Total systems intervention and human inquiry: The search for a common ground

Total Systems Intervention (TSI) is an approach to intervening in problem situations which has much to offer where complex interacting issues need to be addressed by the complementary use of intervention methodologies. That such an approach has much in common with Action Research (AR) has been recognized, with much recent effort being devoted to the relationship between AR and Critical Systems Thinking (CST), the theoretical endeavor underpinning TSI. This paper further develops this line of debate and relates AR or Human Inquiry (HI) more directly to TSI, using an information systems intervention to enhance the study. The outcome is a demonstration of how TSI implicitly uses techniques informed from the field of Action Research, and how a more thorough synthesis of HI with TSI might serve to improve the overall intervention process.

Business Process Reengineering (BPR) Versus Outsourcing—Critical Perspectives

This article presents a case example involving the renaming of an organizational change process from BPR to outsourcing. The paper discusses the important ramifications of such a name change in that the recognition of outsourcing allowed an organizational commitment to counseling and termination advice. The paper discusses two ways of looking at the name change, one from a critical theory perspective and one from a realist perspective. It demonstrates how theory can provide useful yet markedly different interpretations of such organizational events. Critical theory operates from within what can be termed the transitive epistemological dimension, whereas critical realism tends to emphasize the importance of ontological issues. Each has important things to say about the situation and improves our understanding overall.
