The 1983 study by M. Lynne Markus, “Power, Politics, and MIS Implementation,” is a classic in the study of information technology in organizations. The web version of the Social Science Citation Index shows that over 200 other published studies have cited Markus’ classic since 1993 (the earliest year covered by the web version of the SSCI). Furthermore, its universal appeal is evident in its being regarded as an exemplar of not only positivist research (Lee 1989), but also interpretive research (Walsham 1993).
