What are the different types of quality control? How can quality be audited internally using the FMEA method?

THE DIFFERENT TYPES OF QUALITY CONTROL

INTERNAL QUALITY CONTROL

Internal quality control is the first line of defense in the manufacturing process. It involves the monitoring and evaluation of production processes by an in-house team, with particular emphasis on compliance with internal standards and regulations. This enables anomalies and defects to be identified quickly, guaranteeing consistent product quality. For example, in the automotive industry, rigorous internal control is carried out at every stage of assembly to ensure safety and performance.

EXTERNAL QUALITY CONTROL

In contrast to internal quality control, external quality control involves assessment by an independent external entity. This may include audits by regulatory bodies or inspections by customers. This approach offers an objective, unbiased perspective, increasing credibility and confidence in the product.

A study published by the International Organization for Standardization (ISO) has shown that the adoption of external quality control can significantly enhance a company's reputation in the global marketplace.

STATISTICAL QUALITY CONTROL

Statistical quality control uses mathematical and statistical techniques to assess and maintain quality. By analyzing data collected from various production samples, this method provides a deeper understanding of quality variations and can predict potential defects.
In the pharmaceutical sector, for example, statistical quality control is used to monitor the concentration of active ingredients, ensuring drug efficacy and safety.

ADVANTAGES AND DISADVANTAGES OF EACH TYPE

1) Internal quality control :

Advantages: Direct control, rapid identification of problems, generally lower costs.
Disadvantages: Potential for bias, less external credibility.

2) External quality control :

Advantages: Impartiality, enhanced reputation, compliance with international regulations.
Disadvantages: Higher costs, less control over process.

3) Statistical quality control :

Advantages: Accurate analysis, early detection of variations, applicability to various sectors.
Disadvantages: Requires specific skills, can be costly in terms of time and resources.

Each type of quality control offers unique advantages and presents specific challenges. The choice between these methods depends on the needs, resources and objectives of each organization. Combining these approaches can often lead to a more robust and effective quality control strategy.

INTERNAL QUALITY AUDIT METHODS

INTRODUCTION TO QUALITY AUDITING

Internal quality auditing is a systematic, independent procedure for assessing the conformity and effectiveness of an organization's processes and systems. It is an essential tool for ensuring operational excellence and customer satisfaction.
ISO 9001, the international standard for quality management, emphasizes the importance of internal audits in maintaining and improving performance.

AUDIT PREPARATION

Preparing for the audit is a crucial step. Here are the main points to consider

- Definition of objectives: Clarify the purpose of the audit, whether compliance, performance or other.
- Selecting the auditor: Choose a qualified and impartial auditor to ensure the integrity of the audit.
- Detailed planning: Establish a timetable, define the scope of the audit and prepare the necessary documents.

CARRYING OUT THE AUDIT

Performing the audit requires methodical execution and attention to detail. Steps include :

- Document review : Study of existing processes and systems.
- On-site observation: Inspection of operations and procedures in action.
- Staff interviews: Communication with stakeholders to understand actual practices.

AUDIT EVALUATION

The evaluation of the audit lies in the analysis of the results and the formulation of recommendations. This involves :

- Analyzing the data collected: comparing results with standards and objectives.
- Identify discrepancies: Identify non-conformities or opportunities for improvement.
- Writing the audit report: Compiling results, observations and recommendations in a clear and concise manner.

The emphasis is on providing accurate and relevant information that can guide the organization towards continuous improvement.
