SURE-QUAL- index used to measure the relationship quality of two groups. It’s may be Farmer and processor (Schulze, Wocken & Spiller, 2006.), farmer and intermediaries.
“The resulting Supplier Relationship Quality Index (“SURE-QUAL- index”) represents the overall assessment of an agribusiness processor through the farmer-suppliers.” (Schulze, Wocken & Spiller, 2006.)
SUREQUAL index measures the Relationship Quality of the farmer and supplier using trust, commitment, and satisfaction.
I want to know that is, how we decide the ranges of the relationship quality (Excellent, Medium, and Low), how we decided to that values which are represent the ranges?
