Below are five methods to reduce a supplier base:

1. Spend Analysis: Reviewing cataloged business spent data, organizations will identify inefficiencies, root out unnecessary costs, remove waste and redundancies, and find gaps within the supply chain and its vendors to make changes that will ultimately reduce costs (Sinnett, 2019).
2. Contingent Supplier: To prevent supply chain disruptions and delays, organizations should have a backup supplier as a fail-safe. The organization should carry out the necessary checks as they would with the primary supplier. Theoretically, an agreement would be struck to keep some critical items on the shelf for a time to alleviate availability concerns (Minett, 2022). This vendor would be aware they are an emergency standby option.
3. Quality Based Reduction: In this method specific thresholds are put in place on the quality of product or services supplied by the supplier. These thresholds are highly measureable and quantifiable. The goods or services supplier by the supplier are measured against these thresholds over a predetermined amount of time and suppliers whose products or services fail to meet these thresholds are eliminated from the supplier base (Linsley, n.d.).
4. Supplier Visibility: Supplier visibility enables an organization to track the progress of orders and response times in the event of any issues. On a higher note, organizations can obtain financial reports during the material procurement process to see if their suppliers are financially stable enough to support both current and future projects (Minett, 2022).
5. Cost Based Reduction: Using financial considerations, the products or services of the supplier must meet a minimum required standard (Minett, 2022). To achieve this, the average cost of supplies from a supplier is a particular category is calculated over a predefined time. The list of suppliers is then filtered to remove any suppliers which do not meet the predefined standard in quality. The remaining suppliers are arranged in the increasing order of cost and only the top suppliers are retained.
