Huawei R & D reading-26 (pilot project, Quality Assurance)

Pilot Project: The Cradle of mature products

Before the establishment of the Pilot Project Department of Huawei, after the R & D personnel developed the product, they tried it and thought it was okay,
In a hurry, I handed it over to the production department. I thought it was all done, and then I went to develop new products myself. The result is batch production.
Various problems have emerged: low pass-through rate in the production process, high waste rate, and small
Batch accidents: many quality problems occur during batch production. unknown reasons: the shipment list is incomplete, which is not delivered before shipment.
If this is missing, the entire system cannot be formed: Problems with product installation are found before shipment ...... Shipped in the market
Under pressure, R & D personnel urgently solve the problem on the production line, and regard the production line before shipment as a laboratory for solving the problem:
The company even found a missing line before delivery of urgent procurement at several times the high price.
In July 1995, Huawei's pilot department was established together with the Central Research Department. The pilot Department became an important part of Huawei's R & D system.
The mission is to accelerate the maturity of product R & D achievements. At the beginning of the pilot project, there were about 30 persons, and there were trial departments and tests in progress.
Heart. The trial production department is responsible for product trial, training personnel, solving the most urgent product quality problems, and deepening the pilot test
Work awareness. The test center includes the hardware testing department, software testing department, and testing lab.
Huawei, which has always put product quality first, adopts the reverse thinking in terms of the ratio of personnel in the pilot test department to the Central Research Department.
Path. The R & D department is known as a R & D factory, with a large number of undergraduates doing research and development. The pilot project is a dam of product quality and is widely used.
Doctoral students should be the department with the largest number of doctoral students in Huawei's R & D system. Zheng Shusheng, executive vice president of Huawei, And Hong tianfeng
I have worked as the head of the Pilot Project Department.
After the establishment of the pilot department, the product quality of Huawei was significantly improved. By 1996, the staff of the Huawei pilot Department expanded to approximately 300.
The ratio of people to R & D personnel is roughly, that is, every two R & D personnel has a pilot engineer. After December 1996,
Huawei's pilot testing department has also added: Technology Experiment Center, Equipment R & D center, Material Quality Test Center, BOM center and Technology
File center.
The Process Test Center is mainly responsible for the process design of new products, improving the production efficiency during batch production, and reducing
Cost. The Equipment R & D center is mainly responsible for testing equipment and jigs required during the production process, as well as the development and,
Import and integration.
The material quality test center provides technical support for mass production of materials. In the past, R & D personnel of the R & D department were
When materials are used, they are always under consideration. No matter what materials are captured, they will be used. After the materials are used, it will be discovered that it is difficult to purchase or
Batch testing is not enough, and long-time use of anti-aging performance indicators does not work, and so on. At this time, it is necessary to replace materials, which means that
All procurement is decommissioned, and the delivery time of the product is infinitely prolonged; some materials cannot be changed at the moment, and the design needs to be changed for replacement,
Then we need to re-launch all the products. Even some products are forced to mount a resistor or capacitor during delivery for emergency response.
The establishment of the Material Quality Center has changed the randomness of R & D materials. materials that have not been tested by the material quality testing center,
It cannot be selected in the design, which greatly improves the maturity of R & D design.
Bom center and technical document center. Bom is the materials list purchased by the company,
Specifications, quantities, manufacturers, and other information are the basis for procurement and production, and the basis for sales quotation. If Bom is not set, it is purchased
The cost cannot be accurately calculated, so the quotation made to the customer cannot be accurate. Technologies including BOM files
Technical documents are used to guide production line workers and engineers in bulk production. In the past, the R & D department was responsible for these important materials,
The result is that one version is followed by one version. Today, the Sourcing Department has not purchased materials based on the BOM, and immediately receives a notification from the R & D department.
The BOM needs to be modified because a component is added or changed, resulting in the entire company's Purchase Department,
The pricing center and Production Department are all busy. Later, the pilot Department established the BOM center and the technical documentation center
The Department and personnel of the Department conduct the pre-release review to reduce the possibility of errors.
Repeated questioning found many potential problems. In addition, the BOM center has developed a mechanism for R & D personnel to change the BOM and treat the BOM at will.
The rewards and punishments system for behaviors such as not being serious improves the management level of BOM and technical documents.
At the beginning, the R & D personnel had a conflict with the pilot project department and felt that they had put a shackle on their R & D work, which affected the work.
Efficiency. However, after the operation of the pilot department, Ren zhengfei confirmed the work of the pilot Department several times within the company, and R & D personnel also
It was found that the overall product R & D efficiency was improved, and the pilot Department quickly integrated Huawei R & D work and processes, making it indispensable.
Important links.
Unlike the R & D department, the pilot department is on the R & D stage and can announce that "we have made a new product" is so excited.
The task is to optimize and stabilize new products. It is to repeat the tests and optimization work to build a product for new products.
Quality Seal, "This product can be produced": it cannot be vigorous, but it can only be unknown. Pilot engineers
Each power cord, each ground wire, and each signal line are not properly connected, and the Board is in different environments.
Whether the stability is reduced or not. After the pilot test, mass production is required and then delivered to users,
As a result, engineers in the pilot project team are under pressure every moment and need to maintain a high degree of responsibility. Engineers from Huawei qilang
The slogan "taking the bench for ten years" is put forward. They are the "Dam" of Huawei's product quality ".
