Is People-Structure-Tasks-Technology Matrix Outdated?

The paper investigates whether the classical socio-technical matrix that differentiate 4 quadrants of social-technical system: people, structure, tasks and technology can still be useful for practical purposes. The paper gives a positive answer on the question, provided that the level of abstraction in defining these four quadrants is increased to deal with culture, type of structure, methods (techniques) and type of technology, as well as the idea of joint optimization is substituted with the idea of alignment. The paper presents some examples where the concept of the augment matrix has been used.
