“…One long standing criticism of the technique is the lack of a standardized process, and therefore generalizability, due mostly to the variety of problem types to which it has been applied (Linstone and Turoff, 1975;Sackman, 1975). For example, Delphi problem solving has been applied to natural resource issues such as forest biodiversity (Kangas et al, 1998) and sustainability (Mendoza and Prabhu, 2000), heritage tourism (Garrod and Fyall, 2000), environmental disputes (Miller and Cuff, 1986) and forecasting (Ying and Kung, 2000), National Park selection in Taiwan (Kuo and Yu, 1999) and aquatic habitat selection in Lake Ontario (Bush and Lary, 1996). Generalizability, however, is only an issue for applications such as forecasting, and not usually a serious deterrent (Rowe et al, 1991;Ono, 1994).…”
