Above all what is we will understand 5M1E?
A) person (Man) : The handlers understanding to quality, skilled state of degree, body;
B) machine (Machine) : The machine equipment, precision that measures an instrument and state of care and maintenance;
C) material (Material) : Function of the composition of material, physics and chemical function;
D) method (Method) : Here includes to produce alternative of craft, facilities, operating rules to wait;
E) measures (Measurement) : The method that basically points to when to measuring, be adopted whether standard, correct;
F) environment (Environment) : The temperature of working ground, humidity, illume and clean condition;
Because the first letter of the English name of these 5 elements is M and E, so Chang Jian calls 5M1E.
We know working procedure is the basic link that the product forms, working procedure quality is the foundation that ensures product quality, working procedure quality pledges to the product efficiency of cost of quantity, production, production is having main effect.
Working procedure standardizes exercise to having crucial effect to the assurance of working procedure quality, working procedure standardization has prominent place in working procedure improvement in quality.
Working procedure quality suffers 5M1E namely the person, machine, makings, law, annulus, effect that measures 6 respects factor, working procedure is standardized even if want to seek the standardization of 5M1E.
So how do we control these 6 elements to form standardization to stabilize the purpose of product quality in order to achieve?
1, operation personnel element (person)
The person’s analysis:
1) skill problem?

Working procedure standardization put forward to make clear a requirement to 5M1E, in the integral plan that we answer to standardize working procedure the job to bring into working procedure improvement in quality. Making relative standard change requirement foundation to go up, pass the investigation of working procedure quality and analysis, discover working procedure standardizes each executive deviation of specific requirement, adopt then improve measure. The abidance that passes working procedure improvement in quality circulates, come true truly and improve what stimulative working procedure standardizes continuously, the abidance that realizes working procedure quality thereby is improved.
Add: The application of 5M1E
Working procedure standardization: Exercise of working procedure standardization is right the key of working procedure quality, working procedure standardization has prominent place in working procedure improvement in quality, working procedure quality suffers 5M1E namely the person, machine, makings, law, annulus, effect that measures 6 respects factor, so duty standard is changed even if want to seek the standardization of 5M1E;
Improvement in quality: 5M1E is 6 main factors that affect product quality, it is the main way that analyses quality problem generation;
Management improves: 5M1E is spot management is essential, it is the main orientation that promotes level of management;
Design plan test and verify: 5M1E analysis and test and verify undertake adequately in design phase, can make devise plan more accord with working work requirement.
Solve a problem:
5M1E is the direction that we are analysed and ponders over a problem, should solve spot problem to be united in wedlock with photograph of other government tool even use, improve measure accordingly in order to discover the prime cause that the problem arises is made. Common tool has the following kinds:
1, fishbone pursues / fish bone pursues / Ishikawa graph analyses a way
2, fault tree analyses a way
3, brains storm law
