7 Comprehensive Steps for Product Quality Inspection

Nowadays, savvy consumers always prioritize product/service quality. Therefore, effective product quality control helps businesses attract and retain customers. Ensuring quality will eliminate price as a significant barrier for your items. Let's explore the 7 most comprehensive steps for product quality inspection with KNA CERT.

Company Quality Management Process

Step 1: Apply Quality Standards

Currently, there are numerous quality standards for different products, including:

  • Food standards: HACCP, ISO 22000, FSSC 20000, BRC, IFS, ...
  • Quality management system standards: ISO 9001, ISO 17025, ISO 13485,...
  • Product standards: CE MARKING, UKCA MARKING, MS (Malaysia),...
  • Harmonized standards

In addition, businesses may adhere to certain quality standards set by external agencies and organizations: quality/safety inspections, industry associations, government regulatory bodies, etc.

Apply Standards to the Company's Quality Management

However, certain fields may lack specific quality standards. Therefore, businesses need to develop their own standards. Quality standards in each department within the business may differ, but they share a common requirement: they must be measured objectively.

Step 2: Determine Key Quality Criteria

While everyone aims to ensure quality in all aspects of product production, achieving this seamlessly from the outset is challenging. Therefore, businesses, when starting out, should focus on the most crucial criteria.

Key criteria refer to product/service characteristics directly impacting profitability and customer experience. Prioritizing these criteria enables businesses to save resources and still achieve desired results quickly.

Step 3: Build a Product Quality Management Process

Following the above steps, businesses need to establish a detailed and scientific plan to deploy the most effective quality control process. A well-designed quality management process results in high-quality products/services. Creating a consistent process enhances the quality of products/services.

To develop an appropriate quality management process, businesses must gather comprehensive information about the organizational context, customer requirements, and the needs of relevant parties. Additionally, adhering to key criteria helps design the most suitable process.

Step 4: Deploy the Company's Quality Management Process

Once the product quality inspection procedures have been agreed upon and approved, the next step is to put them into practice. In this stage, employee training assumes a pivotal role. Key personnel and employees directly involved in product/service-related tasks must comprehend their requirements and responsibilities to prevent errors during the work process, ensuring quality output.

Step 5: Evaluate Implementation Results

Businesses can assess the effectiveness of their processes based on:

  • Business software
  • Financial applications
  • Accounting reports
  • Customer management tools
  • ...

The information collected will help the business accurately assess its quality management. The company needs to compare the data collected with the initial plans and criteria to determine whether the desired results have been achieved. If not, the reasons why and the areas that need adjustment should be identified. It is advisable for the business to carry out this step multiple times to provide the most visual and accurate insights.

Step 6: Gather Feedback

After evaluating the implementation results, businesses need to conduct internal and external information surveys.

Internal information surveys involve gathering feedback from company employees, examining whether there were any difficulties in implementing the process, and soliciting suggestions for improvements to ensure effectiveness.
External information surveys involve collecting feedback from customers, assessing their satisfaction with products/services, understanding their preferences and dislikes, and determining if they have any suggestions for changes to products/services.

Step 7: Implement Quality Improvements

The final step in the product quality control process is to review, modify, and supplement the company's plan. Each customer stage will have different requirements, and market needs are constantly changing. Therefore, businesses need to continually improve to avoid stagnation.
