# What is an acceptable ppm for manufacturing?

**PPM**defectives rate of 10,000 means the defect rate is less than 1%. However; with the passage of time, the expectations increased to 1,000

**PPM**and now, the expected

**PPM**rate, especially in the

**manufacturing**industry across the globe, is around 75

**PPM**.

Similarly, what is ppm in automotive industry?

For all who don't know, “**PPM**” means “**parts per million**”. **PPM** is in the **automotive industry** an established KPI (Key Performance Indicator) to measure your quality performance. 1PPM means that you got 1 defect within 1 million parts produced.

**DPPM**= Defective

**Parts per Million**; A measure of quality performance. One

**DPPM**means one (defect or event)

**in a**million or 1/1,000,000. 0.025 X 1,000,000 = 25,000

**PPM**.

Also to know is, how do you calculate ppm quality?

**PPM** (**Parts per million**) is a measurement used by many customers to **measure quality** performance. To **calculate**: For example, if you had 25 pieces defective in a shipment of 1,000 pieces. 25/1000= . 025 or 2.5% defective. .

Defects per million opportunities (**DPMO**) **Six**-**Sigma** is determined by evaluating the **DPMO**, Multiply the DPO by one million. Process **Sigma** Once you have determined the **DPMO**, you can now use a **Six Sigma** table to find the process **sigma**. You will look for the number closest to 33,333 under defects per 1,000,000.
