Aerospace supply chain is a huge system of different levels (or “tiers”) of suppliers to the companies that ultimately assemble aircraft. So you could be working in the supply chain department of an aircraft manufacturer (“prime” company), bringing together wings, with engines and other large components. Or perhaps you’ll be in a tier 1 company, making a wing and bringing in parts from tier 2 companies who supply your materials and bolts. No matter the tier of company, making your supply chain work effectively saves time and money, helping to increase profits for your company.
