SPC for manufacturing

integrating SPC into your operations

As we navigate the complex world of manufacturing, it's crucial to understand how Statistical Process Control (SPC) fits into the larger framework of quality management.

From Total Quality Management (TQM) to Six Sigma, SPC has established itself as an integral component of these methodologies, seamlessly woven into the fabric of operations management.

  • SPC and acceptance sampling
  • SPC and reliability


In terms of TQM, SPC is the backbone of continuous improvement. SPC drives organizations to refine their processes and elevate their standards. With a good SPC system in place, manufacturers can ensure that their processes remain stable, predictable, and efficient, which is the very essence of TQM.

SPC in operations management

When it comes to operations management, SPC is a vital tool for monitoring and controlling processes in real-time, leading to increased productivity, reduced waste, and consistently high-quality products.


Both SPC and SQC share the same goal of maintaining quality, but they vary in the following ways:

  • SPC focuses on analyzing processes during production.
  • SQC is primarily concerned with inspecting finished products. 

Together, they form a comprehensive approach to quality control, with SPC playing a proactive role and SQC serving as a reactive measure.

SPC and Six Sigma methodology

In the context of Six Sigma, SPC is a key player, providing a data-driven foundation for identifying and addressing the root causes of defects. Leveraging SPC within the Six Sigma framework enables organizations to reach new heights in process capability and customer satisfaction.

SPC and quality improvement

SPC is a catalyst for positive quality improvements. It helps to systematically identify and address process variations, allowing manufacturers to continually enhance the quality of their products and services, all while reducing costs and boosting efficiency.

SPC and acceptance sampling

SPC is a valuable tool for acceptance sampling. SPC techniques enable manufacturers to make informed decisions about whether to accept or reject a batch of products based on data-driven insights.

SPC and reliability

SPC contributes significantly to the overarching goal of reliability. Consistently monitoring processes and addressing potential issues helps manufacturers to deliver products that meet or exceed customer expectations, building long-term trust and satisfaction.
