PURPOSE & SCOPE
Build a shared visual vocabulary
The training deck aims to help staff recognize defects that may occur in different product types, understand what to check and detect defective products. It asks users to select the material appropriate to the product being inspected.
For sourcing teams, the representative images provide a quick introduction. For supplier quality engineers (SQEs), each group opens into the full set of included examples and source references.
These are training reference images. They are not all identified as this factory’s shipment defects. Brands, characters and labels within photographs do not imply a customer relationship or endorsement. This page does not establish a training course, certification scheme or a universal acceptance standard.
01 / VISUAL DEFECT ATLAS
Visual Defect Atlas by Product Detail
Browse documented examples of molding, assembly, printing, packaging and display defects. Start with two examples in each theme, then expand the group. Comparison sets remain intact. Select an image to inspect it, or use its image-file link.
The seven themes are editorial browsing groups. Original source references remain attached to the examples. Source photographs vary in resolution; image zoom stops at their supplied detail.

BIQC Workflow Reference
The workbook’s Sheet5 shows the following sequence with six downward arrows. It starts at the OQC accepted-product area.
- OQC accepted-product areaSheet5 · E5:H7
- Tapping and screw function confirmation in the BIQC roomSheet5 · E12:H14
- BIQC functional confirmationSheet5 · E19:H21
- BIQC functional confirmation: OKSheet5 · E26:H28
- BIQC accepted-product areaSheet5 · E33:H36
- Product appearance confirmation before packagingSheet5 · E41:H44
- BIQC check for missed inspection: OK, then the next operationSheet5 · E49:H52
Read only what the flow records
“Tapping,” “screw function confirmation” and “check for missed inspection” translate the recorded actions. The sheet does not specify tapping force, number of repetitions or a detailed method for these checks.
The final box records an OK confirmation before the next operation. It is not evidence of a measured zero-miss rate. No rejection or rework branch is shown in this flow.
This is a supporting reference from the supplied workbook. It does not by itself describe the complete quality-management system or an in-process inspection procedure.
03 / ORIGINAL MATERIAL REFERENCES

Open image file: Training-board overview ↗Source version, coverage and reading limits
Training PPT: 24 actual slides. The cover states revised 28 May 2019, R:04. Slides 1–3 and 6 introduce the purpose and contents; the other 20 slides contain examples. References on this page use actual slide positions.
Contents mismatch: the contents pages refer to pages through 32 and list dedicated wood-product and sewn-product sections that are absent from the supplied deck. Those missing chapters have not been reconstructed.
One image withheld: the middle image on slide 4 is labeled “insect wings,” but the photograph and marked area do not establish that label clearly. It is omitted from the defect atlas pending source clarification.
BIQC workbook: all three sheets were reviewed. Sheet5 supplies the seven-step flow. Sheet1 supplies the room-sign photo and slogan-area layout. Sheet2 supplies one embedded training-board image, repeating the PPT’s 20 example pages; it is shown once as an overview.
The original working files remain private. Small source images and labels have not been enhanced to invent missing detail. The acronym BIQC is retained as supplied.
04 / COMPETENCE PLANNING & ASSESSMENT
Inspector Competence & Training Effectiveness
The visual atlas supports learning. The resource-management procedure supplies the wider control: identify what the role requires, provide appropriate training and evaluate its effectiveness.
- Identify the role's needsDepartment leaders identify training needs from the quality responsibilities and skills of each role.
- Plan and provide trainingHuman Resources coordinates the approved training plan; Quality and Production provide the relevant quality and operating instruction.
- Assess understanding and applicationUse the appropriate written, oral or practical assessment, and retain the training and assessment record.
- Review effectiveness in the rolePeriodic sample assessments check whether staff remain capable of the assigned work and identify where further action is needed.
Prepare for the actual assignment
Training needs include induction, instruction before taking up a role and relevant training when moving to a different workshop or job. Applicable process documents and operating skills form part of that preparation.
For an inspector, review the product-specific specification, reference sample and current inspection instruction alongside the relevant defect examples. A photograph can help recognize a condition; the approved requirement determines the decision.
A supplier review can request an appropriate completed example linking the role, training content, assessment and effectiveness follow-up. A blank form or attendance list alone cannot establish competence.
05 / HONEST INSPECTION RECORDS
Record the result that was actually observed
The quality-record procedure requires clear, complete, truthful and accurate records, with assigned responsibility for collection, filing and access. The quality-culture and ethics procedure reinforces honest reporting and fair inspection decisions.
- Record actual observations and results against the applicable requirement.
- Report defects and concerns through the assigned quality route.
- Do not fabricate results, hide nonconformity, alter a decision without authority or release rejected goods without approval.
- Protect customer, technical and quality information from unauthorized access or disclosure.
These are documented expectations. Their application is assessed through the relevant records, supervision and follow-up; this page does not claim a completed training event or an inspector certification.
06 / READING THE TRAINING MATERIAL
Inspector training questions
What can an inspector learn from these visual examples?
The supplied training material aims to help staff recognize defects that can occur in different products and understand what to inspect. The photographs show defect locations and selected comparisons. The source asks users to choose material appropriate to the product type.
Do these photographs define acceptance criteria for every product?
No. This page is a defect-recognition reference. It does not establish universal tolerances or replace the applicable product specification, reference sample or inspection standard. Read the separate Appearance Inspection page when reviewing that standard’s criteria.
How should OK, NG and CR:1PC be read?
OK and NG identify the acceptable and unacceptable views in the specific source comparison. CR:1PC is retained on the loose-button example from slide 10, where the button detaches when pulled by hand. It is not presented here as a general sampling plan or acceptance rule.
How do the visual references relate to competence controls?
The deck is marked revised 28 May 2019, R:04; that identifies its source version. The two visual source files do not establish inspector certification. Separate resource-management procedures define role-based training planning, assessment and effectiveness review. Completed training and assessment records are needed to evaluate their implementation.
How is training effectiveness assessed?
The resource procedure uses written, oral or practical assessment as appropriate, followed by periodic sampling of staff competence to evaluate whether training remains effective for the role. New assignments and relevant work instructions also inform training needs. Attendance alone does not show that an inspector can apply the required criteria.
What record-keeping behavior is expected of inspectors?
The quality-record and ethics procedures call for truthful, complete and accurate records, protection of confidential information and escalation of quality concerns. They prohibit fabricated results, concealed nonconformity, unauthorized changes to inspection results and unauthorized release of rejected product.
