Chapter 8: Supplier Quality Management
Managing the quality of inputs from suppliers to ensure the quality of the final product or service.
I. Key concepts in supplier quality management
Consistency, reliability, and conformity to specifications
Supplier quality audits
Quality assurance and control
Processes and tools for ensuring quality and identifying defects
Statistical process control (SPC): SPC involves using statistical methods to monitor and control a process, with the goal of identifying and correcting issues before they result in defects. Key tools in SPC include control charts, which track process data over time and flag any significant changes or trends that could indicate a problem.
Failure mode and effects analysis (FMEA): FMEA is a structured approach to identifying and mitigating potential failures in a product or process. It involves breaking down a process into its component parts, analyzing the potential failure modes for each part, and then developing strategies to prevent or mitigate those failures.
Six Sigma: Six Sigma is a data-driven approach to quality management that aims to minimize defects and variation in a process. It involves defining the problem, measuring the current performance, analyzing the root cause of issues, improving the process, and then controlling the process to sustain the improvements.

Total quality management
Total cost of ownership
Evaluating the full cost of working with a supplier, including direct and indirect costs
II. Supplier selection and evaluation
Establishing evaluation criteria:
Organizations need to identify the factors that are most important to them when selecting and evaluating suppliers. These might include quality, delivery times, cost, innovation, sustainability, and other considerations.
Scorecards provide a structured way to assess supplier performance across different criteria. They typically involve assigning weights to each criterion, measuring supplier performance, and then generating a score that reflects overall performance.
Supplier performance measurement
To track supplier performance over time, organizations need to establish metrics and key performance indicators (KPIs) that reflect the factors that are most important to them. This might include metrics like defect rates, on-time delivery, lead times, and responsiveness to issues.
III. Managing supplier quality
Inspecting incoming materials and components to ensure they meet quality standards
Inspecting materials and components during production to identify defects and prevent issues
Statistical process control
Inspecting finished products to ensure they meet quality standards
Addressing defects and quality issues through root cause analysis and corrective actions
IV. Strategies for improving supplier quality
Building strong partnerships with suppliers to improve communication and collaboration
Supplier relationship management
Establishing long-term relationships with suppliers to encourage investment in quality and continuous improvement
Working with suppliers to identify opportunities for process improvement and efficiency gains
Value stream mapping
Certifying suppliers based on their quality management systems and performance
V. Challenges in supplier quality management
Communication and cultural differences
Overcoming language and cultural barriers to effective communication and collaboration
Quality control across multiple suppliers
Ensuring consistent quality across multiple suppliers and supply chains
Supplier collaboration and integration
Supplier capacity and flexibility
Managing supplier capacity and flexibility to meet changing demand and market conditions
Cost and time constraints
Balancing quality and cost considerations within tight timelines and budget constraints
