This study consists of two parts. Firstly, multiple case studies were in-depth interviewed in order to be used in
conjunction with the SEM model (from the work of Khemavuk and Hasan, 2010). Lastly, the SEM model was validated
using data from an international company in Australia. Campbell and Fiske (1959) started using triangulation in social
sciences. They recommend that more than one method should be used in the validation process to ensure that the
variance reflected the trait not the method. Later, Denzin (1978) discusses methods of triangulation by outlining four
types of triangulation: data triangulation, investigator triangulation, theory triangulation and methodological
triangulation.
