2. Contact with related department to make the emergency measures
If we can handle with these problems then our QC will finish it but if we can`t then we may ask other department to solve it.
As to the same problem,there are so many reasons,sometimes we can know it easily with rich experience,but sometimes we need to find the reasons by some steps as follows,
Step 1: Again to see the problems
Try to observe the problems from every aspect,try to record the data.
Step 2: Find out the reason
(1) Simulation method. Use the same combination of factors of production, confirm whether can lead to the same bad phenomenon.
(2) Matching method. Will factors of production are combined according to certain conditions, to confirm what kind of combination will lead to the same problem.
(3) Exclusions method. Replace the factors one by one, when the bad disappear, chances are the factors of production caused by issue.
(4) Correlation method.Compare the good with the bad product to find out the difference, these differences are likely to be the cause of the problem.
The above methods only can find out the factors and laid the foundation for countermeasures, but it is not enough, also need to give disproof, especially in the theoretical calculation, attention following items:
(1) Using high-precision test equipment acquisition data as far as possible.
(2) Plan approval, impartial while reading data,do not artificially changed data.
When find out the reasons,we must carry on the countermeasure, bad countermeasures is not simply a processing, underground, repair instructions, but to make the overall saving method, the agenda, the undertaker.
(1) Countermeasures to the clues, material
A. How to deal with item materials?
B. How to deal with semi-finished products?
C. How to deal with finished products?
D. How to deal with products have been sale to the market?
The above project, how many pieces?What time do you start to deal with?Who's responsible for bear?Where is the processing?
(2) Countermeasures in time for clues.
A. When will take into the new rules 4M（Manpower，Machine，Material，Method）?
B. When will finish the bad quality?
C. When the bad quality can be sale again?
The above project, how many pieces?What time do you start to deal with?Who's responsible for bear?Where is the processing?
(3) Countermeasures to the clues and operation method
A. Any new process for the production?
B. Any new method for QC inspection?
C. Any change for the rules by QC?
The above project, how many pieces?What time do you start to deal with?Who's responsible for bear?Where is the processing?
When a lot of bad product happen, or even want to consider to stop production, priority nonconforming.If the cost of the treatment of the poor is more than make new products, it might consider non-conforming waste processing.
