SOP – Sampling Approval

SOP: Sampling Approval

Objective

   v  To study in detail the samples for development like construction, fit, Material characteristic to styling, and production work methods.

   v  To ensure that specification details received from the buyer are processed according to their requirements.

Scope

   v  This procedure shall cover sampling from sample development stages up to the time it is finally approved by the latter for bulk production.

Authority

   v  This procedure is issued and controlled by the Sample Section Manager.

Area of responsibility

   v  It is the responsibility of the Head of Sample Section to ensure that Standard operating Procedures (SOP) are enforced.

Procedure

Patterns

   v  If Patterns received from the buyer will be verified against customer’s specification.

   v  In case of any discrepancy, Sample section shall inform Merchandising Department by accomplishing details buyer pattern against spec discrepancy or any.

   v  If no patterns received from buyer, earlier approved patterns of similar style of same buyer will be used as base for Fit/Pattern Balance and patterns adjusted as per required spec.

   v  Patterns should be added process allowance for sewing/ cutting loss and the same will be verified during test sample.

Wash Shrinkage

   v  For Wash styles, washing shrinkage should be tested as per wash standard required.

   v  Always add the tested/ actual Washing shrinkage into the patterns.

   v  Always need to mention, Pattern measurements (Spec + Process allowance + Washing Shrinkage), Target Before wash (Spec + Washing shrinkage).

   v  Target Before wash measurement – Always pattern maker to provide Target Before wash (TBW) measurements for critical POMs – Waist, Seat, Thigh, Knee, Bottom opening & Inseam.

   v  Before wash measurement – Before wash measurements should be checked against Target Before wash measurement not against Final Spec.

Construction

   v  Technicians / QA/ IE teams identify Potential Production difficulties related to Construction/ sewing methods.

   v  Samples should be made with constructions which are feasible for bulk run.

   v  Always try to use Folders in order to get consistent quality with higher productivity.

   v  Factory Option - If the construction requested by the buyer is not feasible for bulk, then always provide a factory option during development/ Fit sampling stage.

   v  Option A -Follow construction detail exactly as per customer requirements

   v  Option B – Factory option along with parent sample to achieve consistent quality & productivity without affecting/ altering style and aesthetic look of the garment.

   v  All clarifications related to construction, Research and development should be cleared during development and Fit sampling stage.

   v  Construction cannot be changed once the PP sample is approved.

Rejections Analysis

   v  In case of rejections, detailed analysis done by concern pattern maker along with sample section manager and any clarification required on comments will be communicated to buyer prior to making patterns.

   v  Factory Option: Other than making the samples as per buyer comments, in case factory feels to advise suggestions for better fitting, factory provides another sample made as per factory suggestion in addition to parent sample following buyer comments AS IS.

New Buyer

   v  Whenever there is a new buyer, a meeting is called with concern merchandising team and below details requested to have better understanding of new buyer prior to process samples.

   v  Patterns - Whether buyer provides Block patterns or AS IS patterns to make sampling or do we need to develop patterns from our end.

   v  Body form – Details of body form or live model measurements.

   v  Sample stages - What are the sample stages involved?

   v  How to measure Manual for way of measuring and guidelines for sample making if any from buyer.

Size Set Patterns

   v  PP approval comments been incorporated in base pattern within 3 days of PP sample comments receipt. Any discrepancy in following fit comments is highlighted to buyer prior to proceeding graded patterns for size set.

  v  Pattern maker make the graded patterns as per the buyer graded spec, any discrepancy in grading rule will be communicated to buyer.

   v  Graded patterns released to CAD team with signature of Pattern Maker for making size set. Note – Wash shrinkage followed is PP sample shrinkage. Grading checked by a person responsible to check the grading.

   v  CAD team to adjust the Graded pattern as per washing shrinkage of Size Set Fabric and release the size set patterns with Target Before wash measurements for Critical Measurements.

Size Set Review

   v  Size set before wash measurements been measured against TBW measurements and the same been recorded.

   v  Size set measured after wash.

   v  QA team to do the Size set analysis - Pattern measurements, before wash measurements, after wash measurements and shrinkage, suggest pattern corrections to concern pattern maker.

   v  Pattern maker to review the QA team suggestion and verify the size set report against size set samples prior to making corrections for Pilot run patterns.
