Click on the current stage of your sourcing or product development journey below to explore our related quality solutions.
The product development life cycle begins with idea generation, concept development, and market testing. For example, the E-Bike handlebar is designed with the form, fit, and function in mind that best serve the market/user’s requirements and the overall aesthetics of the final bike. Although Pro QC do not actively get involved in this stage, a postmortem investigation with many of our client often reveals the following challenges. Supplier Risks & Challenges: Misalignment between the buyer, supplier sales department, and factory production department on critical design requirements Advance product quality planning was not factored in early enough Difficulties in transitioning from a prototype supplier to a mass manufacturing supplier
In this stage, the engineers will refine the design and define the engineering specifications of the handle such as material properties, dimensions, weight, and other requirements while satisfying different product and safety compliances. This is also the stage where engineering prototypes (engineering build) are made to rigorously test the form, fit, and function of the product. Pro QC’s Quality Solutions: First Article Inspection (FAI) Supplier Development Services Resident Supplier Quality Resourcing Supplier Risks & Challenges: Poor communication of the technical details between buyer and factories Misalignment on the new product’s specifications Misalignment on design/engineering revisions
Once the component specifications are defined, the procurement department will begin to identify a list of suitable suppliers that can potentially meet their requirements in terms of capabilities, cost, capacity, and quality. Pro QC’s Quality Solutions: Onsite Supplier Verification Financial Credit Check Supplier Risks & Challenges: Lack of experience and due diligence in new supplier region Communication challenges Concern about supplier scams Low confidence supplier’s trustworthiness Concerns over supplier’s financial viability
Once a list of trustworthy suppliers has been identified, an evaluation of supplier reliability is recommended to ensure they can produce at a consistent level of quality. A world-class organization usually has a comprehensive supplier qualification program to identify and mitigate the risks associated with quality, safety, on-time delivery, cost, and compliance. Pro QC’s Quality Solutions: Global Supplier Audit Programs Supplier Quality Audit for Potential Suppliers Quality Management System Audit Social & Ethical Audits Supply Chain Security Audit Environmental Audit Supplier Risks & Challenges: Suppliers are not as capable as they initially claimed Supplier lacks effective and systematic quality assurance practice Supplier is ISO 9001 certified, but the underlying principles are not implemented in practice Mass production quality does not match prototype quality Buyers want to sell to big retailers, but their suppliers do not yet comply with the retailer’s supplier code of conduct Supplier violation on labor law, ethical and environmental compliances Goods held in customs due to supply chain security malpractice
Before commencing volume production, it is crucial to validate the factory’s equipment, staffing, production methods, capacity, and quality control plan for each product line. This is an important stage to prevent critical failures, costly mistakes, and loss of time due to changes and rework. Pro QC’s Quality Solutions: Engineering Build (EB) and Quality Build (QB) Audit First Article Inspection (FAI) APQP/PPAP Audit Manufacturing Process Audit or VDA 6.3 Process Audit Supplier Risks & Challenges: Factory not ready for mass production Shipment delays due to critical failure, poor quality, and resource constraints An exponential increase in defective products Product recall High Cost of Poor Quality An exponential increase in the cost of change after mass production commences
Production planning is an administrative process that involves ensuring that sufficient raw materials, components, staff, and other outsourced processes such as secondary processing are procured to create finished products according to the specified schedule. Pro QC’s Quality Solutions: Order Expediting Supplier Risks & Challenges: Production delay due to poor material procurement planning Production delay due to inadequate production staffing Poor sub-supplier management
Incoming quality control is required when all the procured material and components arrive at the factory. This is the first step in controlling the production process and resulting product quality. Understanding how a factory manages its incoming material and its supply chain is a very good indication of its commitment to quality. (The saying goes: Garbage in, garbage out.) Pro QC’s Quality Solutions: Incoming Inspection In-Process Inspection Manufacturing Process Audit or VDA 6.3 Process Audit Supplier Risks & Challenges: The factory does not manage the quality of its supply chain or is poor at supplier management Suppliers turn a blind eye to defective components during incoming and still use them for production and assembly Using sub-standard material or components (e.g., lower-quality fabric than required) Substituting lower-cost alternatives for product components (e.g., cheaper electronic components in a mobile phone) “Quality fade” where suppliers make small, gradual substitutions in materials and components over time Bulk material ordered by the supplier degrades over time due to poor storage conditions
Upon approval for volume production, raw materials and components are processed, extruded, forged, cast, injected, machined, and assembled. It is important to note that a factory may not have all the production capabilities and may outsource certain processes to other suppliers. Pro QC’s Quality Solutions: First Article Inspection (FAI) In-Process Inspection Manufacturing Process Improvement Quality/Root Cause Investigation (8D) CAPA Verification Order Expediting & Production Monitoring End-Of-Line Testing & inspection Supplier Risks & Challenges: Operators are not producing according to the production control plan Supplier is under pressure to ship goods, turning a blind eye to defective components Lack of quality staff to enforce quality control Poor control of re-worked material/product Mistakes made by temporary, untrained staff/operators Communication breakdown when the supplier is under pressure
Packaging and labeling of the goods are the last steps before shipping. The smallest aesthetic defect on the packaging or missing components often leads to customer returns, and a misplaced label often leads to compliance issues. Pro QC’s Quality Solutions: Manufacturing Process Audit Poka-Yoke Implementation Pre-Shipment Inspection End-Of-Line Testing & inspection Supplier Risks & Challenges: Products are poorly packaged Human mistakes and missing components lead to customer returns Wrong labeling leads to compliance issues and significant re-work
Packaged products are being loaded by suppliers at the factory or warehouse into containers and shipped to their final destination. Pro QC’s Quality Solutions: Container Loading Supervision C-TPAT Audit Supplier Risks & Challenges: Rough handling of goods during container loading by the factory or outsourced warehouse, leading to damaged product Poor container loading leads to product damage during transit
