Our final sampling frame was composed of 879 firms from both the hardware and software industries (350 and 529 firms, respectively). This focused method of sampling helped us to exclude firms irrelevant to the research context. After this, we collected data via three rounds of web-based surveys, followed by a fourth round consisting of a field survey. To increase the response rate, we actively used social networking sites, sending them emails to introduce the purpose of our research and ask them to complete the web survey.
