An accelerated scientific, engineering, and industrial progress in information technologies has fostered the
deployment of Complex Information Technology (highly dependent) Organizational Systems (CITOS).
The benefits have been so strong that CITOS have proliferated in a variety of large and midsized organizations to support various generic intra-organizational processes and inter-organizational activities.
But their systems engineering, management, and research complexity have been substantially raised in
the last decade, and the CITOS realization is presenting new technical, organizational, management,
and research challenges. This chapter uses a conceptual research method to review the engineering,
management, and research complexity issues raised for CITOS, and develop the rationality of the following propositions: P1: a plausible response to cope with CITOS is an interdisciplinary engineering
and management body of knowledge; and P2: such a realization is plausible through the incorporation
of foundations, principles, methods, tools, and best practices from the systems approach by way of
systems engineering and software engineering disciplines. Discussion of first benefits, critical barriers,
and effectiveness measures to reach this academic proposal are presented.
