Total quality management (TQM)
Total quality management is a comprehensive approach to long-term success through customer satisfaction and continuous improvement across all processes. In procurement, TQM principles extend quality management to supplier selection, development, and ongoing performance.
Examples
Supplier quality systems: Procurement requires key suppliers to maintain certified quality management systems (ISO 9001), conduct regular internal audits, and demonstrate continuous improvement through documented corrective actions and quality metrics.
Incoming quality integration: Rather than relying solely on incoming inspection, TQM pushes quality responsibility to suppliers through process capability requirements, statistical process control, and source inspection—preventing defects rather than detecting them.
Cross-functional quality improvement: When field failures trace to a supplied component, procurement facilitates root cause analysis with the supplier, engineering, and quality—implementing corrective actions that prevent recurrence rather than just replacing defective parts.
Definition
TQM recognizes that quality is not just an inspection activity but a management philosophy that pervades every process and decision. Applied to procurement, it means building quality into supplier selection, specification development, and ongoing management rather than inspecting it in after receipt.
The procurement implications of TQM include: selecting suppliers based on quality capability (not just price), investing in supplier quality development, establishing statistical requirements for process control, and managing suppliers as partners in quality improvement rather than adversaries to be policed.
Prevention over detection is a core TQM principle with direct procurement application. Every dollar spent preventing quality issues at the supplier (through capability assessment, process requirements, and technical support) saves multiples in inspection, rejection, rework, and field failure costs downstream.
Continuous improvement (kaizen) requires procurement to set escalating quality expectations over time. A supplier meeting today's standards should be expected to improve, and procurement should support that improvement through feedback, benchmarking, and collaborative problem-solving.
