3. Methodology
The three types of Delphi technique’s mentioned above in application can be defined as follows. The first type of Delphi is called the classical Delphi and is characterised by Skulmoski et al., (2007, P.2) with the following features:
a. Anonymity of participants; allows free expression of opinions and feedback is motivated by individual experiences rather than expectations from industry groups.
b. Iteration; allows the participants to refine their views in comparison with the panellists without losing credibility.
c. Feedback; Informs the participants of the other participants perspectives thereby providing an opportunity for Delphi participants to clarify and change their views (Skulmoski, Hartman, and Krahn, 2007, P.3).
d. Statistical …show more content…

The Second type of Delphi is called a Policy Delphi which intends to achieve stability in responses among those whose expert opinions have considerable impact on current industry trends, while building on policy alternatives using a system of public discussion. Nonetheless, the purpose of the present study could be considered instrumental when developing policies within government departments, agencies, institutions, and also within large companies or organisations; by promoting participation from opposing opinions especially with stakeholders. Similar to the “Classical” Delphi a “Policy” Delphi is characterised by selective anonymity; iteration, controlled feedback, polarised group response and structured conflict (Hanafin, 2004, P.6). The third type of Delphi is the “Decision” Delphi which is mostly applied when conducting social science investigations. Besides, this enquiry system is centred on a group of decision makers rather than from ad hoc decisions of a small number of people (ibid). Moreover, the construction of a panel in a “Decision” Delphi technique rely on the opinion of a cluster of decision makers rather than a collection of people …show more content…

Similarly, the theoretical frameworks identified pertaining to the study area were demand variability, vertical integration, and process orientation. In addition, Nigeria as a major crude oil exporter amongst others in the African continent has predominately depended on the resource base of multinational oil companies (MNOC’s) to sustain efficiency in export distribution. Moreover, notable audits on distribution efficiency have not been well documented by Nigerian National Petroleum Company (NNPC), and oil interest groups. Therefore, the gap in between the distribution efficiencies found in the Persian Gulf in comparison with Nigerian oil distribution has encouraged further investigations into root causes by applying a Delphi technique to gather a consensus of opinions relying on the theoretical implications mentioned above.
Initially, research questions were developed to further understand underlying industry observations or heuristics established from planning the theoretical framework. In addition, the literature review also assisted in determining key issues relevant to oil exportation from Nigerian upstream ports and Jetties, incorporating the observed and investigated theoretical gaps. Furthermore, these theoretical gaps were utilized to develop the main research question;
