When exactly should usability testing for a product be conducted?
Is it before or after production has begun? The answer is not as simple as you think. Come with us we explore a few critical points.
Typically, an importer will test two different kinds of samples against using AQL sampling in two different stages of the production process:
1) First, the pre-production samples that the supplier provides before the start of mass production are tested for quality standards.
2) Secondly, product testing is also done for final product units once their mass production has been completed.
Testing before Production
Just like it happens in the case of inspection, product testing that’s conducted earlier in the production process — or even prior to the beginning of production — can help you avoid later issues that could negatively impact a majority of your order. It’s at this stage that importers try to minimize the risk of product defects through the establishment of a Golden Sample.
Any time you’re working with a new supplier or making a new product from scratch, it’s always advisable to ask the manufacturer to provide you with a product sample before the mass production of your goods kicks off. That’s regardless of if you have plans of testing the finished products in a lab or not.
By getting this product sample early and looking at it, you’ll be in a position to make sure that the person who’s making them fully understands what you want. Besides, you’ll be able to check if they’re meeting your design requirements and quality standards so that if there’s any corrections or modifications to be made you can give those instructions before it’s too late.
Still, some importers will go one step further and request a product sample even at the earliest stages of negotiations with potential suppliers to assess whether that particular supplier is capable of meeting the level of production capabilities that the importer is seeking.
Testing after Production
If you plan to introduce testing services for product units from mass production, then you can ask your quality control inspector to pull a few samples of production units during the inspection stage and then either:
• Conduct some elementary on-site testing at the concerned factory; OR
• Seal and send the product samples to a testing services lab for testing there.
By having your quality control inspector pull samples right at the factory level, you’ll be making sure that they’re genuinely random samples that are representative of the whole order. If you depend on factory workers to pull for you samples of the product, you risk having them “cherry-pick” for you the best samples or those that are regulation-compliant and in the best condition. You can’t rely on factory staff to get for your product samples that are representative of the entire order. Not at all!
Testing in Accreditation Lab
By sending product samples to an accreditation lab for quality testing, you’re able to verify both the safety and the performance of the materials and the components used. Further, you may have to conduct independent testing for each stock keeping unit (SKU), more so if the products are made using different materials.
However, AQL sampling tests only a number of the units for each SKU is normally sufficient since materials used and manufacturing processes applied are often consistent across an entire unit order.
