3) Mistake: Failing to map the full supply chain

Solution: Create a full bill of materials and a supplier map, including mills, dyers, and finishers. Use traceability tools to identify risk hotspots and implement corrective actions quickly.

4) Mistake: Overlooking the total cost of ownership

Solution: Consider lifecycle costs, including durability, repairability, and end-of-life options. A higher upfront price can translate into lower long-term costs due to durability and less waste.

5) Mistake: Selecting partners without a clear pilot plan

Solution: Run a defined pilot with fixed milestones, sample acceptance criteria, and exit criteria. Document the results to support a data-driven decision to scale or switch.

6) Mistake: Ignoring worker welfare and social compliance

Solution: Require regular social audits and a public policy on worker safety. Integrate supplier codes of conduct into contracts and review performance quarterly.

7) Mistake: Inadequate collaboration between design and sourcing

Solution: Involve designers early for fabric and trim decisions that align with sustainability goals. Iterative proto-sampling reduces waste and speeds up approvals.

8) Expert insider tip: Prioritize partners with circular design capability
