“…Some indicate the overall organization or firm as the relevant unit of analysis (e.g., Learned et al, 1965), while others do not. Some refer to the importance of organizational performance or success (Bowman et al, 2002;Rumelt et al, 1994;Schendel and Hofer, 1979), some to external environments (e.g., Bracker, 1980;Jemison, 1981), some to internal resources (e.g., Bracker, 1980;Jemison, 1981), some to strategy implementation (Van Cauwenbergh and Cool, 1982), and some refer to none of these (e.g. Smircich and Stubbart, 1985).…”
