Zhu Lan put forward the viewpoint of "quality ternary theory", which divided the management process into three steps: planning, control and improvement. This is the famous "Zhu Lan Trilogy". The setting of each link in Zhu Lan Trilogy has its own specific reasons. Steps:

The first step: quality planning is necessary, and it is essential to establish a working procedure that can meet the quality standardization.

1, identify the customer. 2, clear customer requirements. 3. Develop products that meet customer needs. 4. Establish product goals

5. The development process conforms to the product objectives. 6. Demonstrate process capability

Step 2: Quality control.

Quality control can provide reference and basis for mastering when to take necessary measures to correct quality problems, and it is an important link in the trilogy.

1, select the control point. 2. Select the unit of measurement. 3. Set the measured value. 4. Establish performance standards. 5. Measure actual performance. 6. Analyze the difference between standard performance and actual performance. 7. Take corrective measures

The third step: quality improvement.

1, more reasonable and effective management methods are often excavated in quality improvement. 2. Determine the improvement project. 3. Organize the project team. 4. Find the reason. 5. find a way to solve it. 6. Prove the effectiveness of the measures. 7. Dealing with cultural conflicts. 8. Take control procedures for the results.

The three steps in Zhu Lan Trilogy have their own goals and are interrelated. As a successful ladder to achieve quality management objectives, it needs some other conditions to be effectively implemented, such as positive leadership and environment and strong support for quality.

Without a perfect quality culture as the foundation, even if the "Zhu Lan Trilogy" has great "magic power", it can't fully play its role, because in complex enterprise management, a small factor may have an impact on people at all levels of the company, not to mention "leadership" and "environment" are not small factors that can be ignored at will!

Extended data:

The expansion of the scope of quality management activities is mainly based on the viewpoint of "triple roles". Under the guidance of this view, the executors or departments of any work all work around the three roles of customers, processors and suppliers.

1, as a good customer.

Suppliers should understand and agree with their own views and document them; Return defective supplies to suppliers quickly and skillfully; Feedback supply quality data to suppliers.

2. As a good manager.

Quality and technical data should be studied and used; Continuously improve the process and reduce defects; Demonstrate process, defect level and continuous improvement project documents.

3. As a good supplier.

Understand customer needs, identify and record delivery capabilities; Reduce output defects and fluctuations; Measure the quality of output from the customer's point of view.
