Entrepreneurial Orientation: Reviewing Three Papers and Implications for Further Theoretical and Methodological Development Dennis P. Slevin Siri A. Terjesen We evaluate the contributions to entrepreneurial orientation (EO) in three articles: Wales, Monsen, and McKelvie; Wiklund and Shepherd; and Morris, Webb, and Franklin, commenting on key findings and their implications for further development of EO. We outline the potential for a multiplicative construct of EO and future directions for research in the field of inter- national entrepreneurship: cross-border internationalizing firms and comparative studies. Introduction Three decades since its conceptualization, entrepreneurial orientation (EO) is a central component of entrepreneurship and strategy research. Seminal contributions by Miller (1983; Miller & Friesen, 1982), Covin and Slevin (1989, 1991), and Lumpkin and Dess (1996) have each accumulated over 1,000 citations. 1 The breadth and depth of EO scholarship enables meta-analyses; however, many key knowledge gaps remain (Rauch, Wiklund, Lumpkin, & Frese, 2009). We thank the special issue editors, Jeff Covin and Tom Lumpkin, for inviting us to discuss the papers and future directions for EO research. This commentary reviews three papers that enhance our understanding of EO: Wales, Monsen, and McKelvie (2011), Wiklund and Shepherd (2011), and Morris, Webb, and Franklin (2011).
