Quality Management in Commercial Production

Quality management is a combination of processes and tools that ensure products consistently meet customer and industry standards.
The three key pillars of quality management are:
1. Quality Control (QC)
2. Statistical Process Control (SPC)
3. Quality Assurance (QA)

Quality Control (QC): Monitoring Products for Consistency

Definition

Quality control

Quality Control (QC) is the process of inspecting products at specific stages of production to ensure they meet predefined quality standards.

Think of it as a safety net—designed to catch defects before products reach the customer.
This process is typically reactive, focusing on identifying and addressing issues during or after production.

Example

In an automobile assembly line, QC might involve checking whether car doors align perfectly or whether the paint job is free of blemishes.
If a defect is found, production can be paused or adjusted to fix the issue.

Role of QC in Waste Reduction

One of the most significant benefits of QC is its ability to reduce waste.
By identifying defects early in the production process, manufacturers can avoid wasting materials, labor, and time on defective products.
This is often referred to as QC at source, which means inspecting products as soon as they are made, rather than waiting until the end of production.

Example

Imagine a factory producing glass bottles.
If a QC check identifies a defect in the mold during the early stages, the issue can be corrected immediately.
This prevents hundreds of defective bottles from being produced, saving both material and energy.

Hint

Remember: The earlier a defect is detected, the less costly it is to fix. QC at source is a cornerstone of lean production principles.

Statistical Process Control (SPC): Using Data to Optimize Processes

Definition

Statistical process control (SPC)

Statistical Process Control (SPC) is a method that uses statistical tools to monitor, control, and improve production processes.

It involves collecting data from the production line and analyzing it to detect:
