Quality Rate is a metric used in manufacturing and production to measure the proportion of products that meet quality standards out of the total number of products produced. It reflects the efficiency and effectiveness of the production process in terms of producing defect-free items.

Quality Rate is calculated using the following formula:

For example, if a factory produces 1,000 units in a day and 980 of them pass quality inspections, the Quality Rate would be:

A higher Quality Rate indicates a more effective production process with fewer defects, leading to higher customer satisfaction and lower costs associated with rework and waste. Monitoring and improving the Quality Rate is essential for maintaining high production standards and competitiveness in the market.
