As shown in Fig. 1, the first stage of the research
was doing an extensive literature on the subject studied
by computer and manual methods. In addition, several
discussions with the academic supervisor, colleagues
and professional staff in selected organizations were
also conducted to extract valuable information in order
to construct a framework for this research. Opinions
from professional staff and documents from selected
companies were useful in gaining an early
understanding of the topics that needed to be explored.
This was followed by the formulation of a theoretical
framework which formed a structure for the study. A
set of research questions to be used in interviews was
later constructed
