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.
