Normal Accident Theory versus High Reliability Theory: A resolution and call for an open systems view of accidents

We resolve the longstanding debate between Normal Accident Theory (NAT) and High-Reliability Theory (HRT) by introducing a temporal dimension. Specifically, we explain that the two theories appear to diverge because they look at the accident phenomenon at different points of time. We, however, note that the debate’s resolution does not address the non-falsifiability problem that both NAT and HRT suffer from. Applying insights from the open systems perspective, we reframe NAT in a manner that helps the theory to address its non-falsifiability problem and factor in the role of humans in accidents. Finally, arguing that open systems theory can account for the conclusions reached by NAT and HRT, we proceed to offer pointers for future research to theoretically and empirically develop an open systems view of accidents.

Exploring excellence in leadership perceptions amongst South African managers

We apply the excellence in leadership (EIL) framework (Selvarajah, C. T., P. Duignan, C. Suppiah, T. Lane, and C. Nuttman 1995. “In Search of the ASEAN Leader: An Exploratory Study of the Dimensions that Relate to Excellence in Leadership.” Management International Review 35 (1): 29–44) to surface the implicit views on leadership excellence held by South African managers. Our attempt is informed by an understanding of ubuntu, an African world view that draws attention to the symbiotic relationship between individuals and the community they come from. In what is one of the first efforts to empirically test the influence of ubuntu in the workplace, we hypothesize that ubuntu leads South African managers to value inclusivity and impartiality. Further, we posit that managers from the earlier apartheid-era generations, having witnessed all the inequities, would put a greater premium on ubuntu-driven values than will those from the post-apartheid generation. Structural equation modelling of the data obtained through surveying 550 managers from across sectors provided mixed support for our hypotheses. Inclusive communication and impartiality in the workplace were found to be positively associated with excellence-related perceptions. The other findings however raised questions about how ubuntu exerts influence in the workplace. We make a case for more empirical work on ubuntu and discuss the implications of our work for theory and practice as they pertain to managerial development.

Reconciliation can lead to better application: A rejoinder to Perrow (2009)

In his brief commentary, Perrow raises four issues. First, he alludes to how the misuse of bureaucratic power could explain some accidents. Second, he reiterates that normal accidents occur owing to the characteristics inherent in a system, and such accidents, irrespective of whether high reliability practices are followed or not, are inevitable. Third, Perrow asserts that complexity and coupling are independent of time of operation. The time dimension’s irrelevance, he claims, ought to be apparent from his analysis of normal accidents in systems such as the air transport and chemical industry (see Perrow, 1984). Fourth, Perrow implies that High Reliability Theory (HRT) cannot explain the sub-class of accidents that Normal Accident Theory (NAT) concerns itself with. He thus makes a case for retaining NAT alongside other theories and finds little value in our reconciliation. In fact, he finds the reconciliation inappropriate because we supposedly err in implicating time. We respond to the four issues in turn.
