“…According to Rikkonen et al (2006) suggested that the Delphi technique is a method for the structuring of a group communication process so that the process is effective in allowing a group of individuals, as a whole, to deal with a complex problem (Mohorjy and Aburizaiza, 1997;Kuusi, 1999;Rowe, 2001;Linstone and Turoff, 2002;Tapio, 2002). Brill et al (2006) describe Delphi as a particularly good research method for deriving consensus among a group of individuals having expertise on a particular topic where information sought is subjective and where participants are separated by physical distance (Linstone and Turoff, 1975).…”

Purpose -The purpose of this paper is to provide project management (PM) students with an example of the Delphi research approach that was applied to a recent doctoral research thesis. The objective is to provide both a description of the approach and an explanation of how it was successfully applied so that researchers in PM may become more aware and expand their perceptions of methodological options available to them. Design/methodology/approach -The paper sets out a literature review of the Delphi approach and explains this research method as it was experienced as a research tool. The paper also provides reflection on the experience of being a researcher undertaking a doctoral study. Findings -The Delphi approach is one of many that may be selected for researching PM issues and problems. It is appropriate for researching complex issues where larger scale quantitative "hard data" fails to unearth richness in tacit knowledge to help the research understand subtle expert opinion. It does not offer the rigor of clinical testing or quantitative analysis, but it provides a scientific methodology that is well suited to issues that require the insights of subject matter experts.

“…The users of the Delphi technique aim to explore alternative future images, possibilities, their probabilities of occurrence, and their desirability by tapping the expertise of respondents. Linstone and Turoff (1975, p.3) characterize Delphi as a method for structuring a group communication process in such a way that the process is effective in allowing a group of individuals, as a whole, to deal with a complex problem (see also Sackman 1975, Mohorjy and Aburizaiza 1997, Kuusi 1999, Rowe and Wright 2001, Tapio 2003. The Delphi method consists of experts' judgement by means of successive iterations of a given questionnaire, to show convergence of opinions and to identify dissent or non-convergence.…”

“…In the following Figure 2, four categories are organised based on the standard deviation of importance (y-axis) and the importance rating (x-axis) by the panel (see e.g. Mohorjy and Aburizaiza 1997). The categories presents issues that (A) indicates less important but divergent topics, (B) indicates key uncertainties and "the flesh and bones" for scenarios, (C) indicates non-significant questions and (D) refers to basic premises according to the panel.…”

This article presents alternative scenarios for future agriculture in Finland up to 2025. These scenarios are the results of a large Delphi study carried out among Finnish agri-food sector stakeholders. The Delphi panel members gave their future view on desirable and probable futures. From these two dimensions, three scenarios were elaborated through the future images -the subjective future path and the importance analysis. The scenarios represent a technology optimistic "day-dream agriculture", a probable future as "industrialised agriculture" and an undesirable future path as "drifting agriculture". Two mini-scenarios are also presented. They are based on a discontinuity event as an unexpected impact of climate change and an analogy event as an ecological breakdown due to the expansive animal disease epidemics. In both mini-scenarios, the directions of storylines are dramatically changed. The scenarios support strategic planning introducing not only one forecast but alternative outcomes as a basis for future strategy and decisions. In this study the scenarios were constructed to address the opportunities as a desired vision and also the threats as to an undesirable future in the agricultural sector. These results bring to the table a Finnish agri-food expert community view of the future directions of relevant key issues in the agricultural policy agenda.

-Differentiated quality and respect for the environment seem to be linked implicitly, but there is no demonstration of this concept for pig production. Pig production takes on different forms. Conventional pig production occurs side by side with some productions of "differentiated qualities" that are encouraged by the European Union as well as by nations. At the same time, the EU and nations are imposing environmental limitations concerning, for instance, the management of nitrogen and respect for neighbours. Here, we compared environmental impacts of 3 types of production: conventional production, organic production and free-range production. We took into account the process performances of 21 farms in the Walloon Region, Belgium. We compared the global process performances by multicriteria analysis. A jury of 16 experts was questioned to assign a relative importance to the emissions of ammonia, greenhouse gases, molecular nitrogen, odour and nitrogen to effluents. We found that the highest weighting was assigned to the N content of effluents, then to odour diffusion, the emission of ammonia, the emissions of greenhouse gas and finally, the emission of molecular nitrogen got a weak weighting. Our results showed that the relative ordering obtained was: (1) free-range production, (2) organic production and (3) conventional production. Nevertheless, within every sample a significant variability in the performances was observed. The same method applied within every sample enabled the creation of sub-groups. After reordering, we found that the most effective farms of every system of production were classified as top of the class. Thus, our original approach showed that on average the production of differentiated qualities was more environmentally effective than the conventional production. However, the variability of the performances within a system of production was high and it was quite possible for the conventional farms to reach results comparable with those of the best organic and free-range operations. differentiated quality / organic farming / free-range farming / nitrate Directive / ammoniac / odour / Electra III
