Write a report on the supply chain of a product of your choice made by a company in the fashion/clothing sector. Analyse, evaluate and make solid recommendations to enhancing the supply chain of the organisation.

Your report should focus on the following key tasks:

1. Map the supply chain of your product (including at least 4 tiers) and identify the role of different firms/companies involved in this supply chain
2. Evaluate opportunities in the product lifecycle to improve sustainability
3. Critically analyse the potential challenges of effectively managing this supply chain and provide recommendations to address these challenges.
