) | | | | | SA/SD (1982-84) | | |----| | | | | | Boeing-Hatley RT | | (1984) | | | |---| | | | | | Ward-Mellor RT | | (1985-86) | | | | SSADM (1986) Hatley-Pirbhai RT (1987) --------------------------------------------------------------------------- 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. -- ====================================================================== tensu%vehka.uta.fi@uunet.uu.net * Tampere Finland Europe Login ergo sum. <> Workload is not killing - it is challenging.
