**Step 5: Assess suppliers directly**

A buyer can compare the scores of different suppliers for the same order and select one based on the evaluation score. It may be possible that supplier does not qualify at this time for further purchase consideration. Purchaser should have minimum acceptable performance necessities that suppliers must assure before they can become part of the supply base [3].

#### **Step 6: Make selection based on evaluation results review**

The major output from this step is a proposal about whether to accept a supplier for a business. A buyer may evaluate several suppliers who might be competing for a purchaser contract. The intention of the evaluation is to qualify potential suppliers for current or future business requirements.

#### **Step 7: Review supplier performances constantly**

After selecting a supplier, the supplier must perform as per buyer requirements to fulfill their needs. The prominence shifts from the initial evaluation and selection of suppliers to continuous improvement by suppliers into their process and product to fulfill buyer requirement.

Few authors have acknowledged criteria for supplier selection, such as the price, quality, and delivery, past supplier performance, capacity, information systems, service, and geographic location, among others [4–6]. These criteria are a key issue in the supplier measurement process since it dealings the performance of the suppliers.

#### **1.2 Methodology**

In most of the research which is based on supplier selection and evaluation, authors opined that the purchasing organizations use different approaches for evaluating and selecting supplier as per their requirements because of no best way is there.

Supplier selection is based on a relative assessment using an exploratory case study approach which is generally used in most of the OEMs (Original Equipment Manufacturers).
