If quality control is important to you, you may want to learn a little about pre-production inspection (PPI) PPI is a type of quality inspection. Many companies rely on them when they start working with a new supplier or when they sign a very large contract. Pre-production inspections make it easy to see if your supplier is cutting costs and delivering the product you want.
What is a pre-production inspection?
A pre-production inspection takes place after a supplier or factory has been identified and evaluated. Its main purpose is to identify quality risks before production begins. Pre-production inspection can be carried out before the start of production or before the start of the final assembly.
- Clear understanding of the production plan
- Ability to anticipate potential problems that may affect project schedules and product quality
- Ensuring that customer requirements are met
- Ensuring the quality of raw materials and product composition
Why is testing before production so important?
Pre-production testing is one of the cornerstones of risk assessment and quality assurance management. Without pre-production inspections, you have no systematic way to ensure that your suppliers are ready to start production, that they meet specifications and that they comply with quality requirements.
These inspections can bring many benefits to your business. If you select to hire any person or organization to perform pre-shipment inspections, you can
- Reduce the risk of supply chain disruptions
- Have the opportunity to check the production readiness of your suppliers.
- Assess the manufacturer’s ability to meet customer needs and quality objectives.
When should my company consider a checklist before production?
Pre-production inspections offer many benefits to companies. While it doesn’t solve all quality control problems, it can help you start production on time.
A pre-production inspection also gives you an overview of the most important elements of your production process. If you want to learn more about a project’s materials, potential prototypes, and/or mass-produced products, your company should consider pre-production inspection.
For projects that involve a lot of manual labor, an in-production inspection may be more useful than a pre-production inspection.
