What Does a Global Tier 1 Exactly Do Anyways....FYI.... I found this useful for me....MOO
..... (understanding manufacturing) What is an OEM?
OEM stands for original equipment manufacturer. The OEM is the company whose name and brand is on the final package. For example, BMW is an OEM for cars, HP is an OEM for computers, Samsung is an OEM for…well, a lot of things.
Despite being referred to as the OEM, they make little to nothing of what’s in the final product. They do, however, handle the design, branding, and overall scope of the project. At the end of the day, it’s considered their product.
But in order to actually make that product a reality, they turn to tier 1 suppliers.
Tier 1 Suppliers
Tier 1 suppliers are manufacturers that deal directly with OEM companies. These are often major companies in their own right. You may recognize names like Bosch or BASF. Though Bosch is primarily a tier 1 supplier for the automotive industry, they’re also well known for their own power tool product lines.
That means they’re also an OEM. This isn’t unheard of. Samsung is also a tier 1 supplier. Their parts can be found (ironically) in iPhones, for example.
Parts from a tier 1 supplier tend to be primary (and complex) components.
Tier 2 Suppliers
While tier 1 suppliers are creating parts and equipment, they generally don’t make the pieces that make up those parts. For that, they turn to tier 2 suppliers. Tier 2 suppliers deal directly with the tier 1 suppliers, not the OEMs.
......(parks) ....The auto industry is among the most recognized Tier-1 supply chain structure. Companies like Continental, Bosch, Denso, Panasonic Automotive, and Magna, among others, design and develop whole systems or modules for a vehicle, while sourcing individual components for the system from farther up the supply chain. The auto OEM focuses on the overall design of their vehicles, assembly of various vehicle systems, balance of their product portfolios, product marketing, developing sales strategies, and other mission-critical tasks.
...Most companies are limited in how many projects they can do at once; they can focus on mission-critical things, and everything else is a nice-to-have or just goes to the wayside. A Tier 1 structure allows companies to outsource research and development time and costs to specialists, which can extend and broaden projects/deployments.
