Characteristic factors include analysis chart, Plato, look-up table, hierarchical method, scatter chart, histogram and control chart.

Seven new technologies of quality control;

Relationship diagram, system diagram method, KJ method, arrow diagram method, matrix diagram method, PDPC method, matrix data analysis method.

Five principles:

People, machines, materials, law and environment

Human-human resources: human ability, consciousness and operation. Can be improved through training.

Machinery-equivalent to the infrastructure mentioned in ISO9000. For mechanical equipment, production capacity, equipment maintenance and timely maintenance should be considered.

Materials-The materials used to produce raw materials and form products should be qualified or processed to meet product requirements, so as to avoid unqualified products due to raw material problems.

Method-process method constitutes the technical component of the product. Reasonable technology will reduce the product cost and improve the qualified rate. It can be said that reasonable technology and correct production operation flow constitute qualified products.

Environment-production environment, pollution can be avoided by monitoring the production environment (which is very important for food production). For site management, standardized production site represents safe production and orderly production.

Extended data

QC is the abbreviation of English quality control, and Chinese is "quality control". In ISO 9000: 20 15, quality management is defined as "guiding and controlling the quality coordination activities of the organization". Quality control is defined as "a part of quality management, committed to meeting quality requirements". According to the control characteristics and sequence of products in the process, product quality control can be divided into four stages: incoming quality control (IQC), process quality control (IPQC), final inspection and verification (FQC) and ex-factory quality control (OQC). In order to meet the quality requirements, the organization will set up quality management and quality control departments, and arrange quality control personnel engaged in quality control functions. Generally, quality control functions are shared by quality inspectors (QC) and quality engineers (QE).
