What is the difference between layout inspection and product audit?
Product audits are performed on a regular basis in accordance with a predetermined plan to ensure that the product meets the intended requirements. Layout inspections involve the inspection of a finished product in which we check all dimensions and perform functional tests to ensure that the product meets the customer’s requirements.
1. Product audit is concerned with the past, while layout inspection is concerned with the present and what we want to accomplish in the future.
2. Product audit is concerned with validating the intended requirement, while layout inspection is concerned with whether the intended requirement is relevant and if the real need is met or not.
3. When we pick up a control plan for product audit, you will see that there are some product characteristics that are not only about measurements but also about the inspector, the inspector’s qualification, the sample frequency, and everything else about the product audit. Layout inspection, which is done at a specified frequency, which can be 6 months or 12 months depending on customer requirements, requires us to inspect all possible dimensions and functional tests, which may be the lifespan of the part, as well as all tests that are conducted as part of layout inspection.
4. Product audits are performed on a sample basis and at various phases of the manufacturing process, including labeling and packing. However, layout inspection is concerned with the final product and primarily determines whether or not it complies with the requirements.
5. Product audit is concerned with the efficacy of the quality management system in relation to the product, while layout inspection is concerned with the current situation at this moment.
6. The purpose of a product audit is to determine if the product has complied with the requirements since the previous audit and, if not, what needs to be done. Layout inspection will include a dimension inspection to ensure that all of the specifications mentioned in the design are satisfied, as well as a look back two or three years to determine where the trend is heading.
