TAIS is significant for several obvious reasons. One is historical. The work was published shortly after the introduction of the concept of Software Engineering and before the emergence of OOP, Design Patterns, and other currents which came to represent the mainstream of of systems analysis and design practice. Since Langefors actually developed his system during the even earlier period and thus to some extent its time and space complexity concerns seem archaic. The approach was developed over some time before the mid-1970s and so reflects a relatively low-level focus that seems quaint in a modern context. However the material culminating in the chapter on System Design Computation is of enduring value. I believe Langefors died a few years before the turn of the century and there was both a final work by him, related work by colleagues in ''Regnecentralen'' and other organizations, and related work from unrelated sources.

The work would probably not be acceptable in the computer science community of today as it exposits a mathematical treatment of systems analysis without actually providing details of that math. This doesn't detract from its intrinsic and is even an advantage as it doesn't offer anything to undo in basing on operational elements now existing which can provide same.
