3.2 Step 2: Questionnaire Survey Design and Execution
In software engineering, the empirical approaches that are used most frequently are case studies, questionnaire surveys, and experimental analyses [28]. To obtain industry practitioners’ opinions on SLR findings, this study used Google Docs to create an online questionnaire [27], identifying security risks and associated practices to mitigate these risks. Collecting data directly from industry experts in different parts of the world is hard. Therefore, we employed a non-methodical approach to data collection through a web-based questionnaire survey. Other software engineering researchers used the same data collection strategy [29-33]. Methods used in the questionnaire survey were as follows:
