1. New Product Development

New product development lays the foundation for strategic sourcing. Prototyping is crucial to validate that the supplier understands the client’s requirements.

Pro QC inspections validate the new parts while our supplier development services align quality expectations with suppliers and strengthen their ability to meet quality requirements and reduce time to market.

Poor communication of technical details between buyers and factories
Misalignment of product specifications and critical design requirements among buyers, suppliers, and factory production teams
Inadequate consideration of advanced product quality planning
Challenges when transitioning from prototype suppliers to mass-manufacturing suppliers
Misalignment on design and engineering revisions

2. Supplier Selection

Once the component specifications are defined, the procurement department identifies a list of suitable suppliers that can potentially meet their capability, cost, capacity, and quality requirements.

Pro QC offers a range of supplier due diligence and supplier evaluation support. Our experts visit suppliers to assess their capabilities, mitigate the risk of scams, overpromises, and miscommunication, and validate their credentials, trustworthiness, and financial stability.

Pro QC’s Quality Solutions:

Supplier Risks & Challenges:

3. Supplier Qualification

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 establishes a global audit program to systematically onboard new suppliers, categorize their risk levels, and establish a reaction plan based on the supplier’s performance on quality systems, environmental management, and social and ethical compliance.

Pro QC’s Quality Solutions:

Global Supplier Audit Programs
Supplier Quality Audit for Potential Suppliers

Social & Ethical Audits

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

4. Pre-Production Validation

Before commencing volume production, it is crucial to validate that the equipment, staffing, production methods, capacity, and quality control plan are in place for each product line.

Pro QC offers on-site quality support to prevent and reduce the potential cost of poor quality (COPQ) and risk, ensuring a smooth transition from product development to mass production.

Pro QC’s Quality Solutions:

Engineering Build (EB) and Quality Build (QB) Audit

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

5. Production Planning

Production planning ensures that the supplier has sufficient raw materials, components, and staff and that other outsourced processes meet the specified schedule.

Pro QC offers assistance in timely supplier communication, onsite visits, and daily or weekly monitoring reports. This minimizes the risks of delays from ineffective procurement planning, staff shortages, or sub-supplier mismanagement.

Pro QC’s Quality Solutions:

Order Expediting
Resident Supplier Quality Resourcing

Supplier Risks & Challenges:

Production delay due to poor material procurement planning
Production delay due to inadequate production staffing
Poor sub-supplier management

6. Incoming Quality Control

Incoming inspection reflects a factory's commitment to quality control from the outset. Understanding how a factory manages its incoming material and its supply chain is a very good indication of its commitment to quality.

Pro QC quality solutions address issues such as defect acceptance, material substitutions, and component decay due to poor practices or storage conditions.

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

7. Production & Assembly

Many things can go wrong during mass production due to machine failure, lack of process control, and operator mistakes. While it is normal for defects to occur, these defects must be detected and contained.

Pro QC offers a range of support to verify control plan adherence, early defect detection, quality improvement, and issue resolution through monitoring, investigations, and CAPA validation.

Pro QC’s Quality Solutions:

First Article Inspection (FAI)
In-Process Inspection
Manufacturing Process Improvement

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

8. Outgoing QC & Shipping

The smallest aesthetic defect on the packaging or missing components can lead to customer returns, while a misplaced label may result in compliance issues. Outgoing Quality Control is the last line of defense before products are properly loaded into containers for shipment.

Pro QC offers pre-shipment inspections and end-of-line testing to ensure your products meet your quality requirements and reduce the chance of returns or re-work.
