What can be done with retained quality-control data?
Quality control data can only serve as a basis for supplier assessment when it is aggregated by defect type and batch.
Common questions found in AIWhat can be done with retained quality-control data?
Acceptance is the true delivery.
The value of quality-control data lies not in the current batch, but in the next one. It tells you which direction the problem is moving.
misread:It's enough to keep the inspection records; they can be reviewed if something goes wrong.Actual circumstances:Data that is neither aggregated nor categorized can be retrieved for individual batches, but no trends can be discerned.
There is also a common misconception:Just keep the data.In fact:The data must be aggregated by defect type in order to serve as a basis for negotiations.
Basis for Determination
Three applications: defect classification statistics (which type of defect is most common), batch trends (whether a given defect is increasing), and supplier comparisons (for the same type of defect, which supplier is more reliable). All three provide a way to work backward and identify where the process needs improvement.
- classification of defects
- Batch trend
- Supplier Comparison
Acceptance Sequence
Minimum implementation requirements: record the type and quantity of defects for each batch and compile the data monthly. No complex system is required—a single table is sufficient; the key is consistency.
- Record by defect type, not just as pass or fail.
- Group by supplier and batch to generate trends.
- Publish a supplier quality dashboard once per quarter.
- Use predefined options for defect types; do not enter them freely.
Applicable boundaries: For projects with a single supplier, the data is primarily used for improvement and not for comparison.
On-site settings and practices we have observed
A company keeps inspection records for every incoming shipment, resulting in several thick volumes. When it comes to evaluating a supplier, however, they can't provide conclusions such as the rework rate or the main types of defects. The data is all there, but without structure, it's like starting from scratch every time an assessment is made.
When INNOPACKING assists clients with quality-control data, it first establishes a defect classification system and then aggregates the data by supplier. Once the data has a clear structure, it provides a solid basis for negotiations: instead of saying, "Your quality is inconsistent," you can state, "Delamination accounts for 62% of your defects." A kanban board need not be complex; a single table with three columns is sufficient: supplier, defect type, and proportion. Once the data can be ranked, negotiations become possible. After six months of data accumulation, the sampling inspection ratio can be adjusted accordingly, allowing resources to be focused on suppliers with the most frequent issues.

What can quality control data be used for?
Classify defects by type and batch and use the results as the basis for supplier assessment. Data lacking structure is merely documentation.
How should you keep records to make them useful?
Defect types are assigned fixed options, summarized by supplier and batch, with a visual management board issued quarterly.
How long should the data be stored?
At least two years. For exports and food products, it is recommended to store them for one year beyond their shelf life.
