Description
Pioneer of the ISDOS Project, Teichroew led a pioneering team which attempted to design and implement the Problem Statement Language (PSL) and Problem Statement Analyser (PSA) as a way of automating the delivery of Information Systems, commencing in the 1960s well ahead of other such ventures.
The work was taken up by Bodart in Belgium and Richard Welke in the US and had an important influence on the notion of CASE tools.
