Quality Valve Status Description
As a control method of project management, the quality valve can be divided into three colors to indicate the elements and valve status; Customized high quality aluminum knobs
Description of element status:
Green indicates that the mission phase objectives have been reached or fully completed with no or very low risk;
Yellow indicates that the task has not been completed, or the time is delayed or there is a certain risk, and the action plan must be staged;
Red indicates that the task is not completed, or the time delay or high risk, there is no staged action plan or there is but not approved by the relevant team.
The status of the valve depends on the status of the retrospective elements, which can be divided into three identification descriptions:
Green: The quality valve is fully open, all elements are green (no red and yellow items), and the project quality goals are assured;
Yellow: The quality valve has a risk of opening, and the review elements have yellow elements, but no red elements, which means that the valve opening is risky, but there are corresponding measures to ensure that the goal can be achieved; Customized high quality aluminum knobs
Red: The quality valve does not open, the project has high risks, and there are currently no measures to ensure that the goal can be achieved. The project team should focus on solving high-risk problems. After the problem is solved, re-evaluate the red items until the valve is successfully opened.
Organization and management of quality valve:
The premise of the use of quality valves in engine projects is that all project team members participate in quality activities, and the responsibilities and rights of each department should be clarified; the following requirements should be paid attention to;
1 Organizational establishment of project quality valve
The quality valve review of each project should have a valve decision maker; the quality valve is divided into department-level, project-level, and company-level review according to the project level, and different levels of quality valve review correspond to different decision makers; a clear organizational structure can make the project The coordination, reporting and risk warning of product quality and improvement work during operation were carried out smoothly.

2 Clarify the monitoring function of “quality valve”
The department performing the quality control function must be authorized by the senior management and can have veto power over the approval status of each stage of the project. It mainly summarizes, coordinates and evaluates project progress, project operation status, product quality and improvement work in a timely manner. When necessary, the senior management shall be warned of risks in a timely manner. The quality control function personnel must have a strong sense of responsibility, comprehensive judgment and coordination ability, and have professional knowledge or experience in all lines of the company’s project management.
two cases
The following describes two examples that occurred during the development of new engine products to illustrate the importance of quality valves in product development;
1 The use of “quality valve” can effectively ensure the development of new parts in new products
The engine water outlet pipe assembly was found to be out of tolerance when the supplier’s sample size was 100% tested at the official tooling and sample delivery node of the product. After repeated debugging by the supplier, the maximum deviation was 0.25mm after spot welding. Risk assessment: enter the furnace after spot welding. Welds may be slightly deformed, which can lead to a leak failure mode during the hot test of the prototype assembly. Customized high quality aluminum knobs
The quality valve of the product project was closed during the Pre-QV review of the Gamma stage because of the risk of this problem. The project team organized engineering engineers, supplier parts quality control engineers, and quality engineers to spot welders of suppliers for the key points affecting the opening of the quality valve of the project. Check whether the assembly is qualified and whether the parts are qualified after spot welding; at the same time, re-measure the parts after brazing in the furnace to confirm whether the brazing will affect the size. If it does, the supplier is required to compensate for the spot welding in the previous process. Through the efforts of the team, before the official review time node of the project quality valve, the problem of the sample size of the water outlet pipe assembly parts being out of tolerance was solved.

Through this example, we can see that in the development of the project, a “quality valve” is set at a certain node to review and confirm the quality status of the project node, ensuring that the quality work of the project in each stage and each region meets the requirements, so as to ensure new When the product project is put into mass production, the quality status of the parts meets the requirements of the design drawings and customers.
2 The use of “quality valve” can effectively improve the qualified rate of product quality
Using the “Quality Valve” tool, through the statistics of the qualified rate of products at each stage, it can be seen that: under the control of the quality valve at each stage, the qualified rate of the workshop for one inspection is gradually improved, and the probability of producing unqualified products is gradually reduced. Soft landing for official mass production. Customized high quality aluminum knobs
Taking a LAQ model project as an example, the product qualification rate has gradually increased from 55.5% in the Gmma stage to 96.8% in the SOP, and the product qualification rate in the Gamma stage is 50.5% (the target is 95%). It can be seen from the construction problem that it affects the workshop products. The main problem of the pass rate is the instability of equipment and tooling. After improvement, the pass rate increased to 80% in the PPV stage. After the PPV stage, after adjusting the product process, the product pass rate in the Pilot stage increased to 93.2%. The reason for meeting the standard was found to be mainly due to the problem of quality control of parts after the supplier’s production capacity was improved, which revealed that the supplier’s personnel were proficient in the operation of new products and the equipment was stable. Project SOP node verification, the product qualification rate is 96.8%. achieve the goals set by the project.
To sum up, as an effective means of quality control in project management, “quality valve” can intuitively and timely reflect the crux of the problem through statistics and induction, which is conducive to the project to quickly concentrate resources to solve problems and ensure the project went well. Its application can be applied to quality control in the development process of other products, and can be used by other manufacturing systems not limited to GM systems.
