This chapter seeks to provide criteria for selecting successful GI products. The discussion makes the point that not all origin based products have the potential to benefit equally from GI development and protection. The authors' experience in selecting products for inclusion in the research project on which this book is based, but also in the subsequent process of designing industry specific GI strategies for two South African GIs (Rooibos and Karoo lamb), has shown that it is possible to identify certain factors which are predictive of an origin product and/or industry's ability to benefit from GI protection. Drawing on this experience as well as the international literature this chapter seeks to develop guidelines which can be used in Southern countries for evaluating whether a product has the potential to develop into a successful GI and to harness the potential associated with GI protection.
