Pre-Production Quality Control System in Garments Industry

Pre-production quality assessment and control is the critical point for the garments industry. PP sample defines the correctness of measurement, shade, and construction of garments. Pre-Production Quality Control System in Garments Industry is set to check factory is able to produce full bulk orders without any issue. It is the preparation process of mass production.

Receiving Spec sheet, Materials, and QC File

Before starting pre-production sampling few important documents need to the quality department. Among them are spec sheets, PO sheets and QC files (trim cards) are the most urgent items. These documents help to know garments specification, size breakdown, measurements, and exact BOM sheet of an order.

Pre-production sampling –Size Set

Pre-production sampling (Size Set) aims to identify potential quality problems during bulk production as well as the availability of skill, machinery, work aids, and production capacity. The Pre-production quality control covers sampling activities done by production upon receipt of Approved Sealed Sample comments from the customer plus other necessities for production like actual fabrics, trims, and other order details. It is the responsibility of the Pre-production Control team to implement the procedure or system. It shall be composed of the following. The involved persons are Sample Room Head, Production Head, sewing in-charge, Technician, QA Manager, Cutting Room in-charge, Technical in-charge, IE, Planning & Finishing in-charge

Size set Sampling Procedure

  1. The sample room must ensure that Pattern adjustments/Grading is made based on within 3 days upon receipt of the buyer’s final approval comments.
  2. The planning department shall plan the schedule of the size set based on the master production Schedule.
  3. The technical team shall make the size set in alignment with the sewing team where it is planned for bulk production. The use of possible work aids like sewing Folders needs to be tried during making a size set.
  4. The Planning Department must ensure that the following information is available to the production line during the process of making the size set. Approved sample with complete specification sheet with Final approval comments. Actual fabric and trims should use in PP/ Size set sample
  5. Respective line QA shall be tasked to make an initial evaluation using the Size Set Report
  6. The Pre-production team shall evaluate the size set in terms of workmanship, and fit/presentation and formulate possible sets of solutions in accordance with the following agenda during the PP meeting.
  7. Fabric Characteristics at cutting, Possible spreading and Cutting method, anticipated sewing difficulty, and methods, Potential quality problems in all aspects of production, Availability of work aids, machines, and skills, and Number of pieces to be made shall depend from customer to customer.

Initial/pilot production

The first trial lay of production considered the Initial/pilot lot. It is actually the first cutting load to the sewing line and the time to apply the anticipated method is foreseen during PPS/Size Set stage.
