Most supply chains are complex, but in the fashion industry, this complexity is extreme — even though it might not appear that way on the surface. The complexity of fashion supply chains comes from their tiered nature; each supplier you engage with engages suppliers of their own, resulting in a supply chain comprising multiple tiers. Tier 1 suppliers source from Tier 2 suppliers, and so on.
When calculating the final impact of a product, you need to consider every link in the chain. In McKinsey’s 2019 State of Fashion report, Leonardo Bonanni explains: “An apparel company might think that they only have 1,000 to 2,000 suppliers, but the reality is they have 20,000 to 50,000 when you count all the sub-suppliers. It’s a real challenge [for brands] to map their supply chain because there are too many third parties involved.”
The sheer size and complexity of apparel supply chains makes supply chain management alone very difficult, without adding environmental performance to the mix.
