Ma'ayan is a software package developed by the Israeli extension service. The package was developed under the assumption that extension has a comparative advantage in bridging the gap between farmers' need for innovative farm management practice, managerial information and software to support it. Farmers producing a wide range of products adopted Ma'ayan. In many cases the adoption process had to overcome various barriers such as: insufficient knowledge using a PC, conservatism, cost benefit considerations, etc.. This review details the results of successful implementation of Ma'ayan as a case study of adoption of a software package for farm-management.
