Pre-Production Stage (Batch setting Time)
Correlation of Fabric on defects – 10% random (4-Point). Warehouse Vs Factory.
>> Central warehouse has to send its inspection report to factory on issue of fabric. One copy of report to be given to Merchandiser.
>> Factory warehouse, on receipt of fabric from central warehouse, has to randomly inspect 10% of fabric received by 4-point inspection system.
>> Factory warehouse has to prepare a report for the above inspection conducted.
>> Factory QA & HO QA has to compare the results of the inspection of Factory & warehouse. Authenticate correctness of the reports & accuracy of the same. Keep Central Warehouse QA team in loop.
>> Upon rejections & deviations from the prescribed specification, seek approval on the same from the Customer via Merchandiser.

Verification of Shade segregation for wash/Non-wash garments against given shade swatches.
>> Verify the shade segregation done by the factory for wash/Non-Wash garments against the available standard.
>> Guide factories on shade segregation so as to comply with the approved swatches.
>> Seek approval on deviation in the bulk lot against the available standard.

Co-Ordinate with merchants & obtain approvals, washing & hand feel standards.
Trims Card approvals in co-ordination with merchandiser.
Approvals on Embroidery & Print Strike Off.
Test Approvals as specified by the buyer & follow-up status.
>> QA team has to seek testing requirements for the style & follow-up on the same with merchandiser.
>> QA team has to seek approved standards w.r.t colour standards, wash effect, embroidery, printing, hand feel, trims & accessories swatch card etc from the merchandiser to follow during the bulk production.
>> QA team has to make a checklist of all the tests & approvals to be required for the style & at various stages of manufacturing processes and for various embellishments involved in the garment.
>> QA team has to follow up with merchants periodically on the status of the approvals.
>> QA team has to co-ordinate between factory & merchants on updating status of approvals.

Fusing Validation in compliance with specifications.
>> QA team has to educate production team on the use of fusing, areas fusing are required, way the fusing has to be cut, temperature & pressure to be set for fusing.

Factory Marker verification against the HO & validation
>> QA team has to verify the Marker used by the factory in terms of efficiency & quality, compare & analyze it with marker prescribed by HO team.
>> QA team has to prescribe usage of the most efficient marker among the two & ensure the usage of the same.
>> If same style is split among factories, then markers of all the factories have to be compared & most efficient marker to be prescribed for use.

Pattern Measurement Report
Clarification/Co-ordination on the measurement adjustment with the sample room
>> QA team has to verify & certify the correctness of the patterns w.r.t allowances required, constructions simplification & meeting the spec with in the tolerance.
>> QA team has to duly consider the Pre & Post sewing treatments on the fabric & garments while verifying & certifying the pattern. They have to check on the allowances required to meet the specifications after these processes.

Audit on condition of M/cs set for new styles affecting the quality of garments.
>> QA team has to audit on the condition of the M/cs that would affect the productivity & quality of the garment along with the assistance of Maintenance & IE team.
>> A checklist w.r.t the same has to be prepared & periodically followed up during the bulk production, batch setting.
>> QA team has to advise maintenance team to follow the same during its preventive maintenance schedule.

Trims Inspection whether carried out by warehouse – 10% random + checklist.
>> QA team has to create a process of trims inspection.
In-House Pre-Production Meetings.
Preparation of defect route for inline for every style
>> QA team has to arrange Pre-Production meetings for the new styles to be loaded in the factory.
>> Factory Production & Quality team to be involved in the meeting along with a PAM team member.
>> Minutes of the meeting (Action Plan) to be documented & later to be used as a checklist (Action Plan Checklist) during bulk production.
>> PAM notes to be discussed during the pre-production meeting.
>> Critical checkpoints where inline inspection would be required have to be decided.
>> Critical operations where mockups have to be posted have to be decided.
Recut Panels Analysis & reporting (1st Cut to 3rd Cut).
Verification on rejected panels
>> QA Team to analyze & monitor recut % day wise.
>> QA Team to evaluate the reason for recutting & work on action plan for immediate implementation. Upon implementation recut % to gradually reduce on comparison to previous day.
>> QA team to randomly, periodically, evaluates the panels inspected by QC & certifies the correctness of the decision taken.
>> QA teams to monitor Recut % for every style.
Audit the condition of the pattern used for marker drawing
>> Upon usage there will be wear & tear in the pattern, this has to be regularly monitored to ensure cutting quality.
>> If the patterns are worn out, it has to be replicated & cross verified against the requirements.
>> Worn out patterns are to be destroyed after confirmation on the correctness of the specifications.
