In the daily work of textiles, I believe that many people will often use a lot of quality indicators, but the detailed definition of these indicators, many people are confused, or can not organize language to express. Whether you are a veteran who has spent years in the textile industry or a newcomer to the textile industry, the next “dry goods†you can definitely collect! Definition: Waste rate refers to the proportion of the total cost of waste materials in the total production cost, or the proportion of the total amount of waste products in the total production volume of the product. Purpose: The waste rate can be used as a measure of the outcome to determine if the process is part of the production and assembly of the part. Formula: scrap rate = (material cost of scrap / total production cost) × 100% Or = (total scrap quantity/product total production quantity) × 100% Terminology: 1 Waste Material Cost: The value of the material used for scrap. 2 Total production cost: The sum of the labor, materials, and factory burden (water, electricity, etc.). Note: The data source for calculating the scrap rate is the direct company's financial system. If the company’s financial system cannot separate the value of waste materials from labor and burden, it should coordinate with related departments as soon as possible. 2 rework Definition: The proportion of time spent on rework of unqualified products to total hours of work, or the proportion of rework/repair of defective goods to total production. Purpose: The rework rate can be used as a measure of the outcome to highlight those operations that need improvement in the first quality. Formula: Rework rate = (Rework hours / total production labor hours) × 100% Or = (total number of rework (rework) products/total production quantity) × 100% Terminology: 1 Rework hours: It refers to the time it takes to reprocess, sort, and repair parts that will become scrap. These times can be used on work products, finished products and purchased parts or materials. Rework time includes such things as repairs, repackaging, sorting, additional inspection activities, and containment. Rework time includes internal or external activities and should include direct time plus direct time during overtime hours. 2 Total production labor hours: Total work hours for direct/production workers (including direct time plus direct time during overtime hours). Note: Occasional inspections of direct workers should not be considered rework. Any product that re-enters the production process should be considered reworked and this part will be determined based on the reworked product. 3 product inspection rate Definition: The ratio of the qualified quantity of the products in the warehouse inspection to the total quantity of the warehouse inspection. Purpose: Product acceptance rate can be used as a process metric to measure the quality level of the entire production process. Formula: product acceptance rate of inspection = (qualified quantity of product inspection / total quantity of inspection) × 100% 4 million unqualified items Definition: The number of rejected parts per million is customer return rate, product defect rate. This refers to the ratio of the number of rejected/rejected customers or the number of non-conforming products per million products to the total shipments or total production total. Purpose: This percentage can be used as a measure of the outcome to fully demonstrate the impact of product dissatisfaction. This indicator helps manufacturers focus their efforts on problem solving. Formula: Customer Return Rate = Number of Returned Items / Number of Shipments Total Product Quantity * 1,000,000 or Product Bad Rate = Total Number of Nonconformities / Total Product Quantity * 1,000,000. 5 quality accidents Definition: Quality accident refers to the number of production pauses due to product failure each year. The occurrence of a quality accident will result in the company stopping the shipment, stopping the production, or requesting the correction of the manufactured product. Purpose: Quality Accidents can be used as a measure of the overall outcome, reflecting the dissatisfaction with the product caused by the number of quality accidents in the company. This indicator helps the company to focus on solving problems. Formula: Quality Accident = factory production pauses caused by company-defined quality accidents each year 6 inspection pass rate or process pass rate Definition: The inspection qualification rate or process qualification rate is the ratio of one qualified product quantity in the production process to the total product quantity. Purpose: The inspection qualification rate or process qualification rate can be used as a process metric to determine the quality level of the production process. Formula: inspection qualified rate or process qualification rate = (process qualified number / total product quantity) × 100% 7 customer inspection pass rate Definition: The customer's one-time pass rate refers to the delivered product, which is the proportion of the total quantity of all delivered products received by the customer once passed the inspection. Purpose: To use as a result measure to measure the quality level of the finished product. Formula: customer pass rate of one pass% (the number of qualified customers receiving one pass / total number of delivered products) × 100% 8 feed inspection pass rate Definition: Feed inspection pass rate is also called incoming inspection pass rate. It refers to the ratio of the qualified amount of feed inspection to the total number of incoming inspections within a certain period of time. Purpose: Used as a result measure to monitor supplier supply quality levels. Formula: Feed Inspection Pass Rate % = (Incoming Feed Inspection Passed Quantity / Feed Inspection Total Number) × 100% 9 quality cost Definition: Quality cost refers to the cost of failure or loss over a period of time. Purpose: Quality cost can be used as a result measure to reflect the integrated results of the company's operational effectiveness of the quality management system. formula: 1 Quality cost = internal failure (loss) cost + external failure (loss) cost 2 Internal failure (loss) cost = scrap loss fee + rework or repair loss fee 3 External fault (loss) cost = customer return loss fee + product liability fee + complaint fee 4 Quality cost as sales ratio = (Quality cost/sales) × 100% Terminology: 1 Internal failure (loss) costs: Losses caused by the product failing to meet quality requirements before delivery; 2 External fault (loss) costs: Losses caused by the product failing to meet quality requirements after delivery; 3 Scrap loss fee: The cost of lost of finished products, semi-finished products, work-in-process products that cannot meet quality requirements and cannot be repaired or economically worthwhile to repair; 4 Loss of rework or repair costs: fees paid for the repair of nonconforming products to meet quality requirements or anticipated use requirements; 5 customer return loss fees: customer return loss of the waste product; Product Liability Fees: related compensation losses caused by product quality failures; Slim Fit Pants,Slim Fit Casual Pants,Men'S Stretch Trousers Slim Fit,Pants Slim Fit Classic Color Shaoxing Tongbang Textile Co.,Ltd. , https://www.sxtongbangtextiles.com
