“…As case study gained popularity as a qualitative research method in the 1980's and beyond, many researchers attempted to put consistent standards around its design so that the academic world would accept its validity. Most researchers agreed in general with Yin, Stake, and Merriam's perspectives that case studies focus on a specific event, bound by criteria such as time and space (Easton, 2007;Hughes & McDonagh, 2017;Noor, 2008;Poulis, Poulis, & Playkoyiannaki, 2013;Tsang, 2013;Welch et al, 2009). Moreover, they also assented that case study should be rooted in a research paradigm, shaped by a framework, and outline the context of the case (Easton, 2007;Hughes & McDonagh, 2017;Noor, 2008;Poulis et al, 2013;Tsang, 2013;Welch et al, 2009).…”
