Specifically, financial performance was measured in terms of ROI, ROS and market share, in accordance with studies such as Ward et al (1994), Vickery et al (1997), Papke-Shields and Malhotra (2001), Narasimhan and Jayaram (1998), Curkovic et al (2000) and Zhao et al (2006); Petkova and Dam, forthcoming). Each type of performance was measured in a comparison with each company's main competitors on Likert scales ranging from 1 for "much worse" to 5 for "much better".…”
