After the development of the tech pack, negotiations between factories and brands are a natural next step. Materials and colors often depend on market availability or budget considerations, and adjustments may need to be made to align with these constraints. Measurement clarifications are also common, as factories may have different methods for measuring and developing patterns. As a product developer, I oversee the sampling and product development process to ensure all requirements from the tech pack are followed. If certain elements need adjustments due to feasibility or availability, I update the tech pack accordingly. Additionally, I collaborate with you to review prototype samples, identify potential issues, and implement solutions to ensure the final product is ready for seamless bulk production.
