'''Theoretical Analysis of Information Systems'''¹ is a published approach to mathematical modeling of a general enterprise information system based on systems theory and algebra. Its results are basic and startling only to the degree in which something like what the book does has not become an element of common IS practice. | '''Theoretical Analysis of Information Systems'''¹ is a published approach to mathematical modeling of a general enterprise information system based on systems theory and algebra.

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. | |||

TAIS is significant for several 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. | |||
