Based on the literature review (as summarized in Section II), a structured close-ended interview questionnaire was developed. This questionnaire contains nine questions related to five main elements and their underlying characteristics: (1) agility; (2) people, (3) process, (4) product; and (5) tool. The structured interview questionnaire was used to capture research participants' response via face-to-face and Skype interviews. Participants from both research and industry organizations were invited via professional and research network and also through LinkedIn social media network. They included software consultants, coaches, managers, research scientists and developers. A total of 46 interviews were completed and included in this study. The interviewees had worked in a range of organizations from medium to large. Of the 46 interviewees, 24 were in industry and 22 were researchers.
