Product Development is the conversion of the details (sketch) and reference of the style given by a Buyer in the form of Tech-Pack, into a Sample garment called the First Proto Sample, which undergoes several approval stages from the Buyer before the final sample called the Sealer Sample is sealed or finalized.

Techpacks are sometimes provided by the Buyer or even sometimes created by the Production House according to the buyer requirements and specifications. To get it right the first time in raw material planning, garment construction, style detailing, etc., it is very important to carefully study the tech-pack prior to start order processing. If the tech pack is reviewed with a detailed checklist, sample correction can be reduced in approval stages. Garment costing and production preparation can be done more accurately.
