Evaluation of Alternatives:

In a manufacturing organisation the production research and purchasing people join hands together. They evaluate products and sources of supply to help purchasing department to identify the right product. The evaluation is done for such factors as product performance, price and supplier's ability to meet delivery schedules. The supplier must provide a consistency in quality.

Purchasing Decision:

The buyer bases his decision on evaluation outcome. He decides on a particular brand and supplier before he negotiates the contract. The contract is bound to have many details because the large sums are usually involved. Also many people are involved before the final contract is signed.

Post - Purchase Behaviour:

The buyer continues to evaluate the performance of the product and the selected supplier. This is done to ensure that the buyer's expectations are adequately met. Any future dealings with the supplier will be affected by the results of post-purchase evaluation. In the case of Express Kenya Ltd., Mercedes benz proved to be better than a BMW in terms of product reliability and better performance.
