Sample SizeOne of the key tasks in qualitative research, in addition to selecting a research topic, is to produce credible research by obtaining an appropriate sample. This is to ensure that there are sufficient facts for possible research and justification of qualitative research conclusions (Marshall, Cardon, Poddar, & Fontenot, 2013). According to Marshall, Cardon, Poddar, and Fontenot (2013), qualitative researchers rarely justify the sample size of qualitative interviews. Furthermore, available qualitative research methodologies provide few concrete guidelines for estimating appropriate sample sizes. This is particularly evident in information systems (IS) research studies (Marshall, Cardon, Poddar, & Fontenot, 2013), despite the plethora of existing information systems (IS) qualitative research information. Indeed, according to Sarker, Xiao, and Beaulieu (2013), until the mid-1990s, a significant number of traditional IS scholars, particularly North American and Asian ones, believed that research was quantitative and that studies that did not use accepted quantitative methods methods have been excluded from the very definition of research. Qualitative research uses purposive sampling instead of taking a random sample and addressing the assumptions of statistical analysis techniques. Hanson, Balmer, and Giardino (2011) noted that research chooses a sample of participants or documents to achieve a particular purpose and obtain the information most applicable to the research question. As the study progresses, the qualitative researcher can identify additional participants or documents that may confirm or challenge emerging insights in an effort to build deeper understanding and clarify themes (Hanson, Balmer, &...... half of the paper... ...new qualitative interviews in research.
