Mapping the changes in management science: A review of ‘soft’ OR/MS articles published in Omega (1973–2008)

The paper proposes a framework to map the development of management science (MS) and uses it to survey the MS literature published in Omega, the International Journal of Management Science. The management science discourse over the last 35 years is mapped in four paradigms: (1) optimisation/normative; (2) interpretative/learning; (3) critical; and (4) a post-modern management science approach. Using a set of keywords and authors’ names associated with the main features of each MS discourse, articles published between 1973 and 2008 are grouped. Results seem to suggest that Omega, a US-based journal, has been mainly developing publications under the optimisation paradigm; only very few papers adhering to the interpretative/learning and critical paradigms have been given space in Omega. The handful of papers from the interpretative paradigm are seen as attempts of UK-based academics to open some space for ‘soft’ operational research (OR) or ‘problem structuring methods’ in a positivistic outlook that seems to pervade US management science practice. Results of the survey and features of MS literature published in Omega are discussed. The paper aims to raise awareness amongst management scientist, systems and operational researchers of the differences between the MS/OR practice in both countries.
