A tech pack is a blueprint or spec sheet to get your designs made. Think of it as an instruction manual with the exact steps and materials required to manufacture your product. With a complete tech pack, the factory should be able to make your entire product perfectly without having to ask any questions. The goal is to minimise the number of photos/samples, decrease costs and speed up production time. It also serves as a master document to track product development including comments, revisions and changes made.
Your tech pack acts as a living breathing document to track the entire product development process, so anytime you make any change (no matter how small), you’ll want to make a note of that in your fashion tech pack. The best practice is to note what you changed something from and what you changed it to and a reason, if applicable. This helps keep your factory accountable and responsible for implementing all changes.
