TS ISO 9004-4

TS ISO 9004-4 is the fourth part of the Quality management and quality system elements series, focused on management guidance for continuous quality improvement within an organization. It presents quality improvement as a management-led discipline, not merely as inspection or defect correction, and links it to goals, process review, and sustained leadership commitment.

The management dimension of quality improvement

In general technical terms, quality improvement is a systematic effort to make products, services, or processes more consistent, more effective, and better aligned with customer needs. Within quality management, it is associated with reducing nonconformities, controlling process variation, using feedback, and turning improvement into an organizational habit. The focus of this part is guidance on how that approach is handled at management level.

How this part frames the key distinctions

• Improvement is broader than correcting existing defects; it aims at lasting performance gains.
• Quality control concentrates on checking outcomes, while quality improvement addresses root causes and system behavior.
• Management is central for setting objectives, providing resources, prioritizing actions, and supporting an improvement culture.
• The standard provides guidance for continuous improvement inside an organization and is not limited to a single product type or one specific test method.

Adopted by TSE on the basis of ISO 9004-4, this standard helps organizations working with quality systems interpret improvement efforts within a common framework. It is therefore a useful conceptual reference for users concerned with quality objectives, process monitoring, and stronger management responsibility for improvement.
