Supplier Key Performance Indicators (KPIs) are a set of measurable values that help organizations evaluate the performance and effectiveness of their suppliers. These KPIs can be divided into two categories: people-related and process-related.

People-related KPIs:

1. Employee turnover rate: The percentage of employees who leave the organization within a given period. High turnover rates can indicate issues with employee satisfaction or management.
2. Employee engagement score: A measure of how engaged employees are with their work and the organization. This can be measured through surveys or other feedback mechanisms.
3. supplier diversity index: The percentage of suppliers that are from diverse backgrounds, such as gender, race, or ethnicity.
4. supplier safety performance index: A measure of how safe suppliers' workplaces are for their employees. This can include metrics such as workplace accident rates or employee injury claims.

Process-related KPIs:

1. on-time delivery rate: The percentage of orders that are delivered to customers on or before the promised delivery date.
2. quality score: A measure of the quality of products or services provided by suppliers. This can be measured through customer complaints, returns, or other metrics.
3. total cost of ownership: A measure of the total cost of working with a supplier, including factors such as price, lead time, and quality.
4. supplier performance index: A measure of how well suppliers meet specific performance criteria, such as meeting production deadlines or maintaining consistent quality standards.
