What are the business indicators of automobile delivery experts?

PPM, IPB, ranking, number of complaints, offline, market claim.

1.ppm: ppm, ppm. This is the most common and commonly used indicator in the automobile industry. The specific calculation formula is: (number of defective parts/total delivered parts) * 1 million. If 6,543,800 parts are added every month and the client finds 2 defects, then PPM is 2. If the number of delivered parts is small, once there is a defect, PPM is likely to exceed the standard. Many domestic automobile industries require PPM to be less than 10.

2.IPB: one billion accidents, one in a billion ... This is the method adopted by French PSA Group to replace PPM in recent two years. The specific calculation formula is: (number of complaints/total number of deliveries) * 1 000 000 000. Unlike PPM, IPB replaces the number of defective parts with the number of complaints. From the calculation formula, this is relatively more fair and accurate, and can better reflect the actual quality performance of suppliers. Because if one supplier A complains only once, but the corresponding number of defective products is several hundred thousand, and another supplier B complains 10, then the number of defective products complained each time is only 1-2. With the same number of delivered parts, the PPM of supplier A is obviously higher than that of supplier B, but the quality of supplier B is actually worse.

3. ranking: ranking. This was introduced by Renault Group the year before last (20 16), and it was also used to replace PPM. Renault's ranking is for all suppliers' factories and is calculated as the sum of the accumulated scores for three months. Every complaint will be graded according to the influence of defects, the number of parts, whether it will be reissued and other factors. When the impact is large, numerous and repeated, the score may reach more than 100. This has a great impact on a factory with a goal of 7. But this calculation method is more reasonable than PPM and IPB.

4. The number of complaints is an index that must be evaluated. The more complaints, the more problems and the weaker quality management. This is also related to the number of parts delivered. If the total number of parts is large, the probability of complaints will be higher.

5. Stop queuing. The target is the 0 stop line. The shutdown of the vehicle factory is a very serious problem, and the shutdown claim is also very expensive, thousands per minute. This is a huge cost for both automobile manufacturers and suppliers, so it must be avoided. This is also the reason why many automobile manufacturers now have permanent suppliers. With the resident staff, many emergencies can be handled in time to avoid disconnection.

6. Market claim, aiming at market parts, such as guide rails and door hinges. This kind of relative influence is also great, which requires a lot of energy and money to deal with, and the most serious thing is recall. The target is also 0.
