(a) One of the tasks that Jennifer really enjoyed, while she was working in the private sector, was to determine the 'right' procurement strategy for each supplier. In her company, Kraljic's portfolio analysis and supplier preferencing were commonly used tools to determine the procurement strategy for suppliers. Analyse how Kraljic's portfolio analysis and supplier preferencing can be used to determine the procurement strategy for each supplier.

(b) It is Jennifer's last day at the current workplace. Jennifer is having a meeting with Jake who is the successor to her at the company. Jake has some trouble to understand how suppliers can be evaluated on cost/price. Apart from just looking at the price quoted by the supplier, Jake is not sure what else should be considered in evaluating suppliers on price. Appraise how suppliers should be evaluated on cost/price according to Carter's 10 C model.
