Manage quality and control quality

◈ Manage quality transform the quality management plan into executable quality activities , The main purpose is to ensure that the project process is observed and met , And implement product design and process improvement .

◈ Quality control is to evaluate performance , Ensure project output is complete 、 Correct and meet customer expectations , The process of supervising and recording the implementation results of quality management activities . Its function is to verify whether the quality requirements are met , For final acceptance .

◈ Both quality management and quality control are carried out according to the quality management plan , All for quality improvement , The former focuses on the process , The latter focuses on results .

◈ The verified deliverables are the outputs of the quality control process , It is also the input of the range confirmation process . This means that before the customer accepts the deliverables , Quality control activities shall be carried out within the team , Confirm that the deliverables meet the customer's needs .

◈QP（ Quality Planning ）、QA（ Implement quality assurance ）、QC（ Implement quality control ）.

◈ Attribute sampling ： The result is “ Yes or no ”、“ Yes or no ” etc. ;

◈ Variable sampling ： Quantitative scale measurement , The ability to determine the process .

◈ Independent events ： The occurrence probability does not affect each other , Their probability of occurrence is equal to the product of their own probability of occurrence ;

◈ Exclusion events ： Events that cannot occur at the same time , The sum of the probabilities is equal to 1.

◈ Control chart ： The seven point rule ; Is it out of control ; The upper and lower control limits are generally ±3∑ The location of ; Used to detect any type of result variable , Through sampling inspection of products , Help determine whether the results meet the requirements 、 Whether the deviation is acceptable 、 Whether a process is stable , And whether there are predictable performance results ;

◈ Benchmarking ： Learn from the good practices of other projects of the company or foreign companies , Learn from others' strong points and close the gap , Ways to generate improvements , Or provide a set of standards to measure performance .

◈ Experimental design （DOE）： A statistical method for determining which factors will affect a product or process ; All important factors can be systematically changed at the same time , And show the impact on the results .

◈ Statistical sampling ： Replace all inspection with sampling inspection .

◈ Cause and effect diagram （ Ishikawa 、 fishbone diagram ）： Show how different causes lead to potential problems or results ; Emphasize the results 、 The root cause ; Histogram ： A histogram showing the release of various variables affecting quality , The basis of Pareto technology ;

◈ Pareto Diagram ： Histogram drawn from large to small according to the frequency of the problem ; The specific application of the 28 principle ; Emphasize that most problems are caused by a few reasons ; What are they? , Who is the biggest ;

◈ Trend chart ： Reflect the trend of a process from the past to the present , Good or bad , Do trend analysis , Forecast the future ;

◈ Scatter plot ： Determine whether there is a possible connection between the two variables , Characteristic is 2 All variables are known , See if it is relevant . The quality that customers are satisfied with is ： Meet the demand 、 Suitable for use .

◈ Deming's theory ： The goal remains the same 、 Continuous improvement and knowledge accumulation ; Dai Ming ring -PDCA loop ; Keep a strict check on 、 Prevention is better than inspection ;

◈ Juran theory ： Applicability ; It defines the difference and relation between quality and grade 、 Quality ternary theory ;

◈ Krusby's theory ： Four basic principles ： The definition meets the requirements 、 Quality comes from prevention 、 Perform zero defect 、 Inconsistent cost measurement ;

◈ Taguchi's theory ： Apply statistical techniques to quality management , Through the loss function, we can judge the cost of not meeting the target product . As long as the process is under control , Do not adjust .

◈ Specific results test has been completed , The customer does not believe the test , It indicates that the definition of quality plan is not sufficient .

◈ Total quality management puts forward that quality is everyone's responsibility .

◈ The quality work is led by the upper management .

◈ Implementing quality control is a verification process 、 Build confidence .

◈ At quality control meetings , The approved change request shall be reviewed for confirmation of implementation , Review the project gains and losses and lessons learned .
