This research focuses on one of the main steps in outsourcing, supplier
evaluation and selection. The main contributions of this research were twofold.
First, best practices in the supplier’s value stream were identified that directly or
indirectly impact a supplier’s quality and delivery. Second, a comprehensive
supplier evaluation and selection model was developed based on the value
stream concept to minimize the risk associated with two very critical supplierselection factors, quality and on-time delivery.

A survey was conducted to identify best practices. The outcome of the survey
was used to develop a computer based supplier evaluation model, which could
be used in conjunction with other existing supplier selection factors, such as price and others, to select suppliers.
