What are the 7 basic principles of Quality?

This is a set of tools whose use helps ensure quality compliance within organizations and should be disseminated to the whole of workers to be applied correctly.


The seven basic principles of quality are:

1) Final Inspection

It should be performed every time we implemented a new process, we launched a new product or have had a quality problem with a customer and we want to test the effectiveness of the solutions adopted.

The basics of final inspection:

It is general check of the product or service in terms of functionality and quality.
The person in charge to realize it must have very good knowledge of what will inspect (service or product).
Inspection specifications must be checked by the quality manager. Thus the inspection must be clearly defined and standardized. There are visual aids for conducting the inspection (as the panoply of defects) and checks are updated according to customer requirements, with clear instructions on the frequency thereof and judgments about product OK.
2) Auto-Control

It is control the quality of output resulting from a process by the person who just what to do.

The basics of self-control:

The operator controls the quality of output that just made following the control points marked by an instruction of self-control.
The operator decides whether the output is compliant or not by comparing a sample template. Panoplies are common defects.
If the output is not correct, it departs (store in red containers). If as it is transferred to the next station.
The operator must be informed immediately if you make a mistake and transmits an output nonconforming to the next station.

The methodology of red containers is based on the principle of immediately separate the nonconforming from the rest indicating the reason for rejection.

The fundamentals of the red containers are:

Red containers are visible and are located near the operator.
As it has identified and marked the defect.
Both what is to repair what it is to eliminate must be clearly separated, a container for each type.
Red containers should be analyzed and emptied daily.
4) Rework under control

Rework is a non-systematic value-added operation without conducted in a product. Rework is a waste and should therefore be eliminated by addressing its root causes.

Rework fundamentals:

Each recovery is specific to a defect and its realization must be standardized.
Recoveries are made outside the main process when you have long or when it is technically impossible to do about it. It should be done in a specific job for it.
The recoveries of the process are carried out by the operator to detect the defect or by the responsible section.
Recoveries both outside and on process should be recorded by separate indicators.
5) Poka Yoke

Poka Yoke is a simple and reliable device which prevents:

The error caused by the defect is given.
The transmission of a defect on the next station that has occurred.
The foundation of Poka Yoke is to encourage the production of defects not being detected a posteriori. As always more expensive and traumatic.

The Poka Yoke need a validation system and frequent monitoring.

6) Ok the first piece

Changes or production stoppages are potential risk situations in the quality of products and processes. Therefore, the check on the quality requirements of the first piece produced is key to detecting these risks.

Detecting a defect in the first part requires:

Immediately stop production.
Analysis and solution of the defect.
Nonconformity report the defect.
7) QRQC (Quick Response Quality Control)

It is a methodology for rapid response to quality problems No answer, solve any kind of problem and learn lessons for the future.

6 QRQC key points are:

REAL PLACE: Go to where the problem occurs and when it occurs.
LIVE PARTS: See the actual pieces and compare the bad with the good.
LIVE DATA: Observing reality with our own eyes and not content with what we have.
QUICK RESPONSE: immediately reply to default and protect the client.
LOGICAL THINKING: At the end of the explanation of what is happening should be simple.
COACHING AT WORK: Monitoring, training, support, recognize.
