This empirical study attempts to verify non-linearity relationships among three quality dimensions and user satisfaction from the DeLone and McLean IS Success Model. We use survey data from Agriculture integrated eXcellence systems (AgriX) users and a multiple regression analysis with dummy variables to analyze separately high and low performance groups. Results from the analysis suggest that influences of qualities on satisfaction are non-linear. The impact of qualities is not symmetric and grouped into three distinct types- basic factors, performance factors, and excitement factors.
